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 what percentage of your original body weight you have lost, providing a standardized way to track progress regardless of your starting weight.
Details: Tracking weight loss percentage helps you monitor progress more accurately than just tracking pounds lost. It's particularly useful for comparing progress between individuals with different starting weights and for setting realistic goals in weight management programs.
Tips: Enter your starting weight and current weight using the same units (either kilograms or pounds). Both values must be positive numbers, with starting weight greater than current weight for weight loss.
Q1: Why use percentage instead of pounds/kilograms?
A: Percentage provides a relative measure that accounts for different starting weights, making it easier to compare progress between individuals.
Q2: What is considered significant weight loss?
A: A 5-10% weight loss is clinically significant and can lead to health improvements like reduced blood pressure and improved cholesterol levels.
Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended rather than daily, as daily weight fluctuations are normal and can be misleading.
Q4: Can I use this calculator for weight gain?
A: Yes, if your current weight is higher than your starting weight, the calculator will show a negative percentage, indicating weight gain.
Q5: Should I use the same scale for measurements?
A: For most accurate results, use the same scale at the same time of day (preferably morning) under similar conditions for all measurements.
