摘要

use of a composition; and method for conserving muscle mass or stimulating muscle mass increase or reducing the risk of sarcopenia in obese or overweight adults at least 40 years of age participating in a weight loss program the present invention relates to use of a composition comprising, per portion, between 50 - 300 kcal; between 10 g and 35 g of proteinaceous matter; and at least 2.5 micrograms of vitamin d for the manufacture of a nutritional product for (a) treating or preventing lean muscle mass, (b) stimulating lean muscle mass; or (d) stimulation of muscle mass conservation in obese or overweight adults at least 40 years old participating in a weight loss program. The inventors surprisingly found that nutritional supplementation with a protein-rich, low-calorie composition, particularly whey and leucine protein, compared to a protein-free isocaloric control supplement, leads synergistically to the conservation of muscle mass during a weight loss program. involving a low-calorie diet and an overweight / obese older adult endurance exercise program.
