In this study, we aimed to examine the effect of whey protein supplementation given before night sleep on Fat Free Mass (FFM) preservation during a 4 wk period on Very Low Caloric Diet (VLCD). Half of the participants underwent a 4 week VLCD and walking program, while the other half underwent a 4 week VLCD, walking program and had an additional protein supplement before each night sleep.
