1. What is Weight Loss Percentage?

Weight loss percentage is a measurement that shows how much weight you've lost relative to your starting weight. It provides a more accurate picture of progress than just tracking pounds or kilograms lost, especially for people with different starting weights.

2. How Does the Calculator Work?

The calculator uses the weight loss percentage formula:

\[ \text{Weight Loss \%} = \frac{\text{Initial Weight} - \text{Final Weight}}{\text{Initial Weight}} \times 100 \]

Where:

Initial Weight — Your starting weight in kilograms
Final Weight — Your current weight in kilograms

Explanation: This formula calculates the proportion of weight lost relative to your original weight, expressed as a percentage.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps monitor progress in weight management programs, provides motivation, and allows for better comparison between individuals with different starting weights. It's particularly useful for healthcare professionals and fitness trainers to assess client progress.

4. Using the Calculator

Tips: Enter both initial and final weights in kilograms. Ensure final weight is less than or equal to initial weight for meaningful results. Use consistent units for accurate calculations.
