Weight Loss Formula:
| From: | To: |
Weight loss percentage is a standardized way to measure weight reduction regardless of starting weight. It shows how much weight you've lost relative to your initial weight, making it easier to compare progress between individuals with different starting weights.
The calculator uses the weight loss percentage formula:
Where:
Explanation: The formula calculates what percentage of your original body weight you've lost, which is a more meaningful metric than absolute weight loss for tracking progress.
Details: Tracking weight loss percentage helps monitor progress in weight management programs, provides motivation, and helps assess the effectiveness of diet and exercise regimens. It's particularly useful for those with significant weight to lose.
Tips: Enter your initial weight and current weight in kilograms. For best results, weigh yourself at the same time of day (preferably morning) under consistent conditions (before eating, after bathroom use).
Q1: Why use percentage instead of pounds/kilos lost?
A: Percentage loss accounts for different starting weights, making progress comparable between individuals of different sizes.
Q2: What is a healthy weight loss percentage?
A: A 5-10% weight loss is clinically significant for health benefits. 1-2% per month is generally considered safe and sustainable.
Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended, as daily weight can fluctuate due to water retention and other factors.
Q4: Does this work for weight gain too?
A: Yes, the formula will show negative percentages if current weight exceeds initial weight.
Q5: Should I use the same scale for measurements?
A: Yes, using the same scale under similar conditions provides the most consistent measurements.
