1. What is Percentage Weight Loss?

Percentage weight loss is a standardized way to measure weight reduction that accounts for a person's starting weight. It provides a more meaningful measure than absolute weight loss, especially when comparing individuals of different sizes.

2. How Does the Calculator Work?

The calculator uses the percentage weight loss formula:

\[ \text{Percentage Weight Loss} = \left( \frac{\text{initial\_weight} - \text{current\_weight}}{\text{initial\_weight}} \right) \times 100 \]

Where:

\( initial\_weight \) — Starting weight in kilograms
\( current\_weight \) — Current weight in kilograms

Explanation: The formula calculates what percentage of the original body weight has been lost, providing a standardized measure of weight reduction.

3. Importance of Tracking Weight Loss

Details: Tracking percentage weight loss is important for monitoring health goals, assessing nutritional status, and identifying potential health concerns. Significant unintentional weight loss may indicate underlying health issues.

4. Using the Calculator

Tips: Enter your initial weight and current weight in kilograms. Both values must be positive numbers. The calculator will compute the percentage of weight lost relative to your starting weight.
