Efficacy of 2.8 g/kg/day protein to prevent lean mass loss during weight maintenance is uncertain

Determine whether consuming approximately 2.8 g of protein per kilogram of body weight per day prevents additional lean mass loss during weight maintenance following an energy‑restricted period in active young adults.

Background

Findings in active students under energy restriction indicated lean mass loss despite high protein intake, and it is not established whether very high protein intake would mitigate losses during subsequent weight maintenance.
