Calorie Calculation Formula:
From: | To: |
This calculator helps determine the optimal calorie intake for simultaneous fat loss and muscle gain by calculating a 250 kcal deficit or surplus from your Total Daily Energy Expenditure (TDEE).
The calculator uses the formula:
Where:
Explanation: A 250 kcal adjustment from maintenance level provides an optimal balance for body recomposition - losing fat while building muscle.
Details: Precise calorie management is essential for effective body recomposition. Too large a deficit can lead to muscle loss, while too large a surplus can lead to excessive fat gain.
Tips: Enter your calculated TDEE value in kcal and select your goal (deficit for fat loss or surplus for muscle gain). Ensure your TDEE calculation is accurate for best results.
Q1: Why ±250 kcal specifically?
A: 250 kcal provides a moderate adjustment that supports muscle preservation during fat loss and lean muscle gain during surplus, minimizing fat accumulation.
Q2: How often should I recalculate my calorie needs?
A: Recalculate every 4-6 weeks or after significant weight changes (±5 kg) to account for metabolic adaptations.
Q3: Can I both lose fat and gain muscle simultaneously?
A: Yes, particularly for beginners, those returning to training, or with optimized nutrition and training protocols.
Q4: What if I'm not seeing results with ±250 kcal?
A: Individual responses vary. Adjust by ±100 kcal every 2 weeks based on progress measurements and energy levels.
Q5: How important is protein intake with this approach?
A: Crucial. Maintain 1.6-2.2g protein per kg body weight to support muscle protein synthesis during both deficit and surplus phases.
