1. What is Weight Loss Percentage?

Weight loss percentage is a standardized way to measure weight reduction regardless of starting weight. It provides a more meaningful measure than absolute weight loss, especially when comparing progress between individuals with different starting weights.

2. How Does the Calculator Work?

The calculator uses the weight loss percentage formula:

Where:

• Initial Weight — Starting weight before weight loss (kg)
• Current Weight — Present weight after weight loss (kg)

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 monitor progress in weight management programs, assess the effectiveness of diet/exercise regimens, and provides motivation by quantifying achievements.

4. Using the Calculator

Tips: Enter your initial weight and current weight in kilograms. Both values must be positive numbers, with current weight less than or equal to initial weight.

5. Frequently Asked Questions (FAQ)

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

Q2: What is considered significant weight loss?
A: A 5-10% reduction in body weight is clinically significant and can improve health markers.

Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended to track trends while minimizing daily fluctuations.

Q4: Does this work for weight gain too?
A: Yes, the same formula shows percentage change - negative values indicate weight gain.

Q5: Should I use the same scale for measurements?
A: For consistency, use the same scale at the same time of day (preferably morning before eating).
