1. What is a Fat Loss Calculator by Deficit?

Definition: This calculator estimates fat loss in kilograms based on your total caloric deficit.

Purpose: It helps individuals understand how their caloric deficit translates to actual fat loss over time.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• 1 kg of body fat ≈ 7700 kcal
• Deficit — Total calories consumed minus calories expended

Explanation: The formula is based on the scientific estimate that 1 kg of body fat contains approximately 7700 kilocalories of energy.

3. Importance of Fat Loss Calculation

Details: Understanding this relationship helps set realistic weight loss goals and expectations based on dietary and exercise plans.

4. Using the Calculator

Tips: Enter your total caloric deficit in kilocalories (kcal). The value must be positive.

5. Frequently Asked Questions (FAQ)

A: No, this calculates pure fat loss based on energy balance. Actual weight changes may vary due to other factors.

Q3: How can I track my caloric deficit?
A: Use food tracking apps for intake and activity trackers for expenditure, or consult a nutritionist.

Q4: Is fat loss linear with this calculation?
A: While the energy math is accurate, biological factors can make weight loss non-linear over time.

Q5: What's a safe rate of fat loss?
A: Generally 0.5-1 kg per week is considered safe and sustainable for most people.
