1. What is Weight Loss Percentage?

The weight loss percentage measures how much weight you've lost relative to your starting weight. It provides a more accurate picture of progress than just tracking pounds or kilograms lost, especially for people with different starting weights.

2. How Does the Calculator Work?

The calculator uses the weight loss percentage formula:

\[ \text{Weight Loss Percentage} = \left( \frac{\text{Initial Weight} - \text{Current Weight}}{\text{Initial Weight}} \right) \times 100 \]

Where:

Explanation: The formula calculates what percentage of your original body weight you have lost. This gives a standardized measure that works for people of all sizes.

3. Importance of Tracking Weight Loss

Details: Tracking weight loss percentage helps monitor progress in weight management programs, assess effectiveness of diet/exercise regimens, and provides motivation by showing relative changes.

4. Using the Calculator

Tips: Enter your initial weight and current weight in kilograms. Both values must be valid (weight > 0) and current weight should not exceed 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 like blood pressure and cholesterol.

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 show 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).
