Weight Loss Percentage Formula:
| From: | To: |
Weight loss percentage is a measurement that shows how much weight you've lost relative to your starting weight. It provides a more accurate picture of progress than simply tracking pounds or kilograms lost, especially for people with different starting weights.
The calculator uses the weight loss percentage formula:
Where:
Explanation: This formula calculates the percentage of weight lost from your original weight, giving you a standardized measure of your progress.
Details: Tracking weight loss percentage helps you monitor your progress objectively, set realistic goals, and stay motivated throughout your weight loss journey. It's particularly useful for comparing progress among individuals with different starting weights.
Tips: Enter your starting weight and current weight in kilograms. Both values must be valid (weight > 0, current weight should not exceed starting weight).
Q1: Why use percentage instead of absolute weight loss?
A: Percentage provides a relative measure that accounts for different starting weights, making progress comparisons more meaningful across individuals.
Q2: What is considered a healthy weight loss percentage?
A: A 5-10% weight loss is generally considered clinically significant and can lead to health improvements. Weekly loss of 0.5-1% is typically recommended.
Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended rather than daily, as daily fluctuations can be misleading and discouraging.
Q4: Does this work for weight gain calculations?
A: The same formula can be used for weight gain by reversing the values, though the interpretation would be different.
Q5: Should I use the same scale for consistent measurements?
A: Yes, using the same scale at the same time of day (preferably morning) provides the most consistent and accurate measurements.
