Weight Loss Percentage Calculator
Love it or hate it, NBC's The Biggest Loser sure does get people interested in weight loss. A lot of you want to know how to calculate the percentage of weight loss like they do on the show. So, I've created this handy weight loss calculator for you to check your percentage of weight loss.
Weight Loss Percentage Formula
The formula to calculate your weight loss percentage is: lbs lost divided by starting weight. Then, multiply the result by 100.
Example:
(5lbs / 150lbs) * 100 = -3.33%
So, if your starting weight is 150lbs and you lost 5lbs, you’ve lost 3.33% of your body weight.
Note: Please keep in mind, this calculates total weight loss including muscle. A better indicator of how you're doing would be to calculate how much body fat you're losing. It's the fat you want to lose, not the muscle!
Use the FitWatch Body Fat Percentage Calculator to estimate how much body fat you're losing.
