How This Calculation Works

Body recomposition requires precision: slight caloric deficit or maintenance, combined with high protein intake (2.0–2.4g/kg) and progressive overload training.

Dynamic High-Protein Ratio: Scaled specifically by bodyweight to prevent lean muscle cannibalization during caloric deficit phases.
Mifflin-St Jeor Accuracy: Internationally validated formula accounting for sex, height, weight, and specific activity factors.

Frequently Asked Questions

Can you really build muscle and lose fat at the same time?

Yes. Known as body recomposition, it is most effective for beginners, individuals returning from a layoff, or those with higher body fat percentages who consume adequate protein.

What is the recommended protein intake for recomposition?

Research suggests 1.0 to 1.2 grams per pound of body weight (2.2–2.6g per kg) to support muscle protein synthesis in a slight deficit.
