Research Inconclusive As To Whether Diet, Exercise May Prevent Age-Related Muscle Loss.

People lose 30 percent to 50 percent of their muscle mass between the ages of 40 and 80, according to the study authors. Although some studies have found enhanced effects of exercise training when combined with diet supplementation, our review shows that current evidence is incomplete and inconsistent. Further research to determine the benefits of supplementation and exercise training for older people is therefore needed," Robinson said.
