1. What is Calorie Deficit?

Calorie deficit occurs when you consume fewer calories than your body expends. It's the fundamental principle behind weight loss, as your body taps into stored energy (fat) to make up for the energy shortfall.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{TDEE} \) — Total Daily Energy Expenditure (kcal/day)
• \( \text{Calories} \) — Actual calorie intake (kcal/day)

Explanation: This calculation provides the most accurate measurement of calorie deficit when using your measured TDEE value rather than estimated calculations.

3. Importance of Calorie Deficit Calculation

Details: Accurate calorie deficit tracking is crucial for effective weight management, ensuring sustainable weight loss while maintaining muscle mass and overall health.

4. Using the Calculator

Tips: Enter your measured TDEE value and daily calorie intake. Both values must be positive numbers. For best results, use accurately measured TDEE from metabolic testing.

5. Frequently Asked Questions (FAQ)

Q1: What is TDEE and how is it measured?
A: TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day. It can be accurately measured through metabolic testing or estimated using various formulas.

Q2: How much calorie deficit is safe for weight loss?
A: A deficit of 500-1000 kcal/day is generally safe, resulting in 1-2 pounds of weight loss per week. Extreme deficits can be counterproductive.

Q3: Why use measured TDEE instead of estimated?
A: Measured TDEE provides personalized accuracy, accounting for individual metabolic variations that estimation formulas may miss.

Q4: How often should I recalculate my calorie deficit?
A: Reassess every 4-6 weeks as weight loss affects metabolism, or whenever your activity level changes significantly.

Q5: Can I maintain muscle mass while in calorie deficit?
A: Yes, with adequate protein intake, strength training, and a moderate deficit, you can preserve muscle mass while losing fat.
