How Body Recomposition Calculator is Calculated

Frequently Asked Questions
Can you really lose fat and build muscle at the same time?
Yes, especially for beginners, overweight individuals, and those returning after a break. It requires high protein (2g/kg), resistance training 3–4x/week, and calorie cycling. Progress is slower than a dedicated bulk or cut.
What macro split works for body recomp?
Protein: 2–2.4g/kg (highest priority). Training days: maintenance + 200 cal, 40% protein/30% carbs/30% fat. Rest days: maintenance − 400 cal, 45% protein/25% carbs/30% fat.
