1. What is the Weight Loss Formula?

The weight loss formula calculates expected weight reduction based on daily caloric deficit over time. 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 weight loss formula:

Where:

• \( deficit \) — Daily caloric deficit (kcal/day)
• \( days \) — Time period in days
• \( 7700 \) — kcal equivalent of 1 kg body weight

Explanation: The formula estimates weight loss by dividing total caloric deficit by the energy equivalent of body fat.

3. Importance of Caloric Deficit

Details: Caloric deficit is the cornerstone of weight loss. This calculation helps set realistic expectations and plan dietary/exercise interventions.

4. Using the Calculator

Tips: Enter your daily caloric deficit (difference between calories consumed and expended) and the time period you want to evaluate. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal/kg accurate for everyone?
A: This is an average value. The exact energy equivalent may vary slightly based on body composition.

Q2: Why isn't my actual weight loss matching the calculation?
A: Many factors affect weight loss including water retention, metabolic adaptation, and measurement inaccuracies.

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

Q4: Does the formula account for metabolic changes?
A: No, this is a simple calculation that doesn't account for metabolic adaptation that occurs with prolonged dieting.

Q5: Can I use this for weight gain calculations?
A: Yes, by using caloric surplus instead of deficit, though muscle gain may not follow the same exact ratio.
