1. What Is the Weight Loss Formula?

The weight loss formula calculates expected fat loss based on caloric deficit over time. It's based on the scientific understanding 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)
• \( days \) — Time period (days)
• \( 7700 \) — Energy equivalent of 1 kg body fat (kcal/kg)

Explanation: The equation converts your total caloric deficit into kilograms of fat loss based on the energy density of body fat.

3. Importance of Accurate Calculation

Details: Understanding the relationship between caloric deficit and weight loss helps set realistic expectations and create effective diet plans.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is the 7,700 kcal/kg value accurate for everyone?
A: While 7,700 kcal/kg is a good average, individual variation exists based on body composition and metabolic factors.

Q2: Why is this considered most accurate for women?
A: Women's fat tissue typically has slightly higher water content, making the 7,700 kcal/kg estimate more accurate than the 7,716 kcal/kg sometimes used for men.

Q3: Does this account for metabolic adaptation?
A: No, this is a theoretical calculation. In reality, metabolism may slow down with prolonged caloric restriction.

Q4: What about weight loss from water or muscle?
A: This calculates fat loss specifically. Actual scale weight may change more due to water fluctuations.

Q5: How should I determine my caloric deficit?
A: Calculate your TDEE (Total Daily Energy Expenditure) and subtract your desired deficit (typically 300-500 kcal/day for sustainable loss).
