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 ...

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"

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"

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

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"

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

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"

Hubbell Building Automation LightHAWK LHIRS1I Digital Infrared Occupancy
Sensor with Manual Override, Ivory
- Nearly all motion sensors will not work with CFL's or LED because they
require a small current to pass through them which is enough to cause a
flicker in CFL's and LED's. This has "No
minimum load requirement". The ones that work with CFL's and LED's are
hard to find and then you have to do a lot or research to see what it does
plus they are expensive ($69 while I'm writing this). The LHIRS is a motion
on/off, not like most occupancy sensors which is confusing. With most
occupancy sensors you have to manually turn it on when you enter the room
then it goes off automatically when you leave the room. Some clarify and
call it a vacancy swith. With this switch, when you walk into the room it
switches the LED's or CFL's on automatically and when you leave the room it
switches them off automatically after a preset time interval. Reminds me of
that scene in Avatar where they wall down the huge tree limb and the lights
light their path. It also has a manual override. I've had three for years
and I even removed the cover to get the right model number to be sure. eBay
has it also at this writing:
LHIRS switch for $57 with the shipping.

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"

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

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

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

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

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"

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

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

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

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.

"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 <

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

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

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

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

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"

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"

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

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"

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"

Daily, 5/7/09 - "One year after giving birth, women were
less likely to have the most dangerous kind of obesity if they had been given
probiotics from the first trimester of pregnancy, found new research that
suggests manipulating the balance of bacteria in the gut may help fight obesity
... Central obesity, where overall obesity is combined with a particularly fat
belly, is considered especially unhealthy ... We found it in 25% of the women
who had received the probiotics along with dietary counselling, compared with
43% in the women who received diet advice alone" - See

Curcumin inhibits adipogenesis in 3T3-L1 adipocytes and angiogenesis and obesity
in C57/BL mice - J Nutr. 2009 May;139(5):919-25 -
"Supplementing the high-fat diet of mice with curcumin did not affect food
intake but reduced body weight gain, adiposity, and microvessel density in
adipose tissue, which coincided with reduced expression of vascular endothelial
growth factor (VEGF) and its receptor VEGFR-2. Curcumin increased
5'AMP-activated protein kinase phosphorylation, reduced glycerol-3-phosphate
acyl transferase-1, and increased carnitine palmitoyltransferase-1 expression,
which led to increased oxidation and decreased fatty acid esterification ... Our
findings suggest that dietary curcumin may have a potential benefit in
preventing obesity" - See

Green Tea
(-)-Epigallocatechin-3-Gallate Reduces Body Weight with Regulation of Multiple
Genes Expression in Adipose Tissue of Diet-Induced Obese Mice - Ann Nutr
Metab. 2009 Apr 22;54(2):151-157 - "Experimental diets
supplemented with EGCG resulted in reduction of body weight and mass of various
adipose tissues in a dose-dependent manner. EGCG diet also considerably lowered
the levels of plasma triglyceride and liver lipid. In the epididymal white
adipose tissue of EGCG diet-fed mice, the mRNA levels of adipogenic genes such
as peroxisome proliferator-activated receptor-gamma (PPAR-gamma), CCAAT
enhancer-binding protein-alpha (C/EBP-alpha), regulatory element-binding
protein-1c (SREBP-1c), adipocyte fatty acid-binding protein (aP2), lipoprotein
lipase (LPL) and fatty acid synthase (FAS) were significantly decreased.
However, the mRNA levels of carnitine palmitoyl transferase-1 (CPT-1) and
uncoupling protein 2 (UCP2), as well as lipolytic genes such as hormone
sensitive lipase (HSL) and adipose triglyceride lipase (ATGL), were
significantly increased ... These results suggest that green tea EGCG
effectively reduces adipose tissue mass and ameliorates plasma lipid profiles in
high-fat diet-induced obese mice. These effects might be at least partially
mediated via regulation of the expression of multiple genes involved in
adipogenesis, lipolysis, beta-oxidation and thermogenesis in white adipose
tissue" - See

How much physical activity is enough to prevent unhealthy weight gain?
- Obes Rev 2003 May;4(2):101-14 - "The following
consensus statement was accepted unanimously. 'The current physical activity
guideline for adults of 30 minutes of moderate intensity activity daily,
preferably all days of the week, is of importance for limiting health risks
for a number of chronic diseases including coronary heart disease and
diabetes. However for preventing weight gain or regain this guideline is
likely to be insufficient for many individuals in the current environment.
There is compelling evidence that prevention of weight regain in formerly
obese individuals requires 60-90 minutes of moderate intensity activity or
lesser amounts of vigorous intensity activity. Although definitive data are
lacking, it seems likely that moderate intensity activity of approximately
45 to 60 minutes per day, or 1.7 PAL (Physical Activity Level) is required
to prevent the transition to overweight or obesity. For children, even more
activity time is recommended. A good approach for many individuals to obtain
the recommended level of physical activity is to reduce sedentary behaviour
by incorporating more incidental and leisure-time activity into the daily
routine"
