Recent Longevity News for the seven days ending 6/26/13.  You should consult your doctor if you are taking any medications.

Breastfeeding Boosts Ability to Climb Social Ladder - Science Daily, 6/25/13 - "children who had been breastfed were consistently more likely to have climbed the social ladder than those who had not been breastfed ... Breastfeeding increased the odds of upwards mobility by 24% and reduced the odds of downward mobility by around 20% for both groups ... breastfeeding enhances brain development, which boosts intellect, which in turn increases upwards social mobility. Breastfed children also showed fewer signs of stress"

CVD Reduced With Metformin, Higher With Rosiglitazone - Medscape, 6/24/13 - "In 29 different studies, metformin was associated with a 10% reduction in the risk of cardiovascular events, with the drug associated with a 10% reduction in the risk of heart failure in seven studies and a 12% reduction in the risk of MI in nine studies. In contrast, rosiglitazone was associated with a 21% increased risk of cardiovascular events in 25 studies, a 27% increased risk of heart failure in 13 studies, and a 17% increased risk of MI in 21 studies"

Iron Deficiency Linked to Psychiatric Disorders in Kids - Medscape, 6/24/13 - "Children and adolescents with iron deficiency anemia (IDA) are at increased risk for psychiatric disorders, including depressive disorder, bipolar disorder, anxiety disorder, and autism ... should check the iron level in those children and adolescents with psychiatric disorders ... Iron plays a key role in brain development, including myelination of white matter and the development and functioning of the different neurotransmitter systems, including the dopamine, norepinephrine, and serotonin systems ... There is well-documented evidence in the literature that IDA has a significant influence on cognitive development, intelligence, and developmental delay ... Odds Ratio ... Bipolar disorder ... 5.80"

U-shaped curve revealed for association between fish consumption and atrial fibrillation - Science Daily, 6/24/13 - "The study found a U-shaped association between consumption of marine n-3 polyunsaturated fatty acids (n-3 PUFA) and the risk of developing AF, with people who have both low and high intakes found to suffer more from AF than those with median intakes. The lowest risk of AF was found in those who consumed around 0.63 g marine n-3 PUFA per day, which corresponds to around two servings of fatty (oily) fish per week ... Earlier studies have reported that regular consumption of fish can exert beneficial effects in preventing the development of AF. Notably, in the Cardiovascular Health study², which included 4,815 participants, a 28% lower risk of AF was observed among people who consumed fish one to four times per week compared with those who ate fish less than once per month. However, such observed associations have not been confirmed in all cohort studies" - Note:  I wouldn't go by one study plus that's just one disease.

Findings emphasize importance of vitamin D in pregnancy - Science Daily, 6/22/13 - "While current studies suggest that around a fifth (19 per cent) of a newborn baby's supply or deficiency of vitamin D comes directly from its mother, experts from Kingston's School of Life Sciences have discovered that the figure is, in fact, almost three times as high at 56 per cent ... focused on 120 samples taken from 60 Greek mothers and their babies ... Although the Mediterranean nation enjoys more hours of sunshine than the United Kingdom, the research revealed that many of the mothers had low levels of vitamin D ... the type of vitamin D commonly measured in blood tests was not as reliable an indicator of vitamin D activity as other strands. They went on to discover that two epimer forms, previously thought to be unimportant, influenced levels in babies" - See vitamin D at Amazon.com.

Thirdhand smoke causes DNA damage - Science Daily, 6/20/13 - "has found for the first time that thirdhand smoke -- the noxious residue that clings to virtually all surfaces long after the secondhand smoke from a cigarette has cleared out -- causes significant genetic damage in human cells ... Tobacco-specific nitrosamines, some of the chemical compounds in thirdhand smoke, are among the most potent carcinogens there are. They stay on surfaces, and when those surfaces are clothing or carpets, the danger to children is especially serious ... thirdhand smoke can cause both DNA strand breaks and oxidative DNA damage, which can lead to gene mutation ... it can still be detected in dust and surfaces of apartments more than two months after smokers moved out. Common cleaning methods such as vacuuming, wiping and ventilation have not proven effective in lowering nicotine contamination"

Dietary fructose causes liver damage in animal model - Science Daily, 6/19/13 - "The big question for the researchers was what caused the liver damage. Was it because the animals got fat from eating too much, or was it something else? ... To answer that question, this study was designed to prevent weight gain. Ten middle-aged, normal weight monkeys who had never eaten fructose were divided into two groups based on comparable body shapes and waist circumference. Over six weeks, one group was fed a calorie-controlled diet consisting of 24 percent fructose, while the control group was fed a calorie-controlled diet with only a negligible amount of fructose, approximately 0.5 percent ... Both diets had the same amount of fat, carbohydrate and protein, but the sources were different ... high-fructose group's diet was made from flour, butter, pork fat, eggs and fructose (the main ingredient in corn syrup), similar to what many people eat, while the control group's diet was made from healthy complex carbohydrates and soy protein ... What surprised us the most was how quickly the liver was affected and how extensive the damage was, especially without weight gain as a factor"

HPV Vaccines Working Despite Limited Use - ABC News, 6/19/13 - "The HPV infection rate among girls between the ages of 14 and 19 dropped by 56 percent with the arrival of the vaccines Cervarix and Gardasil ... The CDC urges boys to get vaccinated against HPV ... While a single dose of the HPV vaccines was found to cut the risk of HPV infection by 82 percent, clinical trials suggest the protection rises to 96 percent with all three doses"

L-thyroxine Dampens Renal Function Decline in CKD With SCH - Medscape, 6/19/13 - "In patients with stage 2 to 4 chronic kidney disease (CKD) and subclinical hypothyroidism (SCH), thyroid hormone replacement therapy (THRT) with L-thyroxine appeared to dampen the rate of decline in renal function ... studied 113 patients with stable CKD who were treated at their center with L-thyroxine for subclinical hypothyroidism and who had data for at least 24 months before and after THRT ... mean age of 63, and 32% were men ... The patients received L-thyroxine (Synthyroid, Bukwang Pharmacy) at a dose needed to normalize serum TSH levels. The usual starting dose was 25 µg/day and was increased as needed until the patient attained a normal serum TSH level ... On average, before the patients received THRT, eGFR declined by 4.31 mL/min/1.73 m2 each year, but after they received THRT, this slowed significantly, to a decline of 1.08 mL/min/1.73 m2 each year" - Note:  I throw studies like this in because it would make sense that it might also reduce the decline in kidney function with normal aging.

Tea and Coffee Lower Blood Pressure - Medscape, 6/18/13 - "After adjustments that included these and other potential confounding variables, both coffee and tea consumption was associated with a significant reduction in systolic and diastolic blood pressure, as well as other variables" - See the table.  For coffee, no coffee was 127.9 for none, 1 - 4 cups was 126.7 and > 4 cups was 125.5 on the systolic.

Skipping Breakfast May Raise Diabetes Risk - WebMD, 6/18/13 - "The new study included only nine women. Their average age was 29, and all were overweight or obese ... measured their levels of insulin and blood sugar on two different days after the women ate lunch. On one day, they had eaten breakfast; on the other day, they had skipped it ... the women's insulin and glucose levels after lunch were much higher on the day they skipped breakfast than on the day they ate it ... There was a 28 percent increase in the insulin response and a 12 percent increase in the glucose response after skipping breakfast"

Getting enough sleep could help prevent type 2 diabetes - Science Daily, 5/18/13 - "studied 19 non-diabetic men, with an average age of 28.6 years, who for six months or longer (average, 5.1 years) self-reported inadequate sleep during the workweek. On average, the men received only 6.2 hours of sleep each work night. But they regularly caught up on their sleep on the weekends, sleeping an extra 37.4 percent, or 2.3 hours, per night ... When the men slept 10 hours a night on each of three nights of catch-up sleep, their insulin sensitivity was much better than when they had persistent sleep restriction, the scientists found. Their insulin resistance test score also improved (decreased) with sleep extension"

Herbal Extract Boosts Fruit Fly Lifespan by Nearly 25 Percent - Science Daily, 6/18/13 - "Rhodiola works in a manner completely unrelated to dietary restriction and affects different molecular pathways ... Rhodiola can act even in individuals who are already long-lived and healthy. This is quite unlike resveratrol, which appears to only act in overfed or unhealthy individuals ... Not only did Rhodiola improve lifespan an average of 24 percent in both sexes and multiple strains of flies, but it also delayed the loss of physical performance in flies as they aged and even extended the lives of old flies ... Rhodiola has already shown possible health benefits in humans, such as decreasing fatigue, anxiety and depression; boosting mood, memory and stamina; and preventing altitude sickness" - See Rhodiola rosea at Amazon.com.

Cutting Back on Red Meat May Lower Risk for Type 2 Diabetes - Medscape, 6/18/13 - "Reducing red-meat consumption by more than half a serving per day over a 4-year follow-up did not confer a reduced risk for incident type 2 diabetes in the subsequent 4 years, but it was associated with a 14% reduced risk during a 12- to 16-year follow-up"

Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

Effects of synbiotic food consumption on metabolic status of diabetic patients: A double-blind randomized cross-over controlled clinical trial - Clin Nutr. 2013 Jun 7 - "This randomized double-blinded cross-over controlled clinical trial was performed among 62 diabetic patients aged 35-70 y. After a 2-wk run-in period, subjects were randomly assigned to consume either a synbiotic (n = 62) or control food (n = 62) for 6 weeks ... The synbiotic food consisted of a probiotic viable and heat-resistant Lactobacillus sporogenes (1 × 107 CFU), 0.04 g inulin (HPX) as prebiotic with 0.38 g isomalt, 0.36 g sorbitol and 0.05 g stevia as sweetener per 1 g. Control food (the same substance without probiotic bacteria and prebiotic inulin) was packed in identical 9-gram packages. Patients were asked to consume the synbiotic and control foods three times a day ... In conclusion, consumption of a synbiotic food for 6 weeks among diabetic patients had significant effects on serum insulin, hs-CRP, uric acid and plasma total GSH levels" - Note:  I not sure whether they are talking about probiotic supplements added to the food or something like yogurt.  See probiotic products at Amazon.com and my yogurt recipe at the top of my Yogurt Page.

Low vitamin D status is an independent predictor of increased frailty and all-cause mortality in older men: the Health In Men Study - J Clin Endocrinol Metab. 2013 Jun 20 - "4203 older men aged 70-88 years in Perth, Western Australia ... After a mean period of 5.3 years, the adjusted odds ratio of being frail at follow-up for men with low vitamin D and having zero deficit at baseline (FRAIL scale = 0) was 1.56 (95% CI 1.07 to 2.27). Low vitamin D also predicted all-cause mortality over a period of up to 9.2 years (hazards ratio 1.20, 95% CI 1.02 to 1.42), independent of baseline frailty and other covariates" - See vitamin D at Amazon.com.

Effects of long-chain PUFA supplementation in infant formula on cognitive function in later childhood - Am J Clin Nutr. 2013 Jun 19 - "Infants were randomly assigned to receive formula containing either docosahexaenoic acid and arachidonic acid or no LC-PUFAs for a period of 4 mo. A reference breastfed group was also included. In a follow-up conducted at age 6 y, children received assessments of intelligence quotient (IQ), attention control (Day-Night Test), and speed of processing on the Matching Familiar Figures Test (MFFT) ... IQ scores of children who were fed a formula containing either LC-PUFAs or no LC-PUFAs did not differ at age 6 y. However, children who received LC-PUFAs were faster at processing information compared with children who received unsupplemented formula. Variation in the dietary supply of LC-PUFAs in the first months of life may have long-term consequences for the development of some cognitive functions in later childhood" - See Jarrow Max DHA at Amazon.com.

Coffee and Tea Consumption Are Inversely Associated with Mortality in a Multiethnic Urban Population - J Nutr. 2013 Jun 19 - "mean follow-up of 11 y ... Coffee consumption was inversely associated with all-cause mortality [for each additional cup/d, HR = 0.93 (95% CI: 0.88, 0.99); P = 0.02]. Caffeinated coffee was inversely associated with all-cause mortality, driven by a strong protection among those who drank ≥4 cups/d. An inverse dose-response relationship between tea and all-cause mortality was suggested [for each additional cup/d, HR = 0.91 (95% CI: 0.84, 0.99); P = 0.01]. Coffee consumption ≥4/d was protective against nonvascular death [vs. <1/mo, HR = 0.57 (95% CI: 0.33, 0.97)] and tea consumption ≥2/d was protective against nonvascular death [HR = 0.63 (95% CI: 0.41, 0.95)] and cancer [HR = 0.33 (95% CI: 0.14, 0.80)]. There was a strong inverse association between coffee and vascular-related mortality among Hispanics only"

Effect of green tea on reward learning in healthy individuals: a randomized, double-blind, placebo-controlled pilot study - Nutr J. 2013 Jun 18;12(1):84 - "Seventy-four healthy subjects participated in a double-blind, randomized placebo-controlled study with oral administration of green tea or placebo for 5weeks. We used the monetary incentive delay task to evaluate the reward learning by measurement of the response to reward trial or no-reward trial. We compared the reaction time of reward responsiveness between green tea and placebo treatment. Furthermore, we selected Montgomery-Asberg depression rating scale (MADRS) and 17-item Hamilton Rating Scale for Depression (HRSD-17) to estimate the depressive symptoms in these two groups ... The results showed chronic treatment of green tea increased reward learning compared with placebo by decreasing the reaction time in monetary incentive delay task. Moreover, participants treated with green tea showed reduced scores measured in MADRS and HRSD-17 compared with participants treated with placebo" - See green tea extract at Amazon.com.

News & Research:

  • Predictors of increased body weight and waist circumference for middle-aged adults - Public Health Nutr. 2013 May 1:1-11 - "Prospective cohort study, the Melbourne Collaborative Cohort Study (MCCS), with data at baseline (1990-1994) and wave 2 (2003-2007) ... Our findings indicate that promoting vigorous physical activity, encouraging a diet high in carbohydrate and fibre but low in fat and protein, and limiting alcohol intake could be promising approaches for preventing obesity in middle-aged adults"
  • Protein-rich breakfasts prevent unhealthy snacking in the evening, study finds - Science Daily, 3/26/13 - "20 overweight or obese adolescent females ages 18-20 either skipped breakfast, consumed a high-protein breakfast consisting of eggs and lean beef, or ate a normal-protein breakfast of ready-to-eat cereal. Every breakfast consisted of 350 calories and was matched for dietary fat, fiber, sugar and energy density. The high-protein breakfast contained 35 grams of protein ... The consumption of the high-protein breakfast led to increased fullness or "satiety" along with reductions in brain activity that is responsible for controlling food cravings. The high-protein breakfast also reduced evening snacking on high-fat and high-sugar foods compared to when breakfast was skipped or when a normal protein, ready-to-eat cereal breakfast was consumed ...Study participants ate egg and beef-based foods such as burritos or egg-based waffles with applesauce and a beef sausage patty as part of a high-protein breakfast; Leidy also suggests eating plain Greek yogurt, cottage cheese or ground pork loin as alternatives to reach the 35 grams of protein"
  • Chromium supplementation in overweight and obesity: a systematic review and meta-analysis of randomized clinical trials - Obes Rev. 2013 Mar 18 - "Electronic searches were conducted in Medline, Embase, Amed and The Cochrane Library ... A meta-analysis of 11 studies showed a statistically significant difference in weight loss favouring chromium over placebo (mean difference (MD): -0.50 kg; 95% confidence interval (CI): -0.97, -0.03). There was a high statistical heterogeneity. Adverse events included watery stools, vertigo, headaches and urticaria. The evidence from available RCTs shows that chromium supplementation generates statistically significant reductions in body weight" - See chromium supplements at Amazon.com.
  • Olive Oil Makes You Feel Full - Science Daily, 3/14/13 - "While it is true that they contain fewer calories, people tend to overcompensate by eating more if they do not feel full. Now a study has shown how "natural" oils and fats regulate the sensation of feeling full after eating, with olive oil leading the way ...Over a period of three months, the study participants ate 500 grams of low-fat yoghurt enriched with one of the four fats or oils every day -- as a supplement to their normal diet ... The olive oil group showed a higher concentration of the satiety hormone serotonin in their blood. Subjectively speaking, these participants also reported that they found the olive oil yoghurt very filling ... During the study period, no member of this group recorded an increase in their body fat percentage or their weight ... How long the feeling of satiety lasts after eating depends on a number of factors, but blood sugar level is particularly significant. The faster it falls, that is to say, the faster the somatic cells absorb glucose from the blood, the sooner the person will start to feel hungry again"
  • Lose fat faster before breakfast - Science Daily, 1/25/13 - "those who had exercised in the morning did not consume additional calories or experience increased appetite during the day to compensate for their earlier activity ... They also found that those who had exercised in a fasted state burned almost 20% more fat compared to those who had consumed breakfast before their workout. This means that performing exercise on an empty stomach provides the most desirable outcome for fat loss"
  • Carbs at night can help you lose weight - Today Health, 1/20/13 - "In the study, researchers split 78 Israeli police officers into two groups and placed them on nearly identical 6-month-long low-calorie diets (1,300 to 1,500 calories a day) eating equal amount of carbs, protein, and fat throughout the day. The only difference: Half of the officers ate the majority of their carbs at night while the other half ate them throughout the day. At the start and end of the study, researchers analyzed blood hormone levels while the cops recorded their hunger levels ... Nighttime carb eaters lost 27 percent more body fat than people on the standard diet. Surprisingly, they also felt 13.7 percent fuller at the end of the study than the beginning, while regular dieters were hungrier. What's more, the level of inflammatory hormones -- which can lead to heart disease and cancer -- in the nighttime group's blood decreased by 27.8 percent compared to only 5.8 percent in the standard dieters" - Note:  So maybe carbs at night and eggs in the morning might be a strategy:
    • Eggs at Breakfast May Delay Hunger - WebMD, 5/11/12 - "researchers tracked 20 overweight or obese people, giving them either a breakfast containing eggs or cold cereal for one week. Although the breakfasts offered different protein foods, the meals themselves were equally matched in terms of calories, carbohydrates, protein, and fat ... people who had eggs in the morning felt fuller before lunch, and they also ate less food from the buffet compared to those who had cereal. Egg eaters also had lower levels of ghrelin and higher amounts of PYY3-36 during the three hours between breakfast and lunch. This suggests they felt less hungry and more satisfied between meals ... Long-term weight loss trials to compare the manipulation of protein quality without increasing protein quantity should be explored"
  • Higher-protein diet for weight management in young overweight women: a 12 month randomised controlled trial - Diabetes Obes Metab. 2012 Dec 26 - "This randomised controlled trial compared the efficacy of two iso-energetically restricted (5600kJ) diets (HP: 32% protein, 41% carbohydrate, 25% fat or HC: 20, 58, 21% respectively) in 71 (HP:n=36; HC:n=35) young healthy women (18-25y; BMI≥27.5kg/m(2) ) for weight (kg; percent weight loss), body composition, metabolic and iron changes assessed at baseline, six and 12 months ... No significant between-diet differences were observed at 12 months. Biochemistry remained within normal ranges with HP showing superior preservation of ferritin at six months (HP:53(40-66); HC:46(30-61)µg/L; p=0.029). Both diets supported clinically meaningful weight loss with HP tending to be more effective in the medium-term"
  • Aerobic exercise trumps resistance training for weight and fat loss - Science Daily, 12/15/12 - "Participants were randomly assigned to one of three exercise training groups: resistance training (three days per week of weight lifting, three sets per day, 8-12 repetitions per set), aerobic training (approximately 12 miles per week), or aerobic plus resistance training (three days a week, three set per day, 8-12 repetitions per set for resistance training, plus approximately 12 miles per week of aerobic exercise) ... The groups assigned to aerobic training and aerobic plus resistance training lost more weight than those who did just resistance training. The resistance training group actually gained weight due to an increase in lean body mass ... The combination exercise group, while requiring double the time commitment, provided a mixed result. The regimen helped participants lose weight and fat mass, but did not significantly reduce body mass nor fat mass over aerobic training alone. This group did notice the largest decrease in waist circumference, which may be attributed to the amount of time participants spent exercising ... Balancing time commitments against health benefits, our study suggests that aerobic exercise is the best option for reducing fat mass and body mass"
  • Low fat diet is key to a slimmer figure, study suggests - Science Daily, 12/6/12 - "Exchanging fatty foods for lower fat alternatives will help people shift around three-and-a-half pounds -- without any other form of dieting. People taking part in trials also saw their waist-lines become slimmer, and levels of bad cholesterol decrease ... The results show that eating less fat reduces body weight by 1.6kg, BMI by 0.56kg/m² and waist circumference by 0.5cm. All these effects were in trials in which weight loss was not the intended outcome, suggesting that they occur in people with normal diets. The weight loss happened quickly and was maintained over at least seven years"
  • Could high insulin make you fat? Mouse study says yes - Science Daily, 12/4/12 - "When we eat too much, obesity may develop as a result of chronically high insulin levels, not the other way around ... The new study helps to solve this chicken-or-the-egg dilemma by showing that animals with persistently lower insulin stay trim even as they indulge themselves on a high-fat, all-you-can-eat buffet ... the researchers produced mice that varied only in their fasting blood insulin levels. When presented with high-fat food, those with one copy and lower fasting insulin were completely protected from obesity even without any loss of appetite. They also enjoyed lower levels of inflammation and less fat in their livers, too ... the researchers produced mice that varied only in their fasting blood insulin levels. When presented with high-fat food, those with one copy and lower fasting insulin were completely protected from obesity even without any loss of appetite. They also enjoyed lower levels of inflammation and less fat in their livers, too"
  • Changes in bread consumption and 4-year changes in adiposity in Spanish subjects at high cardiovascular risk - Br J Nutr. 2012 Dec 3:1-10 - "We analysed 2213 participants at high risk for CVD from the PREvención con DIeta MEDiterránea (PREDIMED) trial to assess the association between changes in the consumption of bread and weight and waist circumference gain over time. Dietary habits were assessed with validated FFQ at baseline and repeatedly every year during 4 years of follow-up ... The present results showed that over 4 years, participants in the highest quartile of change in white bread intake gained 0.76 kg [1.7 pounds] more than those in the lowest quartile (P for trend = 0.003) and 1.28 cm [0.5 inches] more than those in the lowest quartile (P for trend < 0.001) ... The present results suggest that reducing white bread, but not whole-grain bread consumption, within a Mediterranean-style food pattern setting is associated with lower gains in weight and abdominal fat"
  • New research: Limiting carbs to dinner-time increases satiety, reduces risk for diabetes and cardiovascular disease - Science Daily, 11/11/12 - "randomly assigned 78 police officers to either the experimental diet (carbohydrates at dinner) or a control weight loss diet (carbohydrates throughout the day). 63 subjects finished the six-month program ... researchers examined the experimental diet's effect on the secretion of three hormones: leptin, considered to be the satiety hormone, whose level in the blood is usually low during the day and high during the night; ghrelin, considered the hunger hormone, whose level in the blood is usually high during the day and low during the night; and adiponectin, considered the link between obesity, insulin resistance and the metabolic syndrome, whose curve is low and flat in obese people ... the innovative dietary manipulation led to changes in daylight hormonal profiles in favor of the dieters: the satiety hormone leptin's secretion curve became convex during daylight hours with a nadir in the late day; the hunger hormone ghrelin's secretion curve became concave, peaking only in the evening hours; and the curve of adiponectin, considered the link between obesity, insulin resistance and the metabolic syndrome, was elevated. At the same time this dietary pattern led to lower hunger scores, and better anthropometric (weight, abdominal circumference and body fat), biochemical (blood sugar, blood lipids) and inflammatory outcomes compared to the control group"
  • Effect of green tea (camellia sinensis) consumption on the components of metabolic syndrome in elderly - J Nutr Health Aging. 2012;16(9):738-42 - "The consumption of green tea was effective in inducing weight loss, reducing BMI and waist circumference in the elderly with MS" - See green tea extract at Amazon.com.
  • Soups increase satiety through delayed gastric emptying yet increased glycaemic response - Eur J Clin Nutr. 2012 Oct 24 - "A total of 12 volunteers were tested on three occasions after a solid meal, chunky soup or smooth soup test meal for gastric emptying (GE) ... glycaemic response (GR) ... The smooth soup had the greatest GR (87.0+/-49.5 mmol/l/min), followed by the chunky soup (65.4+/-48.0 mmol/l/min), with the solid meal having the lowest GR (61.6+/-36.8 mmol/l/min). Volunteers were fuller after the smooth soup compared with solid meal (P=0.034). The smooth soup induced greater fullness compared with the solid meal because of a combination of delayed GE leading to feelings of gastric distension and rapid accessibility of nutrients causing a greater glycaemic response" - Note:  I was flipping through the channels a couple weeks ago and on one of the major networks was a dietician recommending soup as a major contribution to satiety.
  • Regulation of brown adipose tissue development and white fat reduction by L-arginine - Curr Opin Clin Nutr Metab Care. 2012 Nov;15(6):529-38 - "Brown adipose tissue (BAT), which is present in humans, plays an important role in oxidation of fatty acids and glucose ... L-arginine increases mammalian BAT growth and development via mechanisms involving gene expression, nitric oxide signaling, and protein synthesis. This enhances the oxidation of energy substrates and, thus, reduces white fat accretion in the body. L-arginine holds great promise in preventing and treating obesity in humans" - See L-arginine products at Amazon.com.
  • Effect of DHEA-S on Metabolic Syndrome in Obese Women: Abstract and Introduction - Medscape, 10/12/12 - "Dehydroepiandrosterone-sulphate replacement produced weight loss in the obese women studied. Moreover, waist circumference, glucose and systolic and diastolic blood pressure, among other metabolic syndrome parameters, improved in the postmenopausal group, who showed a significant reduction in the total metabolic syndrome score (P < 0.05). In contrast, in premenopausal women, the effect of DHEA-S was limited to obesity parameters, and no effect was observed on metabolic syndrome components. No significant changes were evident in the placebo group" - See DHEA at Amazon.com.
  • Apple peel compound boosts brown fat, reduces obesity in mice - Science Daily, 6/20/12 - "The findings suggest that the substance known as ursolic acid reduces obesity and its associated health problems by increasing the amount of muscle and brown fat, two tissues recognized for their calorie-burning properties ... In this study, we tested ursolic acid in mice on a high-fat diet -- a mouse model of obesity and metabolic syndrome. Once again, ursolic acid increased skeletal muscle. Interestingly, it also reduced obesity, pre-diabetes and fatty liver disease ... Since muscle is very good at burning calories, the increased muscle in ursolic acid-treated mice may be sufficient to explain how ursolic acid reduces obesity. However, we were surprised to find that ursolic acid also increased brown fat, a fantastic calorie burner. This increase in brown fat may also help protect against obesity" - See ursolic acid at Amazon.com.
  • Eggs at Breakfast May Delay Hunger - WebMD, 5/11/12 - "researchers tracked 20 overweight or obese people, giving them either a breakfast containing eggs or cold cereal for one week. Although the breakfasts offered different protein foods, the meals themselves were equally matched in terms of calories, carbohydrates, protein, and fat ... people who had eggs in the morning felt fuller before lunch, and they also ate less food from the buffet compared to those who had cereal. Egg eaters also had lower levels of ghrelin and higher amounts of PYY3-36 during the three hours between breakfast and lunch. This suggests they felt less hungry and more satisfied between meals ... Long-term weight loss trials to compare the manipulation of protein quality without increasing protein quantity should be explored" - Note:  I fully agree.  I just seems very easy to keep my weight in check when I have eggs for breakfast.
  • Metformin-based treatment for obesity-related hypertension: a randomized, double-blind, placebo-controlled trial - J Hypertens. 2012 Apr 19 - "metformin (500 mg once per day) or placebo ... At 24 weeks, metformin compared with placebo did not have significant effects on blood pressure, blood glucose, high-density or low-density lipoprotein cholesterol, but it did reduce total serum cholesterol (0.27mmol/l, P = 0.038). Metformin also significantly reduced weight (-0.7 kg, P = 0.006), BMI (-0.2 kg/m, P = 0.024), waist circumference (-0.9 cm, P = 0.008), and both subcutaneous (-6.1 cm, P = 0.043) and visceral adiposity (-5.4 cm, P = 0.028) as measured by computed tomography, and lowered serum high-sensitivity C-reactive protein levels (-0.6 mg/dl, P < 0.001). There was no significant difference in adverse events" - See metformin at IAS.
  • Potential method to control obesity: Red wine, fruit compound could help block fat cell formation - Science Daily, 4/4/12 - "A compound found in red wine, grapes and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity ... the compound piceatannol blocks an immature fat cell's ability to develop and grow ... piceatannol binds to insulin receptors of immature fat cells in the first stage of adipogenesis, blocking insulin's ability to control cell cycles and activate genes that carry out further stages of fat cell formation. Piceatannol essentially blocks the pathways necessary for immature fat cells to mature and grow" - See grape seed extract at Amazon.com.
  • Coffee Bean Extract Linked to Weight Loss - ABC News, 3/27/12 - "Researchers gave up to 1,050 milligrams of green coffee bean extract to 16 overweight adults in their 20s and monitored their diet, exercise regimen, weight, heart rate and blood pressure for 22 weeks. Without changing their diet or exercise, study subjects lost roughly 10.5 percent — an average of 17 pounds – in overall body weight. No harmful side effects were noted ... How green coffee bean extract contributes to weight loss is unclear. But Vinson theorizes a chemical in the unroasted bean called chlorogenic acid could be responsible" - See green coffee bean extract at Amazon.com.

  • Evaluation of the usefulness of a low-calorie diet with or without bread in the treatment of overweight/obesity - Clin Nutr. 2011 Dec 30 - "The aim of this study was to compare two nutrition strategies (with or without bread) designed to promote weight loss in overweight/obese women ... 104 women completed the study (48.4 +/- 9 years, 29.8 +/- 3.5 kg/m(2)). Anthropometric and biochemical markers improved after the intervention without significant differences between groups. BREAD group significantly increased total cereal consumption (3.2 +/- 1.3 to 3.7 +/- 0.5 servings/day, P < 0.05) and the percentage of energy from carbohydrates (41.2 +/- 6.4 vs. 45.9 +/- 5.0% P < 0.001) and reduced fat (39.0 +/- 6.6 vs. 32.7 +/- 5.1% P < 0.001). In contrast, NO BREAD group increased the discrepancy with recommended consumption. NO BREAD group had the most dropouts (21.3% vs. 6.6%, P < 0.05) ...

  • Diferential Effect of Oral Dehydroepiandrosterone-Sulphate on Metabolic Syndrome Features in Pre- and Postmenopausal Obese Women - Clin Endocrinol (Oxf). 2011 Dec 2 - "To analyze the effect in obese pre- and postmenopausal women of a daily dose of 100 mg Dehydroepiandrosterone-sulphate (DHEA-S) provided over a period of 3 months as replacement therapy against Metabolic-Syndrome ... DHEA-S replacement produced weight loss in the obese women studied. Moreover, waist-circumference, glucose and systolic and diastolic blood pressure, among other Metabolic-Syndrome parameters, improved in the postmenopausal group, who showed a significant reduction in the total Metabolic-Syndrome Score (P<0.05). In contrast, in premenopausal women, the effect of DHEA-S was limited to obesity parameters and no effect was observed on Metabolic-Syndrome components. No significant changes were evident in the placebo group. Conclusions:  An oral dose of DHEA-S is useful for weight loss. In obese postmenopausal women the hormone significantly improves plasma biochemical levels and anthropometric characteristics, leading to a better metabolic profile, which highlights the usefulness of this therapy against Metabolic-Syndrome in this group of women" - See DHEA at Amazon.com.
  • Korean Red Ginseng (Panax ginseng) Improves Insulin Sensitivity in High Fat Fed Sprague-Dawley Rats - Phytother Res. 2011 Oct 28 - "Many studies have documented that ginseng has antidiabetic and antiobesity effects, but the mechanism of the effects has not been elucidated. The aim of this study was to determine the effect of Korean red ginseng (KRG, Panax ginseng) and investigate the mechanism of antidiabetic and antiobesity effects in obese insulin resistant animal models. Sprague-Dawley (SD) rats were divided into three groups: a control group (group I) fed a normal diet, another group (group II) fed only high fat diet (HFD) and a third group (group III) fed HFD with KRG (200 mg/kg, oral) for 18 weeks ... A significant weight reduction, especially fat mass reduction, was observed in the KRG treated group. Increased insulin sensitivity was found in the KRG treated group. We observed increased insulin signalling, increased phosphorylation of IR, IRS-1, Akt, and membranous GLUT4 in muscle by Western blotting assay. In conclusion, KRG may have antidiabetic and antiobesity effects due to partly increased insulin sensitivity by increased adipokine and partly enhanced insulin signalling" - See ginseng at Amazon.com.
  • Watching Your Protein May Be Key to Weight Control - WebMD, 10/12/11 - "men and women fed a 10% protein diet ate 12% more calories over four days than they did on a 15% protein diet ... When protein in the diet goes too low, ''We keep eating in an attempt to attain our target level of protein," ... As the protein declined to 10%, the men and women tended to eat more carbohydrates and fat-containing food, boosting the risk for weight gain. But Gosby found that increasing the protein from 15% to 25% didn't seem to make any difference in total calories eaten ... Aiming at 15%-25% of total energy intake as protein seems about right for a moderately active person" - [Science Daily]
  • Green tea helps mice keep off extra pounds - Science Daily, 10/4/11 - "in the current online version of Obesity, fed two groups of mice a high-fat diet. Mice that were fed Epigallocatechin-3-gallate -- EGCG -- a compound found in most green teas, along with a high-fat diet, gained weight 45 percent more slowly than the control group of mice eating the same diet without EGCG ... In addition to lower weight gain, the mice fed the green tea supplement showed a nearly 30 percent increase in fecal lipids, suggesting that the EGCG was limiting fat absorption ... A person would need to drink ten cups of green tea each day to match the amount of EGCG used in the study" - See green tea extract at Amazon.com.

  • Foods rich in protein, dairy products help dieters preserve muscle and lose belly fat - Science Daily, 8/29/11 - "a higher-protein, lower-carbohydrate energy-restricted diet has a major positive impact on body composition, trimming belly fat and increasing lean muscle, particularly when the proteins come from dairy products ... compared three groups of overweight and obese, but otherwise healthy, premenopausal women. Each consumed either low, medium or high amounts of dairy foods coupled with higher or lower amounts of protein and carbohydrates ... there were identical total weight losses among the groups, but the higher-protein, high-dairy group experienced greater whole-body fat and abdomen fat losses, greater lean mass gains and greater increases in strength ... One hundred per cent of the weight lost in the higher-protein, high-dairy group was fat. And the participants gained muscle mass, which is a major change in body composition ... the lower-protein, low-dairy group lost about a pound and half of muscle whereas the lower-protein, medium dairy group lost almost no muscle. In marked contrast, the higher-protein, high-dairy group actually gained a pound and half of muscle, representing a three-pound difference between the low- and high-dairy groups ... On top of the muscle mass differences, the higher-protein, high-dairy group lost twice as much belly fat than the lower-protein, low-dairy group ... These women also got fitter and stronger" - See my yogurt recipe on my yogurt page.
  • Eating protein throughout the day preserves muscle and physical function in dieting postmenopausal women, study suggests - Science Daily, 8/10/11 - "higher protein intake during weight loss can offset negative effects on muscle mass by maintaining more muscle relative to the amount of weight lost.

  • Is lost lean mass from intentional weight loss recovered during weight regain in postmenopausal women? - Am J Clin Nutr. 2011 Jul 27 - "All body mass and composition variables were lower immediately after weight loss than at baseline (all P < 0.05). More fat than lean mass was lost with weight loss, which resulted in body-composition changes favoring a lower percentage of body fat and a higher lean-to-fat mass ratio (P < 0.001). Considerable interindividual variability in weight regain was noted (CV = 1.07). In women who regained ≥2 kg body weight, a decreasing trend in the lean-to-fat mass ratio was observed, which indicated greater fat mass accretion than lean mass accretion (P < 0.001). Specifically, for every 1 kg fat lost during the weight-loss intervention, 0.26 kg lean tissue was lost; for every 1 kg fat regained over the following year, only 0.12 kg lean tissue was regained ... Although not all postmenopausal women who intentionally lose weight will regain it within 1 y, the data suggest that fat mass is regained to a greater degree than is lean mass in those who do experience some weight regain"
  • Increased Consumption of Dairy Foods and Protein during Diet- and Exercise-Induced Weight Loss Promotes Fat Mass Loss and Lean Mass Gain in Overweight and Obese Premenopausal Women - J Nutr. 2011 Jul 20 - "Weight loss can have substantial health benefits for overweight or obese persons; however, the ratio of fat:lean tissue loss may be more important. We aimed to determine how daily exercise (resistance and/or aerobic) and a hypoenergetic diet varying in protein and calcium content from dairy foods would affect the composition of weight lost in otherwise healthy, premenopausal, overweight, and obese women. Ninety participants were randomized to 3 groups (n = 30/group): high protein, high dairy (HPHD), adequate protein, medium dairy (APMD), and adequate protein, low dairy (APLD) differing in the quantity of total dietary protein and dairy food-source protein consumed: 30 and 15%, 15 and 7.5%, or 15 and <2% of energy, respectively. Body composition was measured by DXA at 0, 8, and 16 wk and MRI (n = 39) to assess visceral adipose tissue (VAT) volume at 0 and 16 wk. All groups lost body weight (P < 0.05) and fat (P < 0.01); however, fat loss during wk 8-16 was greater in the HPHD group than in the APMD and APLD groups (P < 0.05). The HPHD group gained lean tissue with a greater increase during 8-16 wk than the APMD group, which maintained lean mass and the APLD group, which lost lean mass (P < 0.05). The HPHD group also lost more VAT as assessed by MRI (P < 0.05) and trunk fat as assessed by DXA (P < 0.005) than the APLD group. The reduction in VAT in all groups was correlated with intakes of calcium (r = 0.40; P < 0.05) and protein (r = 0.32; P < 0.05). Therefore, diet- and exercise-induced weight loss with higher protein and increased dairy product intakes promotes more favorable body composition changes in women characterized by greater total and visceral fat loss and lean mass gain" - Note:  See the yogurt recipe on my yogurt page.
  • Whey Protein May Be Helpful for Weight Loss - WebMD, 7/15/11 - "Researchers at the U.S. Department of Agriculture's Human Nutrition Research Center randomly assigned 90 overweight and obese middle-aged adults to one of three groups. The first group was asked to add protein drinks made with whey to their normal diets, the second group drank protein drinks made with soy protein, and the third group drank carbohydrate drinks ... the drinks, which were drunk twice daily, at breakfast and dinner, had the same number of calories: 200. They also all had had 52 grams per packet, for a daily total of 104 grams of added protein or carbs ... After six months, people drinking the carbohydrate shakes had gained a little bit of weight, about 2 pounds, which appeared to be mainly added fat ... People drinking the soy shakes had stayed about the same weight as where they started ... But people drinking the whey protein had lost a little bit of weight and body fat, about 2 pounds. Additionally, while the other groups saw little change in the size of their waists, the whey protein group lost about an inch around the middle ... a couple of things may help to explain the weight and fat loss seen with whey protein ... People in the whey protein group had significantly lower blood levels of the hormone ghrelin than people eating the soy protein or carbohydrate ... And though researchers really can't explain why this happened or what it means, they found that people drinking the whey protein had cut back on their carbohydrate intake by the end of the study, even though they weren't eating fewer total calories and didn't know what kind of supplement they were getting ... researchers advise picking a whey product that is also low in calories and fat" - See whey protein at Amazon.com.
  • Waistlines in people, glucose levels in mice hint at sweeteners' effects: Related studies point to the illusion of the artificial - Science Daily, 6/27/11 - "In the constant battle to lose inches or at least stay the same, we reach for the diet soda. Two studies presented June 25 and 27 at the American Diabetes Association's Scientific Sessions in San Diego suggest this might be self-defeating behavior ... diet soft drink consumption is associated with increased waist circumference in humans, and a second study that found aspartame raised fasting glucose (blood sugar) in diabetes-prone mice ... The average follow-up time was 9.5 years ... Diet soft drink users, as a group, experienced 70 percent greater increases in waist circumference compared with non-users. Frequent users, who said they consumed two or more diet sodas a day, experienced waist circumference increases that were 500 percent greater than those of non-users ... In the related project ... One group of the mice ate chow to which both aspartame and corn oil were added; the other group ate chow with the corn oil added but not the aspartame. After three months on this high-fat diet, the mice in the aspartame group showed elevated fasting glucose levels but equal or diminished insulin levels, consistent with early declines in pancreatic beta-cell function"
  • Fat substitutes linked to weight gain: Rats on high-fat diet gained more weight after eating low-calorie potato chips made with fat substitutes - Science Daily, 6/20/11 - "Half of the rats in each group also were fed Pringles potato chips that are high in fat and calories. The remaining rats in each group were fed high-calorie Pringles chips on some days and low-calorie Pringles Light chips on other days. The Pringles Light chips are made with olestra, a synthetic fat substitute that has zero calories and passes through the body undigested ... For rats on the high-fat diet, the group that ate both types of potato chips consumed more food, gained more weight and developed more fatty tissue than the rats that ate only the high-calorie chips. The fat rats also didn't lose the extra weight even after the potato chips were removed from their diet. "Based on this data, a diet that is low in fat and calories might be a better strategy for weight loss than using fat substitutes," ... Food with a sweet or fatty taste usually indicates a large number of calories, and the taste triggers various responses by the body, including salivation, hormonal secretions and metabolic reactions. Fat substitutes can interfere with that relationship when the body expects to receive a large burst of calories but is fooled by a fat substitute ... Swithers and Davidson have reported similar findings in previous rat studies that showed saccharin and other artificial sweeteners also can promote weight gain and increased body fat"
  • Cut down on 'carbs' to reduce body fat, study authors say - Science Daily, 6/5/11 - "Subjects received either a standard lower-fat diet or a diet with a modest reduction in carbohydrates, or "carbs," but slightly higher in fat than the standard diet. The moderately carb-restricted diet contained foods that had a relatively low glycemic index, a measure of the extent to which the food raises blood glucose levels. This diet consisted of 43 percent calories from carbohydrates and 39 percent calories from fat, whereas the standard diet contained 55 percent of calories from carbohydrates and 27 percent from fat. Protein made up the other 18 percent of each diet ... After the weight maintenance phase, subjects who consumed the moderately carb-restricted diet had 11 percent less deep abdominal fat than those who ate the standard diet. However, when the researchers analyzed results by race, they found it was exclusive to whites. Whites have more deep abdominal fat than Blacks even when matched for body weight or percent body fat, and may benefit from loss of this metabolically harmful depot"
  • Healthy gut flora could prevent obesity, rat study suggests - Science Daily, 5/25/11 - "Poor gut flora is believed to trigger obesity. In the same way, healthy gut flora could reduce the risk. This has shown to be the case in tests on rats. Daily intake of a lactic acid bacteria, which has been given the name Lactobacillus plantarum HEAL19, appears to be able to prevent obesity and reduce the body's low-level inflammation ... Rats who were given this specific lactic acid bacterium from their time in the uterus up to adult age put on significantly less weight than other rats. Both groups ate the same amount of high-energy food ... A third group of rats were given the inflammation-causing Escherichia coli bacteria in their drinking water, in addition to the same high-energy food as the other rats. The E. coli supplement led to changes in gut flora and increased body fat ... A healthy gut flora at an early stage appears to play a part in children's wellbeing later in life"
  • Eat a protein-rich breakfast to reduce food cravings, prevent overeating later, researcher finds - Science Daily, 5/19/11 - "eating a healthy breakfast, especially one high in protein, increases satiety and reduces hunger throughout the day.

  • Citrus extracts show energy burning potential, without side effects: Study - Nutra USA, 5/17/11 - "consumption of 100 mg hesperidin, 50 mg p-synephrine (from bitter orange), and 600 mg naringin increased the resting metabolic rate by about 18 percent ... If one assumes that the product was taken twice a day for one year, the theoretical increase in calorie consumption would amount to over 31 pounds ... None of the treatment groups exhibited changes in heart rate or blood pressure relative to the control group, nor there were no differences in self-reported ratings of 10 symptoms between the treatment groups and the control group ... the thermogenic effect of p-synephrine may be increased by naringin and hesperidin via an enhancement in the production of the expression of adiponectin, a hormone released from fat cells, which plays an important role in the regulation of insulin sensitivity and energy" - [Abstract]
  • Breakfast frequency inversely associated with BMI and body fatness in Hong Kong Chinese children aged 9-18 years - "The prevalence of obesity among breakfast skippers, semi-skippers and non-skippers was, respectively, 9.8, 10.6 and 3.8 % (P < 0.001) for primary school students and 3.9, 3.1 and 2.4 % (P < 0.001) for secondary school students. The 12 % of Hong Kong children aged 9-18 years who skipped breakfast had higher BMI, BMI z-scores and percentage of body fat (PBF) than their counterparts. The dose effects of breakfast frequency (unstandardised regression coefficient, P < 0.001) on BMI and PBF were, respectively, - 0.125 kg/m2 and - 0.219 % for boys and - 0.165 kg/m2 and - 0.353 % for girls, adjusting for physical activity per additional breakfast meal per week. Further study is recommended to elucidate whether regular breakfast consumption may have a role in the prevention of childhood obesity" - Note:  I don't know what the problem is with the "." in the actual abstract instead of the "." but I fixed it so it wouldn't be so confusing.
  • Green tea shows body weight and fat benefits: Rat study - Nutra USA, 3/30/11 - "Rats consuming green tea along with a high fat diet gained less body weight and accumulated less fat than animals not supplemented with tea, says a new study ...

  • Green tea aqueous extract reduces visceral fat and decreases protein availability in rats fed with a high-fat diet - Nutr Res. 2011 Feb;31(2):157-64 - "Green tea is associated with beneficial health effects mainly because of its body fat-reducing and hypocholesterolemic activities, but an effective dose without pronounced influence on protein availability is unknown. The objective of this study was to examine the hypothesis that green tea aqueous extract (GTAE) depending on dose improves cardiovascular risk indicators such as body weight, visceral fat content, and atherogenic index of plasma and does not have unfavorable effect on protein availability in rats fed with a high-fat diet. The rats fed with a high-fat diet enriched with 1.1 and 2.0% GTAE for 8 weeks had significantly (P < .05) lower atherogenic index (in both groups, about 14.3%). Only administration of 2.0% GTAE significantly (P < .05) decreased body weight gain (5.6%) and prevented visceral fat accumulation (17.8%) in rats. However, considerably (P < .05), reduction in the digestion of protein (but not fat) was observed in both GTAE groups (1.1% GTAE: 82.6% +/- 1.8%; 2.0% GTAE: 84.3% +/- 0.8%) when compared to the control (93.3% +/- 1.5%). It was concluded that GTAE may have preventive effects on the accumulation of visceral fat but only in higher doses. Although both doses improved cardiovascular risk indicators, they, in addition, significantly inhibited protein digestion" - See green tea extract at Amazon.com.
  • Resveratrol may be useful tool for reducing body fat - Science Daily, 3/4/11 - "This thesis shows, on the one hand, the results obtained after treatment with CLA in hamsters subjected to energy restriction and, on the other, the effect of resveratrol on accumulated fat and lipolytic activity in cell cultures of adipocytes of murinae and humans. The results obtained show that CLA does not foment weight or body fat loss, induced by an energy restriction diet. Neither does it induce greater lipolysis, nor improvement in serum parameters, in glucose homeostasis or insulin function to any greater extent than with the slimming diet itself. On the contrary, resveratrol reduces the accumulation of triglycerides, in part by activation of lipolysis, in both the adipocytes of mice and of humans ... For all these reasons, it can be concluded that, while CLA may not be a molecule useful in treating obesity, when resveratrol is included in hypocaloric diet, it could well be a useful tool for reducing body fat" - See resveratrol products at Amazon.com and conjugated linoleic acid at Amazon.com.
  • A protein-rich beverage consumed as a breakfast meal leads to weaker appetitive and dietary responses v. a protein-rich solid breakfast meal in adolescents - Br J Nutr. 2011 Feb 15:1-5 - "A total of fifteen adolescents (eight girls and seven boys; age 14 (sem 1) years, BMI percentile 79 (sem 4) %) randomly completed two testing days that included protein-rich (PR) breakfast meals (38 % of energy as protein, 48 (sem 2) g/meal) provided as a solid (S) or beverage (B). Breakfast was 24 % of estimated daily energy needs (2146 (sem 96) kJ/meal). Perceived appetite and satiety responses were collected over 5 h followed by an ad libitum lunch buffet. The PR-S meal led to greater reductions in 4 h postprandial appetite ( - 6221 (sem 1171) mm × 240 min) v. the PR-B meal ( - 3570 (sem 957) mm × 240 min; P < 0.05). When examining the data according to hourly responses, the PR-S meal led to greater reductions in appetite during postprandial hours 2, 3 and 4 v. the PR-B meal (all comparisons, P < 0.05). No differences in postprandial hourly or total (4 h) fullness were observed following the PR-S v. PR-B meals. The PR-S meal led to approximately 480 kJ less energy consumed at the ad libitum lunch buffet (1418 (sem 222) kJ) v. the PR-B meal (1900 (sem 326) kJ; P < 0.05). These data indicate that, although the food form of the PR breakfast meals had little, if any, effect on satiety, the appetitive responses were diminished and the subsequent food intake was greater when protein was consumed as a beverage v. a solid meal"
  • Effects of Metformin on Body Weight and Body Composition in Obese Insulin-Resistant Children: A Randomized Clinical Trial - Diabetes. 2011 Jan 12 - "1,000 mg metformin (n = 53) or placebo (n = 47) twice daily for 6 months ...Children prescribed metformin had significantly greater decreases in BMI (difference -1.09 kg/m(2), CI -1.87 to -0.31, P = 0.006), body weight (difference -3.38 kg, CI -5.2 to -1.57, P < 0.001), BMI Z score (difference between metformin and placebo groups -0.07, CI -0.12 to -0.01, P = 0.02), and fat mass (difference -1.40 kg, CI -2.74 to -0.06, P = 0.04). Fasting plasma glucose (P = 0.007) and homeostasis model assessment (HOMA) insulin resistance index (P = 0.006) also improved more in metformin-treated children than in placebo-treated children. Gastrointestinal symptoms were significantly more prevalent in metformin-treated children, which limited maximal tolerated dosage in 17%. During the 6-month open-label phase, children treated previously with placebo decreased their BMI Z score; those treated continuously with metformin did not significantly change BMI Z score further. CONCLUSIONS Metformin had modest but favorable effects on body weight, body composition, and glucose homeostasis in obese insulin-resistant children participating in a low-intensity weight-reduction program" - Note: 3.38 kg equals 7.4 pounds.  See metformin at IAS.

  • Eating mostly whole grains, few refined grains linked to lower body fat - Science Daily, 10/20/10 - "People who consume several servings of whole grains per day while limiting daily intake of refined grains appear to have less of a type of fat tissue thought to play a key role in triggering cardiovascular disease and type 2 diabetes ... Visceral Adipose Tissue ... VAT volume was approximately 10 % lower in adults who reported eating three or more daily servings of whole grains and who limited their intake of refined grains to less than one serving per day ... Visceral fat surrounds the intra-abdominal organs while subcutaneous fat is found just beneath the skin ... visceral fat is more closely tied to the development of metabolic syndrome ... participants who consumed, on average, three daily servings of whole grains but continued to eat many refined grains did not demonstrate lower VAT volume"
  • Too much light at night at night may lead to obesity, study finds - Science Daily, 10/11/10 - "mice exposed to a relatively dim light at night over eight weeks had a body mass gain that was about 50 percent more than other mice that lived in a standard light-dark cycle ... Something about light at night was making the mice in our study want to eat at the wrong times to properly metabolize their food ... So how does light at night lead to changes in metabolism? The researchers believe the light could disrupt levels of the hormone melatonin, which is involved in metabolism. In addition, it may disrupt the expression of clock genes, which help control when animals feed and when they are active"

    • See Yogourmet Electric Yogurt Maker - I've had a lot of yogurt makers over the years but this is the best one I've found.  I mix two cups of Nestle Nido Instant Dry Whole Milk (available at Amazon) with two cups of dry skim milk in a blender.  Lately I've been making it with Activa. I believe it's only sold flavored but I've been using the strawberry flavored Activa.  I put the milk powders in a blender then fill it with water and blend.  Then add one container of the Activa and blend fast one more time (not to kill the culture).  Then pour it into the jar and fill the jar to the top with additional water and leave it in the yoghurt maker for 13 hours.  I mix the finished product with Smucker's Strawberry Orchard's Finest.  If your worried about the BPA's from the plastic container, see Widemouth Clear Half Gallon Glass Jar (64oz) w/ White Metal Lid  at specialtybottles.com.

  • Another Cause of Obesity: The Bacteria in Your Gut? - Time Magazine, 11/12/09 - "When one group of mice was fed a typical Western diet, high in fat and sugars, they tended to gain weight and grow more Firmicutes gut bacteria and fewer Bacteroidetes. In mice given a low-fat, plant-based chow, the distribution of the two groups of bugs flipped and the animals remained lean. It's not clear whether the balance of gut bugs causes weight gain or is a result of it, but the findings suggest that a "gut profile" could potentially serve as a diagnostic tool for identifying who might have a propensity for obesity. If, for instance, your gut environment contains a preponderance of Firmicutes, then your body may be predisposed to digest calories in a way that leads to greater fat storage. In fact, in Gordon's earlier work with identical twins of different weights, he found that the obese twin tended to have more Firmicutes colonies than the leaner sibling ...factors like gut microbes, which scientists traditionally would not think of exerting influence on genes, may have a surprisingly powerful effect, changing how a body's genes would normally control the way it digest food and breaks it down into energy"

The arginine treatment reduced the relative weights of white fat pads by 30% and enhanced those of soleus muscle by 13%, extensor digitorum longus muscle by 11%, and brown fat by 34% compared with control rats ... arginine treatment resulted in lower serum concentrations of leptin, glucose, triglycerides, urea, glutamine, and branched-chain amino acids, higher serum concentrations of nitric-oxide metabolites, and improvement in glucose tolerance. Thus, dietary arginine supplementation shifts nutrient partitioning to promote muscle over fat gain and may provide a useful treatment for improving the metabolic profile and reducing body white fat in diet-induced obese rats" - See Jarrow Formulas, Arginine 1000, 1000 mg, 100 Easy-Solv Tablets at iHerb.
  • Treatment of white coat hypertension with metformin - Int Heart J. 2008 Nov;49(6):671-9 - "White coat hypertension (WCH) is most likely a disorder associated with metabolic syndrome ... Twenty-five cases (14.7%) stopped metformin therapy due to excessive anorexia. At the end of a 6-month period, there were highly significant differences between the two groups with respect to the prevalences of resolved WCH, hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, overweight and obesity, and decreased fasting plasma glucose below 110 mg/dL ... Thus, the management of WCH should not focus solely on the regulation of blood pressure with antihypertensive medications, but rather on the prevention of future excess weight and various associated disorders, and metformin alone is an effective therapeutic option, most likely due to its powerful inhibitory effect on appetite"
  • Low-carb Diets Can Affect Dieters' Cognition Skills - Science Daily, 12/11/08 - "A new study from the psychology department at Tufts University shows that when dieters eliminate carbohydrates from their meals, they performed more poorly on memory-based tasks than when they reduce calories, but maintain carbohydrates. When carbohydrates were reintroduced, cognition skills returned to normal"
  • Lack Of Vitamin D Causes Weight Gain And Stunts Growth In Girls - Science Daily, 12/11/08 - "The high prevalence of vitamin D insufficiency in young people living in a sun-rich area was surprising," says study lead author, Richard Kremer, co-director of the Musculoskeletal Axis of the MUHC. "We found young women with vitamin D insufficiency were significantly heavier, with a higher body mass index and increased abdominal fat, than young women with normal levels" - See vitamin D at Amazon.com.
  • Adiponectin Is A Metabolic Link Between Obesity And Bone Mineral Density - Science Daily, 11/25/08 - "adiponectin, a protein secreted from adipocytes, is a metabolic link that can explain, in part, the known positive relationship between obesity and both bone mineral density and reduced susceptibility to fractures ... In summary, elevated circulating adiponectin was associated with lower bone mass and weaker bones in growing mice compared to control animals" - See my adiponectin page for ways to increase it. - Ben
  • Vitamin D Insufficiency Linked to Increased Body Fat - Medscape, 11/10/08 - "The study sample consisted of 90 postpubertal women aged 16 to 22 years and living in California ... Insufficiency of 25(OH)D, defined as a serum level of 29 ng/mL or less, was present in approximately 59% of participants, and the remaining 41% had sufficient 25(OH)D levels, defined as a serum level of 30 ng/mL or more. Serum 25(OH)D levels were strongly negatively related to CT measures of visceral and subcutaneous fat and to DXA values of body fat" - See vitamin D at Amazon.com.
  • Drug 'tricks body to lose weight' - BBC News, 11/5/08 - "The drug SRT1720 - a chemical cousin of red wine extract resveratrol - targets the protein SIRT1, which is thought to combat ageing ... The French team from the University Louis Pasteur became interested in the SIRT1 protein after earlier studies showing resveratrol countered some effects of a high-calorie diet via SIRT1" - See resveratrol products at Amazon.com.
  • Chronic Green Tea Consumption Decreases Body Mass, Induces Aromatase Expression, and Changes Proliferation and Apoptosis in Adult Male Rat Adipose Tissue - J Nutr. 2008 Nov;138(11):2156-2163 - "Green tea (GT) ... These results suggest new mechanisms for GT on body weight and highlight its potential benefit to prevent or treat obesity and the metabolic syndrome" - See green tea extract at Amazon.com.
  • Fructose -- Found In High-fructose Corn Syrup, Sugar -- Sets Table For Weight Gain Without Warning - Science Daily, 10/16/08 - "Eating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet"
  • MSG Use Is Linked to Obesity - New York Times, 8/25/08 - "After controlling for body mass index, smoking, physical activity and almost two dozen measures of daily nutrient intake, they found that the one-third of people who used the most MSG were almost three times as likely to be overweight — that is, to have a body mass index over 25 — as those who used none"
  • Fructose May Make You Fatter - WebMD, 7/31/08 - "Fructose gets made into fat more quickly, and when that process is turned on there seems to be a signal that goes to the liver that says store all the other fats you are seeing"
  • Metformin May Enhance Weight Loss in Female Adolescents - Medscape, 7/8/08 - "a significant decrease in body mass index was seen in females receiving metformin but not in those taking placebo. Sixty percent of participants who were metformin-adherent and who decreased food portion sizes had a decrease in body mass index of more than 5%" - See metformin at OffshoreRx1.com.
  • 'Big Breakfast' Diet Helps Shed Pounds - WebMD, 6/17/08 - "Eating a 600-calorie breakfast rich in carbohydrates and protein helps dieters lose more weight long term than eating a modest breakfast and following a lower-carb eating plan ... In all, members of the big-breakfast group lost more than 21% of their body weight; low-carb group members lost 4.5%"
