How Our Calculator Works
Estimates based on standard nutrition formulas and user inputs. Results are approximate.
TDEE Calculation
This calculator estimates calorie needs using the Mifflin-St Jeor formula and activity level based on total energy burns each day.
Protein Estimation
Protein amount is based on body weight and fitness goal. It helps muscle recovery, supports growth, and protects muscle during fat loss.
Calorie Adjustment
Calories are adjusted based on your goal like fat loss, maintenance, or muscle gain using small deficit or surplus for better body results.
Macro Breakdown
After setting calories, the calculator splits them into protein, carbs, and fats to support energy and muscle repair for daily performance.
Frequently Asked Questions
Answers to common questions about body recomposition, calorie targets, and results.
Different tools use different formulas and activity levels, so results are not always same, but this gives a good starting idea for daily calories.
Yes, body recomposition is possible when you eat near maintenance calories, eat enough protein, and do regular strength training.
Because you may lose fat and gain muscle at the same time, so body shape improves but weight on scale can stay same.
No need to change every week. Wait for 2–3 weeks and check your real progress before making any changes.
It is an estimate, not exact. Every person has different body, lifestyle, and activity, so results can be slightly different.
Yes, beginners often see faster results because their body responds quickly to new training and better eating habits.
Gym helps, but you can also do body recomposition with home workouts like push-ups, squats, and simple strength training.
You need enough protein every day to help your muscles grow and recover, especially when trying body recomposition.
Because active people burn more energy, so their daily calorie need becomes higher than less active people.
It takes time. You need patience, good food, and regular exercise for slow but steady body changes.
