How can I determine how many calories my body needs per day to neither gain nor lose weight?

How can I find my basal metabolic rate?
Multiply your body weight by 12 if you are a man; 11 if you are a woman.

How can I determine the number of calories I burn through activity?
Multiply one-third of your body weight by the number of hours in which you don't sleep (usually around 16). Add to this the calories burned through an exercise program.

Add your basal metabolic rate and calories burned through activity and multiply by 10%.

No. Young people have higher basal metabolic rates. Creating diet plans for teenagers is a bit more complicated than for adults and should only be done with the aid of a physician.

You don't need to keep track of everything you eat, but avoid fatty foods and empty calories in drinks. Couple this sensible eating with exercise 3 days a week and you should stay slim.
