1. What is the Weight Loss Formula?

The weight loss formula calculates expected fat loss based on your daily 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)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — Energy content of 1 kg fat (kcal)

Explanation: The formula estimates fat loss by dividing total accumulated deficit by the energy density of body fat.

3. Importance of Caloric Deficit

Details: Creating a consistent caloric deficit is the fundamental requirement for fat loss. This calculator helps predict results based on your planned deficit.

4. Using the Calculator

Tips: Enter your planned daily caloric deficit and the duration in days. For best results, use accurate estimates of your maintenance calories.

5. Frequently Asked Questions (FAQ)

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

Q2: Why isn't my weight loss matching the prediction?
A: Water weight fluctuations, changes in lean mass, and metabolic adaptations can affect actual results.

Q3: What's a safe daily caloric deficit?
A: Generally 300-1000 kcal/day is recommended, depending on your starting weight and activity level.

Q4: Does exercise affect this calculation?
A: Exercise increases your total deficit. Include exercise calories in your deficit calculation for more accurate predictions.

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