The calculator uses the weight loss percentage formula:
Where:
Explanation: This calculation shows what percentage of your original body weight you've lost, which is particularly useful for comparing progress between people of different sizes.
Details: Tracking weight loss percentage rather than just pounds provides a more meaningful measure of progress, especially for those with significant amounts of weight to lose. It helps account for differences in starting weight when comparing progress between individuals.
Tips: Enter your starting weight in pounds and the amount of weight you've lost in pounds. For best results, weigh yourself at the same time of day under consistent conditions (e.g., morning after bathroom use).
Q1: Why use percentage instead of pounds lost?
A: Percentage accounts for different starting weights, making progress comparisons between people more fair and meaningful.
Q2: What is a good weight loss percentage?
A: A 5-10% weight loss can significantly improve health markers. Competitive weight loss programs often see 15-25% losses over several months.
Q3: How often should I calculate my weight loss percentage?
A: Weekly measurements can show trends while minimizing daily fluctuations. Monthly measurements show more significant progress.
Q4: Does this account for body composition changes?
A: No, this only measures total weight change. For body composition, additional measurements like body fat percentage are needed.
Q5: Can I use this if I've gained weight?
A: Yes, the calculation will show a negative percentage if your current weight is higher than your starting weight.
