How to calculate weight loss percentage
Calculating your weight loss as a percentage gives you a more accurate picture of your progress than just looking at the number of pounds or kilograms lost. It scales your progress relative to your starting weight. To find this percentage, subtract your current weight from your starting weight to get the total weight lost. Then, divide that number by your starting weight and multiply by 100. For example, losing 10 lbs from 200 lbs is a 5% loss, whereas losing 10 lbs from 150 lbs is a 6.7% loss.
Understanding body fat percentage ranges
Body fat percentage is the total mass of fat divided by total body mass. Unlike BMI, it distinguishes between muscle and fat. For men, essential fat is 2–5%, athletes range from 6–13%, and fitness ranges from 14–17%. For women, essential fat is 10–13%, athletes range from 14–20%, and fitness ranges from 21–24%. Tracking body fat helps ensure that weight loss is coming from fat stores rather than lean muscle mass.
