Body Recomposition Calorie Calculator
Body recomposition is all about losing fat while maintaining or building lean muscle. Unlike standard dieting, which focuses solely on weight, recomposition emphasizes body composition—fat percentage versus lean body mass.
Our Body Recomposition Calorie Calculator helps you determine your daily calorie needs and macronutrient breakdown based on your age, gender, weight, height, activity level, and recomposition goal. This tool gives practical numbers for protein, carbs, fats, and calorie targets to guide your diet and training effectively.
Whether your goal is a moderate recomp, aggressive fat loss, or simply maintaining your current weight, this calculator provides accurate, actionable numbers to support your fitness journey.
How the Calculator Works
The calculator uses established formulas to determine:
- BMR (Basal Metabolic Rate): Calories your body burns at rest
- TDEE (Total Daily Energy Expenditure): Calories to maintain current weight based on activity level
- Calorie Target: Adjusted calories according to your recomp goal (aggressive, moderate, conservative, or maintenance)
- Macro Breakdown: Daily grams of protein, carbohydrates, and fats for optimal recomposition
- Training vs Rest Days: Adjusted calories to support workouts and recovery
By integrating all these factors, you get a personalized nutrition plan for effective fat loss and muscle preservation.
How to Use the Body Recomposition Calorie Calculator
Step-by-Step Guide
- Select Gender
Choose male or female for accurate metabolic calculations. - Enter Age
Your age influences basal metabolism. - Enter Current Weight (lbs)
The calculator uses this to determine daily caloric requirements. - Enter Height (Feet & Inches)
Height is essential for calculating your BMR. - Optional: Body Fat Percentage
If known, body fat helps refine protein and macro recommendations. Otherwise, the calculator estimates lean mass. - Select Activity Level
Ranges from sedentary to extremely active. This adjusts TDEE. - Choose Recomp Goal
- Aggressive Cut (-20%)
- Moderate Recomp (-10%)
- Conservative Recomp (-5%)
- Maintenance (0%)
- Click Calculate
View personalized daily calories, macros, and training/rest day targets instantly.
Example Calculation
Scenario:
- Gender: Female
- Age: 28
- Weight: 150 lbs
- Height: 5 ft 5 in
- Body Fat: 25%
- Activity Level: Moderately Active
- Recomp Goal: Moderate (-10%)
Results You’ll See:
- BMR: ~1,430 calories
- TDEE: ~2,200 calories
- Daily Calorie Target: ~1,980 calories
- Protein: ~112g
- Carbs: ~220g
- Fats: ~52g
- Training Days Calories: ~2,180 calories
- Rest Days Calories: ~1,780 calories
This gives a balanced daily plan for losing fat while preserving lean muscle.
What Each Result Means
BMR (Basal Metabolic Rate)
Calories your body burns at rest to maintain essential functions.
TDEE (Total Daily Energy Expenditure)
Calories required to maintain weight considering your daily activity level.
Daily Calorie Target
Calories adjusted for your chosen recomposition goal, ensuring fat loss without sacrificing muscle.
Protein
Daily grams required to support muscle retention. Protein intake is calculated based on lean body mass.
Carbohydrates
Fuel for workouts and daily activity. Carbs are adjusted according to calorie target.
Fats
Essential for hormone production and recovery, calculated proportionally.
Training vs Rest Day Calories
Higher calories on training days support performance, lower calories on rest days aid fat loss while promoting recovery.

Frequently Asked Questions (FAQs)
1. What is a body recomposition calorie calculator?
It calculates daily calories and macronutrients for fat loss while maintaining or gaining lean muscle.
2. Do I need to know my body fat percentage?
Not required, but including it improves protein and macro accuracy.
3. Can men and women use it?
Yes, calculations adjust based on gender.
4. What is TDEE?
Total Daily Energy Expenditure—the calories needed to maintain current weight with activity.
5. Why are training and rest day calories different?
Training days require more energy to fuel workouts, rest days require fewer calories.
6. What is a moderate recomp goal?
A moderate recomp reduces calories slightly (~10%) for sustainable fat loss while preserving muscle.
7. How do I know which goal to choose?
Aggressive cuts are faster but harder to maintain, moderate is balanced, conservative is safest.
8. Can I gain muscle while cutting fat?
Yes, especially with adequate protein intake and resistance training.
9. How often should I recalculate?
Every 3–4 weeks, or after significant changes in weight or activity.
10. Are the results guaranteed?
Numbers are estimates. Real results depend on diet adherence, exercise, and consistency.
11. How do I track progress?
Use weight, body fat measurements, photos, and strength improvements.
12. Is this calculator suitable for beginners?
Yes, it’s simple and easy to use for anyone starting a recomposition plan.
13. Can athletes use this?
Yes, the calculator works for all activity levels and goals.
14. What happens if I skip the body fat input?
The calculator will assume average lean mass for protein calculation.
15. Can I adjust macros manually?
Yes, you can tweak protein, carbs, and fats based on personal preference while keeping calories consistent.
Conclusion
The Body Recomposition Calorie Calculator empowers you to create a personalized, actionable plan for fat loss and muscle retention. By understanding calories, macros, and training vs rest day needs, you can approach recomposition with confidence, precision, and sustainable results.
