Calorie Deficit Formula:
| From: | To: |
Intermittent fasting combined with calorie deficit is a weight management strategy that involves restricting eating to specific time windows while consuming fewer calories than your body burns. This approach can help promote fat loss while maintaining muscle mass.
The calculator uses the Calorie Deficit formula:
Where:
Explanation: The equation calculates the difference between the calories your body burns and the calories you consume, indicating your daily energy deficit.
Details: Calculating calorie deficit is essential for effective weight management. A controlled calorie deficit combined with intermittent fasting can help achieve sustainable weight loss while maintaining metabolic health.
Tips: Enter your TDEE (Total Daily Energy Expenditure) and your actual daily calorie intake. Both values must be positive numbers measured in kcal/day.
Q1: What is a safe calorie deficit for weight loss?
A: A deficit of 500-1000 kcal/day is generally considered safe and sustainable, leading to 0.5-1 kg weight loss per week.
Q2: How does intermittent fasting enhance calorie deficit?
A: Intermittent fasting helps create a natural calorie deficit by limiting eating windows, reducing overall calorie intake while maintaining metabolic rate.
Q3: What are the different intermittent fasting methods?
A: Common methods include 16:8 (16 hours fasting, 8 hours eating), 5:2 (5 normal days, 2 restricted days), and alternate-day fasting.
Q4: Can I combine intermittent fasting with other diets?
A: Yes, intermittent fasting can be combined with various dietary approaches like keto, Mediterranean, or balanced nutrition for enhanced results.
Q5: How often should I recalculate my calorie needs?
A: Recalculate every 4-6 weeks or after significant weight changes (5+ kg) to adjust for metabolic adaptations.
