1. What is Calorie Deficit?

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

2. How Does the Calculator Work?

The calculator uses the Calorie Deficit formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( Calories \) — Daily Calorie Intake (kcal/day)

Explanation: TDEE represents the total number of calories your body burns in a day, including basal metabolic rate and physical activity. Subtracting your calorie intake from TDEE gives your daily calorie deficit.

3. Importance of Calorie Deficit

Details: Maintaining an appropriate calorie deficit is crucial for sustainable weight loss. A deficit of 500-1000 kcal/day typically results in a safe weight loss of 0.5-1 kg per week.

4. Using the Calculator

Tips: Enter your TDEE and daily calorie intake in kcal/day. Both values must be positive numbers. The calculator will compute your daily calorie deficit.

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 considered safe and sustainable for most people.

Q2: How do I calculate my TDEE?
A: TDEE can be estimated using formulas like Harris-Benedict or Mifflin-St Jeor, multiplied by an activity factor.

Q3: Can calorie deficit be too large?
A: Yes, excessively large deficits can lead to muscle loss, nutrient deficiencies, and metabolic adaptation.

Q4: Should I adjust my calorie deficit over time?
A: Yes, as you lose weight, your TDEE decreases, so you may need to recalculate and adjust your deficit periodically.

Q5: Is calorie deficit the only factor for weight loss?
A: While calorie deficit is primary, nutrient quality, macronutrient balance, and exercise type also influence body composition.
