Whey

Specific Recommendations:

News & Research:

  • Whey beneficially affects diabetes and cardiovascular disease risk factors in obese adults - Science Daily, 4/30/14 - "They gave volunteers who were obese and non-diabetic the same meal of soup and bread plus one kind of protein, either from whey, gluten, casein (another milk protein) or cod. The scientists found that the meal supplemented with whey caused the subjects' stomachs to empty slower than the others'. These subjects also had lower levels of fatty acids in their blood after meals but higher amounts of the specific types of amino acids that boost insulin levels" - See whey protein at Amazon.com.
  • Effects of Soy, Whey Protein Supplementation Post-Exercise - Science Daily, 10/12/13 - "Our main findings demonstrate that 14 days of supplementation with soy protein does appear to partially blunt serum testosterone. In addition, whey influences the response of cortisol following an acute bout of resistance exercise by blunting its increase during recovery"
  • 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. Women who ate more protein lost 3.9 percent more weight and had a relative gain of 5.8 percent more thigh muscle volume than woman who did not ... 31 healthy, postmenopausal obese women were divided into two groups. Each group followed a 1,400-calorie weight-loss diet based on USDA's My Pyramid, but one group received a powdered whey protein supplement in the morning and again in the afternoon or evening; the other received a placebo that contained carbohydrates ... We hypothesize that more vigorous exercise -- in particular, resistance training -- would preserve even more muscle" - See whey protein at Amazon.com or try the yogurt recipe at the top of 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"
  • Whey protein may cut metabolic risk of high-fat diet: Mouse study - Nutra USA, 3/24/11
  • Whey protein holds fat fighting potential, suggests study - Nutra USA, 2/3/11 - "The amount of fat inside liver cells (known as intra-hepatocellular lipid concentrations – IHCL) in subjects fed a short term high fat diet has been previously shown to be reduced again through increasing dietary protein intake ... four weeks of supplementation with whey protein led to a significant decrease in IHCL of 21 percent, whilst fasting plasma triglyceride was observed to decrease by 15 percent, and total plasma cholesterol concentration decreased by over 7 percent" - [Abstract]
  • Whey supplements lower blood pressure: Low-cost protein gets big results in people with elevated blood pressure - Science Daily, 12/8/10 - "Beverages supplemented by whey-based protein can significantly reduce elevated blood pressure, reducing the risk of stroke and heart disease ... daily doses of commonly available whey brought a more than six-point reduction in the average blood pressure of men and women with elevated systolic and diastolic blood pressures ... blood-pressure reductions like those seen by Fluegel can reduce cardiovascular disease and bring a 35 to 40 percent reduction in fatal strokes"
  • Whey protein better than meat for reducing body weight - Nutra USA, 6/7/04 - "Increasing the dietary density of whey protein, but not of red meat, reduced body weight gain by 4 per cent, they add, while whey protein also reduced plasma insulin concentration by 40 per cent and increased insulin sensitivity, compared to meat protein"
  • Athletes Believe The "Whey" To Greater Muscle Strength Is Through Training And Protein Supplements - Intelihealth, 4/10/03 - "supplementation with a100% whey isolate formulation and creatine produced greater muscle fiber growth increases that transferred into significant increases in functional strength"
  • The New Faces Of Whey - Life Extension Magazine, 1/02 - "whey may be able to reduce stress and depression by lowering cortisol and increasing brain serotonin, improve liver function (in those suffering from certain forms of hepatitis) and reduce blood pressure"

Ten weeks of both TCTs and WPIs increased exercise endurance by 50% in sedentary, diet-induced obese rats" - [Nutra USA] - See whey protein at Amazon.com and Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.
  • Combined Oral Intake of GABA with Whey Protein Improves Lean Mass in Resistance-trained Men - Med Sci Sports Exerc. 2016 May;48(5 Suppl 1):54 - "After 12 wk, change in whole body lean mass was significantly higher in the WP+G group compared to the WP group (1340 +/- 465 vs. 146 +/- 218 g." - [Nutra USA] - See GABA at Amazon.com.  GABA is part of my sleep cocktail.  I'm sticking with leucine for the protein part.
  • Two-Year Whey Protein Supplementation Did Not Enhance Muscle Mass and Physical Function in Well-Nourished Healthy Older Postmenopausal Women - J Nutr. 2015 Sep 23 - "in protein-replete healthy ambulant postmenopausal women, 30 g/d of extra protein did not improve the maintenance of muscle mass or physical function despite evidence of deterioration in muscle measurements in the upper limb"
  • Effects of whey protein and resistance exercise on body composition: a meta-analysis of randomized controlled trials - J Am Coll Nutr. 2014 Apr;33(2):163-75 - "A comprehensive literature search was conducted to identify RCTs that investigated WP (concentrate, isolate, or hydrolystate) and body weight, body mass index (BMI), body fat, lean body mass (LBM), fat-free mass (FFM), and waist circumference ... Body weight (WGMD: -4.20 kg, 95% confidence interval [CI], -7.67, -0.73) and body fat (WGMD: -3.74 kg, 95% CI, -5.98, -1.50) were significantly decreased from baseline in the WPR within-group analyses ... Results from the subgroup analyses indicated a statistically significant increase in LBM (WGMD: 2.24 kg, 95% CI, 0.66, 3.81) among studies that included a resistance exercise component along with WP provision" - Note: 4.20 kg is 9.3 pounds.  See whey protein at Amazon.com.
  • Leucine supplementation of a low-protein mixed macronutrient beverage enhances myofibrillar protein synthesis in young men: a double-blind, randomized trial - Am J Clin Nutr. 2013 Nov 27 - "myofibrillar protein synthesis (MPS) ... A low-protein (6.25 g) mixed macronutrient beverage can be as effective as a high-protein dose (25 g) at stimulating increased MPS rates when supplemented with a high (5.0 g total leucine) amount of leucine. These results have important implications for formulations of protein beverages designed to enhance muscle anabolism" - [Nutra USA] - Note:  That's about what I take per day in the one heaping scoop.  It's got to be the worst tasting substance in the world.  I put the scoop in a small jar with about a third cup of water, shake it and swill in then rinse the jar a couple more times to get it all.  See leucine products at Amazon.com.
  • Myofibrillar muscle protein synthesis rates subsequent to a meal in response to increasing doses of whey protein at rest and after resistance exercise - Am J Clin Nutr. 2013 Nov 20 - "muscle protein synthesis (MPS) ... A 20-g dose of whey protein is sufficient for the maximal stimulation of postabsorptive rates of myofibrillar MPS in rested and exercised muscle of ~80-kg resistance-trained, young men. A dose of whey protein >20 g stimulates amino acid oxidation and ureagenesis" - See whey protein at Amazon.com.
  • The effects of soy and whey protein supplementation on acute hormonal reponses to resistance exercise in men - J Am Coll Nutr. 2013 Feb;32(1):66-74 - "For many resistance-trained men concerns exist regarding the production of estrogen with the consumption of soy protein when training for muscle strength and size. Thus, the purpose of this investigation was to examine the effects of soy and whey protein supplementation on sex hormones following an acute bout of heavy resistance exercise in resistance trained men ... Ten resistance-trained men (age 21.7 +/- 2.8 [SD] years; height 175.0 +/- 5.4 cm; weight 84.2 +/- 9.1 kg) volunteered to participate in an investigation ... all subjects completed 3 experimental treatment conditions supplementing with whey protein isolate (WPI), soy protein isolate (SPI), and maltodextrin placebo control for 14 days with participants ingesting 20 g of their assigned supplement each morning at approximately the same time each day ... This investigation observed lower testosterone responses following supplementation with soy protein in addition to a positive blunted cortisol response with the use of whey protein at some recovery time points. Although sex hormone binding globulin (SHBG) was proposed as a possible mechanism for understanding changes in androgen content, SHBG did not differ between experimental treatments. Importantly, there were no significant differences between groups in changes in estradiol concentrations"
  • Whey protein supplementation during resistance training augments lean body mass - J Am Coll Nutr. 2013 Apr;32(2):122-35 - "Compared to soy, whey protein is higher in leucine, absorbed quicker and results in a more pronounced increase in muscle protein synthesis ... randomized non-resistance-trained men and women into groups who consumed daily isocaloric supplements containing carbohydrate (carb; n = 22), whey protein (whey; n = 19), or soy protein (soy; n = 22) ... Lean body mass gains were significantly (p < 0.05) greater in whey (3.3 +/- 1.5 kg) than carb (2.3 +/- 1.7 kg) and soy (1.8 +/- 1.6 kg). Fat mass decreased slightly but there were no differences between groups. Fasting concentrations of leucine were significantly elevated (20%) and postexercise plasma leucine increased more than 2-fold in whey. Fasting leucine concentrations were positively correlated with lean body mass responses"
  • A Whey Protein Hydrolysate Promotes Insulinotropic Activity in a Clonal Pancreatic β-Cell Line and Enhances Glycemic Function in ob/ob Mice - J Nutr. 2013 May 8 - "In conclusion, an 8-wk oral administration of WPH improved blood glucose clearance, reduced hyperinsulinemia, and restored the pancreatic islet capacity to secrete insulin in response to glucose in ob/ob mice. Hence, it may be useful in diabetes management"
  • Post-exercise whey protein hydrolysate supplementation induces a greater increase in muscle protein synthesis than its constituent amino acid content - Br J Nutr. 2013 Feb 7:1-7 - "Male Sprague-Dawley rats swam for 2 h to depress muscle protein synthesis. Immediately after exercise, the animals were administered either carbohydrate (CHO), CHO plus an amino acid mixture (AA) or CHO plus WPH. At 1 h after exercise, the supplements containing whey-based protein (AA and WPH) caused a significant increase in the fractional rate of protein synthesis (FSR) compared with CHO ... These results indicate that WPH may include active components that are superior to amino acids for stimulating muscle protein synthesis and initiating translation" - See whey protein at Amazon.com.
  • Similar effects of leucine rich and regular dairy products on muscle mass and functions of older polymyalgia rheumatica patients: a randomized crossover trial - J Nutr Health Aging. 2011;15(6):462-7 - "Patients performed as many stand ups as possible twice a day after which they ingested a regular (Control) or a whey protein enriched dairy product with high leucine content (Test). The 8-week intervention periods were separated by a 4-week wash-out ... The 16-week home-based post-exercise supplementation resulted in a 1.8% increase (p = 0.052) in lower limb muscle mass. Walking speed (+5.3%, p = 0.007) and chair stand test performance (-12.2 %, p < 0.001) were also improved. Furthermore, a tendency for increased jump power (+3.0%, p = 0.084) was observed. However, significant and consistent differences were not found in the changes of muscle mass indices or muscle functions between supplements, but the test supplement tended to prevent accumulation of body fat. Conclusion: A low intensity home based exercise program combined with post-exercise milk protein supplementation is feasible despite some gastrointestinal complaints and seems effective in improving the muscle mass and functions of older persons with a inflammatory disease. Further studies are needed to establish, whether and to what extent the use of leucine-enriched whey products prevent or treat age-associated sarcopenia and whether they are superior to the present commercial milk products"
  • Protective effect of whey proteins against nonalcoholic fatty liver in rats Lipids Health Dis. 2011 Apr 13;10(1):57 - "Oral administration of the studied whey proteins products reduced the final body weight of rats. There was a significant reduction effect (P<0.05) of the tested proteins on hepatic triglycerides, liver enzymes (ALT and AST), lipid peroxidation (malondialdehyde level) and serum glucose. Feeding on whey proteins caused an increase in the reduced glutathione. Hepatic content of reduced glutathione was not affected by any of the used whey proteins, but it showed an increasing tendency (P>0.05). Liver histology showed an improvement of fatty infiltration in hepatocytes from whey protein groups and gives the histology of liver a normal appearance"
  • Dietary Whey Protein Lowers the Risk for Metabolic Disease in Mice Fed a High-Fat Diet - J Nutr. 2011 Feb 10 - "whey protein isolate (WPI) ... Livers from WPI mice had significantly fewer hepatic lipid droplet numbers and less deposition of nonpolar lipids. Furthermore, WPI improved glucose tolerance and insulin sensitivity. We conclude that in mice receiving a HF diet, consumption of WPI results in higher basal metabolic rates and altered metabolism of dietary lipids. Because WPI mice had less hepatosteatosis and insulin resistance, WPI dietary supplements may be effective in slowing the development of fatty liver disease and type 2 diabetes"
  • Effects of a whey protein supplementation on intrahepatocellular lipids in obese female patients - Clin Nutr. 2011 Jan 31 - "intrahepatocellular lipids (IHCL) ... 60 g/day whey protein supplement (WPS) for 4-weeks ... total liver volume (MR) ... IHCL were positively correlated with visceral fat and total liver volume at inclusion. WPS decreased significantly IHCL by 20.8 +/- 7.7%, fasting total TG by 15 +/- 6.9%, and total cholesterol by 7.3 +/- 2.7%. WPS slightly increased fat free mass from 54.8 +/- 2.2 kg to 56.7 +/- 2.5 kg, p = 0.005). Visceral fat, total liver volume, glucose tolerance, creatinine clearance and insulin sensitivity were not changed"
