1. What is Weight Loss Percentage?

Weight loss percentage is a standardized way to measure weight loss that accounts for different starting weights. It provides a more meaningful comparison than absolute weight loss in kilograms.

2. How Does the Calculator Work?

The calculator uses the weight loss percentage formula:

Where:

• \( Loss \) — Weight lost in kilograms
• \( Start \) — Starting weight in kilograms

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

3. Importance of Weight Loss Tracking

Details: Tracking weight loss percentage helps monitor progress in weight management programs and provides motivation by showing relative progress regardless of starting weight.

4. Using the Calculator

Tips: Enter your starting weight and weight lost in kilograms. Both values must be positive numbers, and weight loss cannot exceed starting weight.

5. Frequently Asked Questions (FAQ)

Q1: Why use percentage instead of kilograms?
A: Percentage accounts for different starting weights, making progress comparable between individuals of different sizes.

Q2: What is a healthy weight loss percentage?
A: A 5-10% weight loss is often enough to see significant health benefits, while more than 10% is considered substantial.

Q3: How often should I calculate my weight loss percentage?
A: Weekly or bi-weekly measurements are recommended to track trends without focusing too much on daily fluctuations.

Q4: Does this work for weight gain too?
A: Yes, the same formula can calculate percentage of weight gained relative to starting weight.

Q5: Should I use my current weight or starting weight?
A: For percentage calculations, always use your original starting weight as the reference point.
