1. What is Weight Loss Percentage?

Weight loss percentage calculates how much weight you've lost relative to your starting weight. This provides a more meaningful measure 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:

Where:

• \( loss\_week \) — Weight lost during the week (kg)
• \( initial \) — Initial weight before the week (kg)

Explanation: The formula calculates what percentage of your original body weight you've lost during the week.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps monitor progress more accurately than absolute weight loss, especially for people with different starting weights. It provides a standardized way to compare progress.

4. Using the Calculator

Tips: Enter your weight loss during the week and your initial weight before that week. Both values must be positive numbers (initial weight must be greater than 0).
