Body fat percentage - knowledge needed to lose weight


Jan 13, 2019
What is body fat percentage?

Your body fat percentage is the percentage of your body weight that’s fat.

For example, if you weigh 150 pounds and have 15 pounds of fat, your body fat percentage is 10% (15 / 150).

This means that your body fat percentage is a moving target, changing when you gain or lose fat, of course, but it also when you gain or lose muscle.

For example, if you used proper diet and weightlifting to increase your weight from 150 to 170 pounds with just 5 pounds of additional fat gain, your new body fat percentage would be about 12% (20 / 170).

If you then stopped lifting for a year and lost, let’s say, 10 pounds of muscle but no fat, your body fat percentage would still be about 12% (20 / 160).
So, your body fat percentage ebbs and flows as you change your body composition.
