1. What is Weight Loss Percentage?

Weight loss percentage is a standardized way to measure weight loss that accounts for differences in starting weight. It provides a more meaningful comparison than absolute weight loss numbers, especially for people with different body sizes.

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 your original body weight you have lost, which is more meaningful than just tracking pounds or kilograms lost.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps monitor progress in weight management programs, assess the effectiveness of diet and exercise regimens, and provides motivation by showing relative progress.

4. Using the Calculator

Tips: Enter your starting weight and current weight in kilograms. For accurate results, weigh yourself at the same time of day (preferably morning) under similar conditions.

5. Frequently Asked Questions (FAQ)

Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended to see trends without daily fluctuations.

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

Q5: Should I use kg or pounds?
A: The calculator uses kg, but you can convert from pounds (1 lb = 0.453592 kg).
