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 shows how much weight you've lost relative to your initial weight, expressed as a percentage.

2. How Does the Calculator Work?

The calculator uses the weight loss percentage 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 weight loss percentage is more meaningful than tracking absolute weight loss because it accounts for differences in body size. A 5% weight loss is considered clinically significant for health benefits.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why use percentage instead of kilograms lost?
A: Percentage loss 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 can significantly improve health markers. More than 1-2% per week may be too rapid.

Q3: When should I measure my weight?
A: First thing in the morning after using the bathroom, before eating or drinking, and with minimal clothing.

Q4: Does this account for muscle vs fat loss?
A: No, this only measures total weight change. Body composition measurements provide more detail.

Q5: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended as daily weight can fluctuate due to water retention.
