1. What is the Weight Loss Calculation?

The weight loss calculation estimates how much body weight you can lose based on your daily calorie deficit (TDEE minus intake) over a period of time. It's based on the principle that 7700 kcal deficit equals approximately 1 kg of weight loss.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( Intake \) — Actual calorie intake (kcal/day)
• \( Days \) — Duration of calorie deficit (days)
• \( 7700 \) — Approximate kcal deficit needed to lose 1 kg

Explanation: The formula calculates the total calorie deficit over time and converts it to kilograms of weight loss based on the 7700 kcal/kg conversion factor.

3. Importance of Calorie Deficit

Details: Understanding your potential weight loss helps set realistic goals and expectations. It demonstrates how small daily deficits accumulate over time to significant results.

4. Using the Calculator

Tips: Enter your TDEE (use a TDEE calculator if unknown), your planned daily calorie intake, and the number of days you plan to maintain this deficit. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal/kg accurate for everyone?
A: It's an average estimate. Actual weight loss can vary based on body composition, metabolic adaptation, and other factors.

Q2: Why might actual weight loss differ?
A: Water retention, glycogen stores, metabolic changes, and measurement errors can all affect actual scale weight.

Q3: Is it safe to create large deficits?
A: Generally, deficits of 500-1000 kcal/day are recommended for safe, sustainable weight loss (0.5-1 kg/week).

Q4: Does the calculation account for metabolic adaptation?
A: No, as your weight changes, your TDEE will decrease, which isn't accounted for in this simple calculation.

Q5: What if my intake is higher than my TDEE?
A: The calculator will show negative weight loss (weight gain) proportional to the calorie surplus.
