According to Robert Malina, an expert on childhood growth, adolescents gain weight and height in a predictable pattern, with height growth occurring first, followed by weight gain, or what I like to call âfilling out.â. The average peak height gain in girls occurs between 11 and 13, and in boys between 13 and 15 years of age. The lean tissue (muscles and bones) weight gain during this time is about 15 pounds for girls and twice that for boys (~30 pounds). Girls gain more fat (~6 pounds) on average than boys (~3 pounds) at this time as well. Given these norms for adolescent growth (and the signs that go along with it), you can begin to see that an important transformation happens in teens, and much of it is to be expected.
Healthy Body Fat Percentage for Teens. As a kid, you probably had a body fact percentage of about 18 percent. Once hormones change during the teen years, girls gain more fat, while boys start to build more muscle. Teen girls might add 8 to 10 percent body fat, which they store in their breasts, pelvis, hips and thighs. Teen boys tend to lose body fat as they thin out. Teen girls should strive for a body fat percentage of between 21 and 23 percent; teen boys should aim for between 10 and 12 percent.
