How many calories per day for a teenage boy?

The amount that should be consumed varies from person to person. For example, it depends on such things as your height, weight, age, activity levels, lifestyle, gender (male, female), and whether you need to lose weight, maintain weight, or gain weight.

I am a 17 year old male, and eat a large amount of calories per day (approximately 4,000 calories). I am not overweight, but I am very physically active. If you record how many calories are burned a day, then it is easier to determine how many calories you need. If you eat more than you burn, weight will be gained. If there are less calories consumed than used, weight will be lost. If they are equal (approximately) then there will be no major weight change.
