Body Recomposition Macro Calculator

Achieving a leaner, stronger physique requires more than just tracking weight — it demands proper nutrition tailored to your body composition goals. The Body Recomposition Macro Calculator helps you calculate your ideal daily intake of protein, fats, and carbohydrates based on your personal data, activity level, and training schedule.

By adjusting your macros on training and rest days, this tool supports efficient fat loss while preserving or building muscle — the cornerstone of body recomposition.

How Does the Body Recomposition Macro Calculator Work?

This calculator takes several inputs to personalize your macro goals:

  • Gender: Male or Female (influences metabolism)
  • Age: Your age in years
  • Weight: Body weight in pounds
  • Height: Height in inches
  • Body Fat Percentage: Current fat percentage
  • Activity Level: Sedentary to extremely active multiplier
  • Training Days: Number of workout days per week
  • Recomp Approach: Choose from Standard, Calorie Cycling, or Aggressive Cut

Based on these, it calculates:

  • Lean Body Mass (LBM): Weight minus fat mass
  • Basal Metabolic Rate (BMR): Calories burned at rest
  • Total Daily Energy Expenditure (TDEE): Calories burned including activity
  • Training Day Calories: Calories for workout days
  • Rest Day Calories: Calories for rest days
  • Macros: Daily protein (grams and calories), fats, and carbohydrates for training and rest days

How to Use the Body Recomposition Macro Calculator

  1. Select your gender.
  2. Enter your age, weight, and height.
  3. Provide your current body fat percentage.
  4. Choose your activity level based on your lifestyle.
  5. Input your training days per week (0-7).
  6. Select your preferred recomp approach:
    • Standard Recomp: Consistent calorie intake with moderate deficit
    • Calorie Cycling: Higher calories on training days, lower on rest days
    • Aggressive Cut: Larger calorie deficit focused on fat loss
  7. Click Calculate to get your personalized macros and calories for training and rest days.
  8. Use Reset to clear inputs and start fresh.

Example Calculation

A 28-year-old female weighing 140 lbs, 65 inches tall, with 25% body fat, lightly active (1-3 days/week), training 4 days a week, wants to follow a calorie cycling approach.

  • Lean Body Mass = 140 × (1 - 0.25) = 105 lbs
  • BMR (female formula) ≈ 655 + (4.35 × 140) + (4.7 × 65) - (4.7 × 28) = ~1399 cal
  • TDEE = 1399 × 1.375 (lightly active) = ~1924 cal
  • Training Day Calories = TDEE + 100 = 2024 cal
  • Rest Day Calories = TDEE - 300 = 1624 cal
  • Protein = 105 × 1.1 = 116 g (464 cal) daily
  • Training Fat = 25% of training calories = 506 cal / 9 = 56 g fat
  • Training Carbs = Remaining calories after protein & fat: (2024 - 464 - 506) / 4 = 263 g carbs
  • Rest Fat = 35% of rest calories = 568 cal / 9 = 63 g fat
  • Rest Carbs = (1624 - 464 - 568) / 4 = 148 g carbs

Why Use This Macro Calculator?

  • Precision: Personalized macros help you fuel workouts and recovery properly.
  • Adaptability: Calorie cycling allows flexible intake for training vs rest days.
  • Muscle Preservation: Adequate protein intake supports muscle retention during fat loss.
  • Goal-Oriented: Choose the approach that matches your recomposition strategy.
  • Convenience: Easy-to-use tool removes guesswork from nutrition planning.

Frequently Asked Questions (FAQs)

1. What is calorie cycling?
Calorie cycling involves eating more calories on training days and fewer on rest days to optimize fat loss and muscle gain.

2. How is protein calculated?
Protein is set at 1.1 grams per pound of lean body mass for optimal muscle maintenance.

3. Why do fats and carbs vary between training and rest days?
Fats are typically higher on rest days to support recovery, carbs higher on training days to fuel workouts.

4. Can I use this calculator if I’m not training regularly?
Yes, just input your actual training days; the calculator adjusts accordingly.

5. What is the aggressive cut approach?
A calorie deficit strategy for faster fat loss, with reduced calories on all days.

6. Why is activity level important?
Activity level helps estimate your total daily energy needs beyond resting metabolism.

7. Can I trust the calorie estimates?
They are estimates based on standard formulas; individual needs may vary.

8. How often should I update my inputs?
Update when your weight, body fat, or activity level changes significantly.

9. What units does the calculator use?
Weight and protein in pounds and grams, height in inches, calories in kcal.

10. Does this calculator replace a dietitian’s advice?
It’s a helpful starting point but doesn’t replace personalized professional guidance.

11. How should I track progress?
Regularly measure weight, body fat, and strength to adjust macros accordingly.

12. Can I combine this with supplements?
Yes, but macros focus on whole food intake primarily.

13. What if my body fat percentage is estimated inaccurately?
Use the best measurement available for accurate results.

14. How do carbs affect recomposition?
Carbs provide energy for workouts and recovery, especially on training days.

15. Is this calculator suitable for beginners?
Yes, it’s designed for users of all levels seeking body recomposition.
