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 measure than absolute weight loss, especially when comparing progress between individuals 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 informative than just knowing how many kilograms you've lost.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps monitor progress in weight management programs, provides motivation, and helps set realistic goals. A 5-10% weight loss can significantly improve health markers.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's considered a healthy weight loss percentage?
A: A 5-10% weight loss over 6 months is generally recommended for health benefits. More rapid weight loss may not be sustainable.

Q2: Why use percentage instead of kilograms?
A: Percentage accounts for different starting weights - losing 5kg means more to a 60kg person than a 120kg person.

Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended, as daily fluctuations can be misleading due to water retention.

Q4: Does this work for weight gain too?
A: Yes, the same formula can show percentage weight gain if current weight is higher than initial weight.

Q5: What if my weight loss stalls?
A: Plateaus are normal. Focus on non-scale victories like improved energy, clothing fit, or measurements.
