Teen training needs enough food

The key question

Adolescence combines activity with ongoing growth. NIDDK explains that energy needs vary with age, body size, growth, and activity, and discourages unhealthy weight-control approaches. An adult calorie-cutting challenge is not an appropriate default for a teenager who trains. Meals should supply varied nutrients rather than revolve around a single protein product. Changes in eating driven by shame or pressure deserve a supportive conversation and, when needed, qualified assessment. [1] [2]

Making activity sustainable

Physical activity includes transport, work, play, and planned exercise. Guidelines distinguish aerobic activity from strengthening and balance, and adapt recommendations to age and health. A weekly plan can start with manageable opportunities and progress gradually. Fitness is not measured only by body weight, and a demanding session is not the only useful session. The relevant comparison is often with your own starting point, rather than another person’s performance. [2]

Putting it into practice

Prioritize regular meals and involve a trusted adult and health professional when training and eating become difficult to balance. [1] [2]

General activity guidance is not an individualized rehabilitation or pregnancy prescription. [2]
