Explanation: The formula calculates what percentage of your original body weight you have lost. This gives a more accurate picture of progress than simply tracking pounds or kilograms lost.
Details: Tracking weight loss percentage helps individuals monitor their progress in a standardized way, set realistic goals, and stay motivated during weight loss journeys. It's particularly useful for healthcare professionals to assess patient progress.
Tips: Enter your starting 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 using the bathroom).
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 lead to health improvements.
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: Should I use the same scale for measurements?
A: Yes, using the same scale under similar conditions provides the most consistent results.
Q5: Can I use pounds instead of kilograms?
A: The calculator uses kg, but you can convert pounds to kg by dividing by 2.205. The percentage result would be the same regardless of units.
