What is a healthy body fat percentage?

For men, a healthy body fat percentage is typically 14-17% (fitness range). For women, a healthy range is 21-24%. Athletes tend to be lower: 6-13% for men, 14-20% for women.

How is BFP different from BMI?

BMI only considers height and weight, so it cannot distinguish between muscle and fat. BFP directly measures body composition. A muscular person may have a high BMI but a healthy BFP, while a skinny-fat person may have a normal BMI but a high BFP.
