A healthy percentage of body fat for men typically ranges from 10% to 20%, while for women, it is generally between 18% and 28%. These ranges can vary based on factors such as age, fitness level, and individual health goals. For athletes, lower percentages are often seen; however, it's essential to maintain a level that supports overall health and well-being. Excessively low body fat can lead to issues like hormonal imbalances and decreased bone density, while excessively high levels can increase the risk of chronic diseases, making awareness of these ranges important.
