What Is Body Fat Percentage?
Body fat percentage is the proportion of fat in your body compared to your total weight. It’s a key indicator of overall health and fitness. While some body fat is essential for vital functions, excess fat can lead to health issues like obesity, heart disease, and diabetes. Tracking your body fat percentage helps you monitor your fitness progress and make informed decisions about your health.
