1. What is the Weight Loss Formula?

The weight loss formula calculates estimated fat loss based on a sustained caloric deficit over time. It's based on 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)
• \( time\_days \) — Duration of deficit (days)
• \( 7700 \) — Energy content of 1 kg fat (kcal)

Explanation: The formula estimates how much body fat would be burned given a consistent daily energy deficit over a specified time period.

3. Importance of Caloric Deficit

Details: A caloric deficit is essential for weight loss, meaning you consume fewer calories than you expend. This formula helps quantify the relationship between deficit and weight loss.

4. Using the Calculator

Tips: Enter your average daily caloric deficit and the time period in days. The calculator will estimate your potential weight loss.

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 isn't my actual weight loss matching this calculation?
A: Actual weight loss can be affected by water retention, glycogen stores, muscle gain/loss, and metabolic adaptations.

Q3: Can I use this for weight gain calculations?
A: Yes, by using a caloric surplus instead of deficit, though muscle gain may not follow the same kcal/kg ratio as fat loss.

Q4: How accurate is this for short-term predictions?
A: Less accurate for short periods due to water weight fluctuations. More reliable for predictions over weeks or months.

Q5: Does exercise affect this calculation?
A: Exercise contributes to your total caloric deficit. The formula works the same whether deficit comes from diet, exercise, or both.
