Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Despite the importance of preventing muscle mass loss during senescence, only a few studies have investigated the relationship between diet and muscle mass in postmenopausal women. Therefore, the aim of this study is to investigate whether controlled protein consumption at the current Recommended Daily Allowance (RDA = 0.8 g/kg body weight) or twice the RDA (1.6 g/kg body weight) affects skeletal muscle mass, strength, and physical performance in postmenopausal women. In this parallel-group trial, participants were randomized for 6 months to low glycemic index diets with controlled protein consumption at the current RDA or twice the RDA, aimed to balance energy needs.
