Whey Protein لـ Muscle Preservation During Weight Loss

A

Meta-analysis of 14 RCTs (n=626) found whey protein preserved lean mass while reducing fat mass (1.49 kg) and waist circumference (1.32 cm) during caloric restriction. High leucine content maximally stimulates mTOR-mediated muscle protein synthesis.
