Macro partitioning

Post-starvation refeeding with a restricted diet (800 cal) leads to rapid reaccumulation of lean tissue (water and protein) while continuing to lose fat, resulting in a net fat loss rate higher than during the starvation phase itself.

After a period of fasting, do not binge. Return to a moderate calorie deficit (e.g., 800 calories). This study shows that your body will rapidly restore water and muscle mass while burning fat at a rate higher than during the fast itself. The 'rebound' is actually a fat-burning advantage if you maintain the deficit.

During poststarvation caloric restriction, there was gain in weight, considerable reaccumulation of lean tissue, and loss of fat at a rate that was substantially greater than that during starvation.

Why this rating

Small sample size, but the trend is consistent across both studies.
