The calculator uses the weight loss percentage formula:

\[ \text{Weight Loss Percentage} = \frac{\text{Initial Weight} - \text{Current Weight}}{\text{Initial Weight}} \times 100 \]

Where:

Explanation: The formula calculates what percentage of your original body weight you have lost, which is more informative than just tracking pounds or kilograms lost.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps monitor progress in weight management programs, assess the effectiveness of diet and exercise regimens, and provides motivation by showing relative progress.

4. Using the Calculator
