How Body Recomposition Works

Body recomposition uses calorie cycling - eating more on training days when your body needs fuel for muscle building, and less on rest days to encourage fat loss.

Key to Success: Keep protein high every day (around 1g per pound of body weight), train with progressive overload, and get enough sleep. Results are slower than traditional bulk/cut cycles, but you stay leaner year-round.

Best candidates: Beginners, people returning after a break, those with higher body fat, or anyone wanting to improve body composition without gaining weight.

Reference: Calorie cycling approach based on research on nutrient timing and energy balance. Individual results vary based on training experience and body composition.
