1. What is Percentage of Body Weight Loss?

Percentage of body weight loss is a standardized way to measure weight reduction that accounts for differences in starting weight. It provides a more meaningful measure than absolute weight loss when comparing between individuals with different initial weights.

2. How Does the Calculator Work?

The calculator uses the weight loss percentage formula:

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 loss progress.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage is important for monitoring progress in weight management programs, assessing nutritional status in clinical settings, and evaluating the effectiveness of dietary interventions.

4. Using the Calculator

Tips: Enter both weights in kilograms (kg). For accurate results, weigh yourself at the same time of day (preferably morning) under similar conditions (fasting state, after bathroom use).
