Calorie Deficit Formula:
From: | To: |
A calorie deficit for cutting refers to consuming fewer calories than your body burns, specifically calculated as 20% below your Total Daily Energy Expenditure (TDEE). This creates an optimal environment for fat loss while preserving muscle mass during a cutting phase.
The calculator uses the calorie deficit formula:
Where:
Explanation: A 20% deficit is widely recommended as it creates substantial fat loss while minimizing muscle loss and metabolic adaptation.
Details: Calculating the right calorie deficit is crucial for effective fat loss. Too large a deficit can cause muscle loss and metabolic slowdown, while too small a deficit may not produce visible results.
Tips: Enter your calculated TDEE value in kcal/day. Make sure you have an accurate TDEE measurement before calculating your deficit for optimal results.
Q1: Why use a 20% deficit for cutting?
A: A 20% deficit balances effective fat loss with muscle preservation and sustainable energy levels.
Q2: How often should I recalculate my deficit?
A: Recalculate every 4-6 weeks or after significant weight loss (5-10% of body weight).
Q3: Should I adjust my deficit based on activity level?
A: Your TDEE already accounts for activity level, so the 20% deficit applies regardless of activity.
Q4: What if I'm not losing weight with a 20% deficit?
A: You may need to verify your TDEE calculation or consider metabolic adaptation factors.
Q5: Can I use a larger deficit for faster results?
A: Larger deficits may cause more muscle loss and are generally not recommended for extended periods.
