About Body Recomp Calculator
A free online tool that helps fitness enthusiasts calculate their optimal calorie and macro targets for body recomposition.
Our Mission
We created this calculator to demystify body recomposition nutrition. Our goal is to provide a science-based starting point for anyone looking to improve their body composition without extreme dieting phases.
The Science
We use the Mifflin-St Jeor equation to estimate BMR, considered more accurate than older formulas. Macro recommendations are based on current sports nutrition research with high protein for muscle synthesis.
Limitations
Metabolic rate varies between individuals. Activity level is self-reported. Results should be adjusted based on actual progress. Stress, sleep, and medications also affect metabolism.
Why We're Free
Everyone deserves access to basic nutrition guidance without paywalls. Our calculator requires no registration and doesn't store personal data. All calculations happen locally in your browser.
