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 comparison than absolute weight loss numbers.

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 initial body weight you have lost.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps assess progress more accurately than just tracking pounds or kilograms lost, especially when comparing progress between individuals with different starting weights.

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)

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

Q4: Does this work for weight gain calculations too?

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