1. What is the Weight Loss Calculation?

The weight loss calculation estimates how much weight you can lose based on your daily calorie deficit over a period of time. It's based on the principle that 1kg of body fat contains approximately 7,700 kcal.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( deficit \) — Daily calorie deficit (kcal/day)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — Calories in 1kg of body fat (kcal/kg)

Explanation: The equation calculates how much body fat you'll burn based on your sustained calorie deficit over time.

3. Importance of Calorie Deficit

Details: Creating a calorie deficit is the fundamental requirement for weight loss. This calculator helps estimate realistic weight loss goals based on your planned deficit.

4. Using the Calculator

Tips: Enter your daily calorie deficit (difference between calories consumed and burned) and the number of days you plan to maintain this deficit. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is 7,700 kcal really equal to 1kg of fat?
A: While this is a widely accepted estimate, individual results may vary slightly due to body composition and metabolic factors.

Q2: What's a safe daily calorie deficit?
A: Generally 500-1000 kcal/day is recommended for safe, sustainable weight loss of 0.5-1kg per week.

Q3: Why isn't my actual weight loss matching the calculation?
A: Water retention, muscle gain, metabolic adaptation, and inaccurate calorie tracking can all affect results.

Q4: Can I use this for weight gain calculations?
A: Yes, the same principle applies in reverse - surplus calories divided by 7,700 estimates potential weight gain.

Q5: Is this calculation different for men and women?
A: The basic calculation is the same, but men and women may have different baseline calorie needs affecting how they achieve a deficit.
