Brief summary
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.
Detailed description
In this study, three arms will be studied for 3 months: 1 control group, 1 group with whey supplementation at lunch, and 1 group with whey supplementation at lunch and an energy bolus before bedtime. Actions include weight and body composition monitoring, nutritional status and muscle function, as well as mechanistic.
Interventions
In addition to their normal meal, patients will eat 30g of whey protein every lunch during 90 days.
In addition to their normal meal, patients will eat 30g of whey protein every lunch during 90 days and eat 60g of carbohydrates 2h after every diner during 90 days.
