A healthy body fat percentage for adults typically ranges from 18% to 24% for women and 10% to 20% for men. These percentages can vary based on age, fitness level, and individual health goals. It's important to consider that body composition matters more than weight alone; a healthy ratio of fat to lean mass is crucial for overall health. Excessive body fat can raise the risk of chronic diseases, while too little can also be harmful. Regular exercise and proper nutrition help maintain a balanced body fat percentage.
