1. What is Weight Loss Percentage?

Weight loss percentage measures how much weight you've lost relative to your starting weight. It provides a more accurate picture of progress than just tracking pounds or kilograms lost, especially for people with different starting weights.

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, which helps standardize comparisons between individuals of different sizes.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps monitor progress more accurately than absolute weight changes, especially for those with significant amounts of weight to lose. It's a better indicator of health improvements and can be more motivating.

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 absolute weight?
A: Percentage accounts for different starting weights, making progress comparisons more meaningful between individuals.

A: 5-10% weight loss is clinically significant for health improvements. 1-2% per month is generally safe and sustainable.

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 for consistency.

Q4: Does this account for muscle vs fat loss?
