Calorie Deficit Formula:
| From: | To: |
The Fat Loss Calorie Calculator estimates the daily calorie intake needed to create a calorie deficit for fat loss based on your Total Daily Energy Expenditure (TDEE). A 500-calorie deficit per day typically results in about 1 pound of fat loss per week.
The calculator uses the Calorie Deficit formula:
Where:
Explanation: The equation calculates the optimal calorie intake for fat loss by subtracting 500 calories from your maintenance level (TDEE).
Details: Calculating the appropriate calorie deficit is crucial for sustainable fat loss while maintaining muscle mass and energy levels. A 500-calorie deficit is generally considered safe and effective for most individuals.
Tips: Enter your TDEE in kcal. The value must be valid (TDEE > 0). For accurate results, use a reliable TDEE calculator or have your TDEE measured professionally.
Q1: Why subtract 500 calories from TDEE?
A: A 500-calorie deficit creates approximately 3500 calories deficit per week, which equals about 1 pound of fat loss, making it a sustainable and healthy rate.
Q2: What if my TDEE changes during my weight loss journey?
A: As you lose weight, your TDEE will decrease. It's important to recalculate your calorie needs every few weeks to maintain an appropriate deficit.
Q3: Is a 500-calorie deficit appropriate for everyone?
A: While generally safe, individual needs may vary. Very active individuals or those with higher starting weights may tolerate larger deficits, while others may need smaller deficits.
Q4: Should I adjust my macronutrients while in a calorie deficit?
A: Yes, maintaining adequate protein intake is crucial to preserve muscle mass while losing fat. Aim for 1.6-2.2g of protein per kg of body weight.
Q5: How long should I maintain a calorie deficit?
A: This depends on your fat loss goals. It's generally recommended to take maintenance breaks every 8-12 weeks to prevent metabolic adaptation and maintain psychological well-being.
