1. What is a Calorie Deficit Calculator?

Definition: This calculator determines the calorie deficit by comparing your maintenance calories to your desired intake.

Purpose: It helps individuals plan their nutrition for weight loss by showing the difference between calories burned and calories consumed.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Deficit — Daily calorie shortfall (kcal)
• Maintenance — Calories needed to maintain current weight (kcal)
• Desired Intake — Target daily calorie consumption (kcal)

Explanation: The maintenance calories are subtracted from your desired intake to show your daily deficit.

3. Importance of Calorie Deficit Calculation

Details: Proper deficit calculation ensures safe and effective weight loss while maintaining energy levels and health.

4. Using the Calculator

Tips: Enter your maintenance calories and desired intake in kcal. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my maintenance calories?
A: Use a TDEE (Total Daily Energy Expenditure) calculator that considers your activity level, age, weight, and height.

Q2: What's a safe calorie deficit?
A: Typically 300-500 kcal/day for moderate weight loss, up to 1000 kcal/day for more aggressive plans under supervision.

Q3: Why is my deficit negative?
A: A negative deficit means you're consuming more than maintenance, which would lead to weight gain.

Q4: How accurate is this calculator?
A: It provides precise math, but actual results depend on accurate input values and individual metabolism.

Q5: Should I adjust my deficit over time?
A: Yes, as you lose weight, your maintenance calories decrease and you may need to recalculate.
