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:

• \( initial \) — Your starting weight (kg or lbs)
• \( current \) — Your current weight (kg or lbs)

Explanation: The formula calculates the difference between your initial and current weight, divides by your initial weight to get a ratio, then multiplies by 100 to convert to percentage.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage is more meaningful than tracking absolute weight loss because it accounts for different starting weights. It provides a standardized metric to compare progress across individuals with different body sizes.

4. Using the Calculator

Tips: Enter your initial weight and current weight in the same units (either kg or lbs). Both values must be positive numbers. The calculator works for any unit of weight as long as both inputs use the same unit.

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.

Q2: What is considered a healthy weight loss percentage?
A: A 5-10% weight loss is often enough to see significant health benefits. More than 1-2% per week may be too rapid.

Q3: Can I use this for weight gain percentage?
A: Yes, the same formula works - the result will be negative if current weight is higher than initial weight.

Q4: Does the calculator work for any weight unit?
A: Yes, as long as both initial and current weights use the same unit (both kg or both lbs).

Q5: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended to track trends while minimizing daily fluctuations.
