How many calories does a 17-year-old need per day?

About 1,600 calories a day, with healthy choices and moderate exercise.

It varies a little based on gender, weight, height, body type, activity level, and a few other important factors. On average, though, about 1,400 to 1,700 calories a day.

It depends on the individual. It's the same thing as asking how many calories a young person needs each day - there's no definite answer.

Most 12-year-old girls need around 1,800-2,200 calories each day. However, it depends on a lot of things, like height, weight, frame size, activity level, etc. That's why it's best to ask your doctor...

It's about 1200. . But If you are athletic, obviously you would need to consume more calories and carbs. It depends on your body type..I would google it and I'm sure there is some type of calculator...
