Optimization of the Preservation of Muscle Mass and / or Its Recovery by a Protein-energy Chrononutrition Approach Dissociated From Meals

Muscle wasting has a multifactorial origin, including decreased physical activity, malnutrition, loss of post-incident muscle recovery abilities, and decreased ability to regenerate muscle. Among the strategies tested to improve the production of proteins and thus muscle is the supplementation of whey proteins. However this strategy does not seem sufficient and optimal to avoid muscle wasting and it must be complemented by a complementary action. Muscle protein degradation also occurs during the nocturnal fasting periods to provide amino acids for energy purposes and to produce glucose, essential for vital organs. The preservation of the benefit of whey intake during meals could therefore be optimized by reducing the use of muscle proteins for energy purposes during the night.
