1. What Is The Weight Loss Formula?

The weight loss formula calculates estimated fat loss based on caloric deficit over time. It uses the principle that 1 kg of body fat contains approximately 7,700 kcal of energy.

2. How Does The Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( deficit \) — Daily caloric deficit (kcal/day)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — Energy content of 1 kg body fat (kcal)

Explanation: The equation shows how sustained caloric deficit leads to fat loss over time.

3. Importance Of Caloric Deficit

Details: Caloric deficit is the foundation of weight loss. This calculator helps estimate realistic weight loss goals based on your planned deficit and timeframe.

4. Using The Calculator

Tips: Enter your daily caloric deficit (difference between calories consumed and burned) and the number of days you plan to maintain this deficit.

5. Frequently Asked Questions (FAQ)

Q1: Is 7,700 kcal/kg accurate for everyone?
A: This is an average value. Actual fat composition varies slightly between individuals.

Q2: Why isn't my weight loss matching the calculation?
A: Water retention, glycogen stores, and other factors can mask fat loss in short-term measurements.

Q3: What's a safe caloric deficit?
A: Generally 500-1000 kcal/day deficit is recommended for safe, sustainable weight loss.

Q4: Does this account for metabolic adaptation?
A: No, this is a simple calculation that doesn't account for metabolic changes during prolonged deficits.

Q5: Can I use this for weight gain calculations?
A: Yes, by using a caloric surplus instead of deficit, though muscle gain ratios differ from fat loss.
