What is Body Fat Percentage?

Body fat percentage is the proportion of fat in your body compared to your total body weight. Unlike BMI (Body Mass Index), which only considers height and weight, body fat percentage takes into account actual body measurements, making it a more accurate indicator of fitness.

Healthy Body Fat Ranges:

Men: 6% – 24% (athletic to average range)
Women: 16% – 30% (athletic to average range)

Higher body fat levels may indicate increased risk of health issues such as heart disease, diabetes, and obesity-related conditions, while very low levels may also affect hormone balance and energy levels.

Why Body Fat Percentage is More Important Than Weight

Many people rely only on weight to measure fitness, but this can be misleading. Two individuals with the same weight may have completely different body compositions.

For example:

A muscular person may weigh more but have low body fat
A less active person may weigh less but have higher body fat

That’s why body fat percentage is a more meaningful health indicator.
