Bodybuilding Fat Loss Formula:
From: | To: |
This calculator helps bodybuilders and fitness enthusiasts determine their optimal calorie and protein intake for effective fat loss while preserving muscle mass. It uses scientifically-backed formulas tailored for bodybuilding goals.
The calculator uses two key formulas:
Where:
Explanation: The 500 kcal deficit creates about 1 pound (0.45 kg) of fat loss per week, while the high protein intake helps maintain muscle mass.
Details: A controlled 500 kcal deficit balances effective fat loss with muscle preservation. Larger deficits may cause muscle loss, while smaller deficits slow progress.
Tips: Enter your accurate TDEE (use a TDEE calculator if unsure) and current body weight. For best results, track your intake and adjust based on weekly progress.
Q1: Why a 500 kcal deficit?
A: This creates steady, sustainable fat loss of about 1 pound per week while minimizing muscle loss.
Q2: Why 2.2g protein per kg?
A: Research shows this amount optimizes muscle protein synthesis and preservation during calorie restriction.
Q3: How should I distribute my macros?
A: After protein (2.2g/kg), fill remaining calories with carbs and fats based on preference (typically 20-30% fats, rest carbs).
Q4: Should I adjust as I lose weight?
A: Yes, recalculate weekly as your weight and TDEE change. Protein should stay at 2.2g/kg of current weight.
Q5: What if I'm not losing weight?
A: Double-check your TDEE and tracking accuracy. Metabolic adaptation may require periodic adjustments.
