1. What is Weight Loss Percentage?

Weight loss percentage is a standardized way to measure weight reduction that accounts for differences in starting weight. It provides a more meaningful comparison than absolute weight loss numbers.

2. How Does the Calculator Work?

The calculator uses the weight loss percentage formula:

Where:

• Initial Weight — Starting body weight in kilograms
• Current Weight — Current body 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 monitor progress in weight management programs, assess effectiveness of interventions, and set realistic goals.

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 comparisons more meaningful between individuals.

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 can calculate percentage weight gain if current weight exceeds initial weight.

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