What is the daily intake of calories for a typical teenager?

It depends on the teenager. Everyone's bodies are different and some people need more calories than others. But if you want a definit answer the average calorie intake a day is around 2,000 calories. But keep in mind some people need more than that to keep the nutriets they need in their bodies. Don't obsess about calories or food, it's good to count calories but don't obsess. Eat healthy but once in a while it's okay to indulge in that special treat. (Just eat in variations)
