Active Teens: Fitness & Nutrition for Growth

Puberty and Body Composition

During the teenage years, hormones cause significant changes in physical development. Boys often gain more muscle mass and lean tissue, while girls typically gain more body fat around the hips and thighs. These shifts can cause sudden increases or decreases in BMI that are perfectly normal and healthy.

Growth Percentiles for Teens

Like children, teenagers' BMI is compared to national averages for their specific age and sex. A teen whose BMI is at the 60th percentile has a higher BMI than 60% of their peers. Only a healthcare professional can determine if a teen's BMI is healthy given their overall growth history and development stage.

Focusing on Health over Numbers

For teenagers, focusing on weight alone can be counterproductive. Instead, emphasize these healthy behaviors:

  • Stay Active: 60 minutes of physical activity daily.
  • Balance Nutrition: Whole grains, fruits, vegetables, and lean protein.
  • Sleep: 8-10 hours of sleep per night is essential for growth hormones.
  • Self-Esteem: Bodies come in all shapes and sizes. Visit our Teen Fitness guide for positive movement tips.
