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:

\[ \text{Weight Loss Percentage} = \left( \frac{\text{lbs lost}}{\text{starting weight}} \right) \times 100 \]

Where:

Explanation: The formula calculates what percentage of your original body weight you've lost, which is more meaningful than just tracking pounds.

3. Importance of Tracking Weight Loss Percentage

Details: Tracking weight loss percentage helps compare progress across different body sizes, sets realistic goals, and provides motivation by showing relative progress.

4. Using the Calculator

Tips: Enter pounds lost and starting weight in pounds. Both values must be positive numbers, and pounds lost cannot exceed starting weight.

5. Frequently Asked Questions (FAQ)

Q1: Why use percentage instead of pounds?
A: Percentage accounts for different starting weights, making progress comparable between people of different sizes.

Q2: What is a good weight loss percentage?
A: A 5-10% weight loss is clinically significant for health benefits. More than 1-2% per week may be unsustainable.

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 by using the weight gained instead of lost.

Q5: Should I use my current weight or starting weight?
A: Always use your original starting weight as the denominator for consistent percentage calculations.
