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, forcing your body to use stored fat for energy.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (calories your body burns daily)
• \( Calories \) — Actual calories consumed daily

Explanation: A positive deficit indicates weight loss potential, while a negative value suggests weight gain.

3. Importance of Calorie Deficit Calculation

Details: Calculating calorie deficit helps create effective weight loss plans, ensures sustainable fat loss, and prevents excessive calorie restriction that can harm metabolism.

4. Using the Calculator

Tips: Enter your TDEE and daily calorie intake in kcal/day. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a safe calorie deficit for weight loss?
A: A deficit of 500-1000 kcal/day is generally safe, leading to 1-2 pounds of weight loss per week.

Q2: How do I calculate my TDEE?
A: TDEE can be estimated using formulas like Mifflin-St Jeor or Harris-Benedict, considering your BMR and activity level.

Q3: Can too large a calorie deficit be harmful?
A: Yes, excessive deficits can cause muscle loss, nutrient deficiencies, and metabolic slowdown.

Q4: Should calorie deficit be consistent every day?
A: While consistency helps, weekly averages matter more. Some people use calorie cycling for flexibility.

Q5: How often should I recalculate my calorie needs?
A: Recalculate every 4-6 weeks or after significant weight loss (5-10% of body weight).
