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 of progress than absolute weight loss numbers.

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.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps assess the effectiveness of diet and exercise programs, provides motivation, and allows for better comparison between individuals with different starting weights.

4. Using the Calculator

Tips: Enter your starting 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 instead of pounds/kilos lost?
A: Percentage accounts for different starting weights, making progress comparable between people of different sizes.

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?

Q5: How often should I calculate my weight loss percentage?
A: Weekly measurements are most useful as daily weight fluctuates due to water retention and other factors.
