1. What is Body Weight Percentage Lost?

Body Weight Percentage Lost is a measure of how much weight you've lost relative to your starting weight. It provides a more meaningful measure of progress than absolute weight loss, especially for people with different starting weights.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Initial Weight — Your starting weight in kilograms
• Current Weight — Your current weight in kilograms

Explanation: The formula calculates what percentage of your original body weight you have lost.

3. Importance of Tracking Weight Loss

Details: Tracking percentage lost helps assess the effectiveness of weight loss programs, provides motivation, and helps set realistic goals. Medical professionals often use this metric to evaluate weight loss interventions.

4. Using the Calculator

Tips: Enter your initial weight and current weight in kilograms. Both values must be positive numbers. For accurate tracking, weigh yourself at the same time of day under similar conditions.

5. Frequently Asked Questions (FAQ)

Q1: Why use percentage lost instead of pounds/kilos lost?
A: Percentage lost provides a standardized measure that accounts for different starting weights, making it easier to compare progress between individuals.

Q2: What is considered significant weight loss?
A: A 5-10% weight loss is clinically significant and can lead to health improvements. Greater than 10% is considered substantial weight loss.

Q3: How often should I calculate my percentage lost?
A: Weekly or bi-weekly measurements are recommended. Daily fluctuations can be misleading due to normal weight variations.

Q4: Does this work for weight gain too?
A: Yes, the calculation will show a negative percentage if current weight exceeds initial weight, indicating percentage gained.

Q5: Should I use the same scale for measurements?
A: Yes, using the same scale under similar conditions (time of day, clothing, etc.) provides the most consistent results.
