1. What is the Weight Loss Formula?

The weight loss formula estimates how much body weight you'll lose based on your daily calorie deficit and the time period. It's based on the principle that 1 kg of body weight is roughly equivalent to 7700 kcal.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

\[ \text{Weight Loss (kg)} = \frac{\text{deficit (kcal/day)} \times \text{days (days)}}{7700 \text{ (kcal/kg)}} \]

Where:

Explanation: The formula calculates total calorie deficit over time and converts it to kilograms of body weight.

3. Importance of Calorie Deficit

Details: Calorie deficit is the foundation of weight loss. This calculator helps set realistic expectations by quantifying the relationship between deficit and weight loss over time.

4. Using the Calculator

Tips: Enter your estimated daily calorie deficit (difference between calories consumed and calories burned) and the number of days you plan to maintain this deficit.

5. Frequently Asked Questions (FAQ)

Q1: Is the 7700 kcal/kg rule exact?
A: It's an approximation. Actual energy equivalent varies based on body composition and other factors.

Q2: Why isn't my weight loss matching the calculation?
A: Water retention, metabolic adaptation, and measurement inaccuracies can affect results.

Q3: Is the weight loss linear?
A: Typically no - weight loss often slows as you lose weight due to metabolic changes.

Q4: What's a safe calorie deficit?
A: Generally 500-1000 kcal/day for 0.5-1 kg/week loss. Extreme deficits can be unhealthy.

Q5: Does the type of calories matter?
A: For weight loss, total calories matter most, but nutrient quality affects health and satiety.
