The calculator uses the weight loss percentage formula:
Where:
Explanation: This formula calculates what percentage of your current body weight you've lost during the measured period, providing a standardized way to track progress regardless of starting weight.
Details: Tracking weight loss percentage rather than just absolute weight lost helps account for different starting weights among individuals, making progress comparisons more meaningful and helping to set realistic goals.
Tips: Enter your weekly weight loss in kilograms and your current weight in kilograms. For accurate results, weigh yourself at the same time of day under similar conditions (e.g., first thing in the morning after using the bathroom).
Q1: Why use percentage instead of absolute weight loss?
A: Percentage weight loss accounts for different starting weights, making it a fairer comparison between individuals and helping to set appropriate goals based on body size.
Q2: What is a healthy weekly weight loss percentage?
A: Most experts recommend 0.5-1% of body weight per week as a safe and sustainable rate of weight loss.
Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements are typically most useful as daily fluctuations can be misleading due to water weight 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 and reliable measurements.
Q5: Is this calculation appropriate for everyone?
A: While useful for most adults, those with certain medical conditions or who are pregnant should consult healthcare providers for personalized guidance.
