Whey Protein Twice a Day Keeps Muscle Loss Away

There’s a big difference between “good” and “bad” weight loss. The good
kind, the kind we should all strive for, is losing the least amount of
muscle in relation to body fat.



Getting enough protein is one of the keys to preserving the most muscle
while dieting, but research shows protein may be lacking in a lot of
weight loss diets, considering that on average the amount of weight loss
most people have is about 30 percent from muscle.



A matter of hot debate has been whether the source of protein, be it animal or plant, could
be an important factor in saving muscle while losing weight. Some of
early research has shown, for example, that dairy proteins such as whey
have been able to lead to greater fat loss while maintaining muscle.



Now a new randomized, double-blinded study has shown that whey protein
supplementation can further help preserve more muscle compared to soy or
carbohydrate (1). The study was published in December in the Journal of Nutrition by researchers from McMaster University in Ontario, Canada.



The 14-day weight-loss study randomized overweight or obese men and
women to groups consuming prepackaged diets containing whey (27 grams),
soy (26 grams), or carbohydrate (25 grams) twice daily. All of the
groups lost some weight including from body fat and muscle with no
significant differences.



However, the researchers found that the group that consumed whey showed
greater muscle protein synthesis (MPS) compared to subjects consuming
either soy or carbohydrate. Moreover, the carbohydrate group had less
fat breakdown compared to the group consuming whey or soy.



In the conclusion, the study authors wrote, whey protein slowed the
decline of MPS as a result of weight loss and could be an important
factor in preserving muscle in long-term weight loss.



Lead researcher Stuart Phillips, Ph.D., interviewed for this blog previously,
has often noted the critical importance of maintaining muscle over time
since it can play a role not only in resting metabolism, but also for
supporting blood sugar control and overall mobility.



Whey can be a useful protein because of its high content of
branched-chain amino acids (namely leucine) that helps to promote muscle
protein synthesis in comparison to other protein sources, Phillips
said.



The dose of whey needed to maximize muscle depends on age and amount of resistance training too.



For instance, in previous research conducted by Phillips and others, it
was found that adults (20 to 65) and elderly men (65 and above)
exhibited a differential response to varying amounts of whey protein
after resistance training (2). For men under 65, whey protein in
amounts of 20 grams at each meal was able to maximally stimulate muscle
protein synthesis, whereas elderly individuals required double the dose,
35 to 40 grams, to obtain the same response.



The reason has to do with a blunted anabolic response to protein
ingestion that occurs in people with age as they become more sedentary,
which is why Phillips recommends getting some form of physical activity
every day.



Regular resistance training of muscles in combination with obtaining
quality sources of protein such as whey regularly is the key to
maintaining muscle during weight loss, according to Phillips.
