🔍 What Is Body Fat Percentage?
Body fat percentage is the proportion of fat to your total body weight. For example, if you weigh 150 pounds and 30 pounds are fat, your body fat percentage is 20%.
🎯 Ideal ranges
- Men: 10%–20%

Having too much or too little body fat can negatively affect your hormones, metabolism, heart, and overall energy.

\text{Body Fat %} = 163.205 × \log_{10}(\text{waist + hip – neck}) – 97.684 × \log_{10}(\text{height}) – 78.387
