What are the average body composition for teens?

Average body composition for teens can vary based on factors such as age, sex, genetics, and activity level. Generally, healthy body fat percentages range from about 10-20% for boys and 15-25% for girls. During adolescence, body composition also changes due to growth spurts and hormonal changes, with increased muscle mass in boys and higher body fat percentages in girls. It's essential for teens to focus on overall health rather than specific body composition numbers.
