1. What is Luke's Fasting Formula?

Luke's fasting formula estimates weight loss based on the number of fasting days and daily calorie deficit. It's based on the principle that a 7700 kcal deficit equals approximately 1 kg of weight loss.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( fasting\_days \) — Number of fasting days
• \( calorie\_deficit \) — Daily calorie deficit (kcal/day)
• \( 7700 \) — Caloric equivalent of 1 kg body weight

Explanation: The formula calculates total calorie deficit over the fasting period and converts it to kilograms of weight loss.

3. Importance of Calorie Deficit

Details: Consistent calorie deficit is key for weight loss. Fasting helps create this deficit by restricting eating windows and reducing overall calorie intake.

4. Using the Calculator

Tips: Enter number of fasting days and estimated daily calorie deficit. For accurate results, track your actual calorie intake and expenditure.

5. Frequently Asked Questions (FAQ)

Q1: Is the 7700 kcal/kg rule accurate for everyone?
A: While generally accepted, individual results may vary based on metabolism, body composition, and other factors.

Q2: What's a safe calorie deficit?
A: Typically 300-500 kcal/day for moderate weight loss, up to 1000 kcal/day for more aggressive loss under supervision.

Q3: Does fasting preserve muscle better than regular dieting?
A: Some studies suggest fasting may help preserve lean mass during weight loss, but results vary.

Q4: How should I combine fasting with exercise?
A: Time workouts during eating windows or consume protein around workouts to support muscle retention.

Q5: Are there limitations to this formula?
A: It doesn't account for metabolic adaptation, water weight fluctuations, or changes in activity level.
