1. What is the Fat Loss Equation?

The fat loss equation estimates how much body fat you can lose based on your daily caloric deficit over a period of time. It assumes that 1 kg of body fat contains approximately 7700 kcal of energy.

2. How Does the Calculator Work?

The calculator uses the fat 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 calculates fat loss based on the principle that consuming fewer calories than you burn leads to fat loss, with 7700 kcal deficit equating to approximately 1 kg of fat loss.

3. Importance of Caloric Deficit

Details: Maintaining a consistent caloric deficit is the fundamental principle behind fat loss. This calculator helps estimate results based on your planned deficit.

4. Using the Calculator

Tips: Enter your daily caloric deficit (difference between calories consumed and calories burned) and the duration in days. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is the 7700 kcal/kg value accurate for everyone?
A: While 7700 kcal/kg is a widely accepted estimate, individual variations in body composition may cause slight differences.

Q2: Why doesn't my actual weight loss match the calculation?
A: Initial weight loss often includes water weight, and the body may adapt metabolically over time. Also, the calculation assumes 100% of weight loss comes from fat.

Q3: What's a safe daily caloric deficit?
A: Generally, 500-1000 kcal/day deficit is recommended for sustainable fat loss of 0.5-1 kg per week.

Q4: Does exercise affect this calculation?
A: Exercise increases your total daily energy expenditure, which can contribute to your caloric deficit.

Q5: Should I use this for long-term weight loss planning?
A: While useful for estimation, consult a nutritionist for personalized long-term plans as metabolic adaptations occur over time.
