1. What is the Calorie Deficit Formula?

The calorie deficit formula calculates the daily calorie reduction needed to achieve a specific weight loss goal over a given time period. It's based on the principle that 1 kg of body weight is approximately equivalent to 7700 kcal.

2. How Does the Calculator Work?

The calculator uses the calorie deficit equation:

Where:

• \( weight\_loss\_kg \) — Desired weight loss in kilograms
• \( days \) — Time period for weight loss in days
• \( 7700 \) — kcal per kg of body weight

Explanation: The equation calculates the daily calorie deficit needed to lose the specified amount of weight in the given time frame.

3. Importance of Calorie Deficit Calculation

Details: Knowing your required calorie deficit helps create an effective weight loss plan by combining diet and exercise to achieve sustainable results.

4. Using the Calculator

Tips: Enter your weight loss goal in kilograms and the number of days you want to achieve it in. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why 7700 kcal per kg?
A: This is the approximate energy contained in 1 kg of body fat, though individual results may vary slightly.

Q2: Is this deficit safe for everyone?
A: Generally, deficits of 500-1000 kcal/day are recommended. Consult a healthcare provider for personalized advice.

Q3: Can I lose weight faster with a larger deficit?
A: While possible, very large deficits may lead to muscle loss, nutritional deficiencies, and metabolic slowdown.

Q4: Does this account for metabolic changes during weight loss?
A: No, as you lose weight your TDEE decreases, so you may need to adjust your deficit over time.

Q5: Should I combine this with exercise?
A: Yes, combining diet and exercise is most effective for sustainable weight loss and health benefits.
