Body Recomposition Calculator

Body recomposition means reducing body fat while maintaining or building muscle over time, usually by staying near maintenance calories with strong training and high protein.

Bulking prioritizes muscle gain with a larger surplus, and cutting prioritizes fat loss with a deeper deficit. Recomposition aims for slower, more balanced progress between both goals.

Use a small deficit if fat loss is the priority, maintenance for balanced recomposition, and a small surplus if performance and muscle gain are the main focus.

Most people do well around 1.6 to 2.4 g of protein per kg body weight per day. The calculator provides a strong starting target you can keep consistent while adjusting calories.

No. Keep protein consistent first, then stay close to total calories. Carbs and fats can flex based on training days, appetite, and food preference.

It is an estimate, not a perfect measurement. Your real needs depend on factors like NEAT, training volume, sleep, stress, and tracking consistency.

Run it for about 2 to 3 weeks first, then adjust by roughly 100 to 150 kcal if weekly trend data shows progress is too slow or too fast for your goal.

Usually yes. Beginners and people returning after a break often see faster recomposition than advanced lifters, who generally need smaller, more precise adjustments.

Recomposition is usually slower than dedicated bulk or cut phases. Many people aim for roughly 0 to 0.5% body-weight change per week depending on goal focus.

That can still be good progress. Use multiple signals: photos, waist measurements, gym performance, and weekly average body weight, not scale weight alone.

Yes. Cardio can support fitness and energy expenditure, but keep resistance training as the priority and avoid adding so much cardio that recovery or performance drops.

Recalculate when body weight changes meaningfully, activity level shifts, or training volume changes. Many people refresh targets every 4 to 8 weeks.

Yes. The calculator already accounts for sex in the BMR estimate. The same recomposition principles apply: progressive training, high protein, and trend-based calorie adjustments.

Increase calories slightly, prioritize protein and fiber-rich meals, and check sleep and hydration. Recomposition works best when the plan is sustainable and recovery stays strong.

Switch when your primary goal becomes speed over balance. If you need faster fat loss or faster muscle gain, a dedicated phase is often more efficient.
