how many calories should a 12 year old consume in a day
Depends how tall you are...
I wish I had an easy answer but I don't. However, mypyramid.gov has great tips and tools to eat well and tell you how much and what kinds of foods you should be eating, even at the age of 12.
2000 a day no more then 2500 if your active
2,000 for a relaxed day. 2,000- 2,500 if you are active
I think a lot of that depends on your height and weight
I think 2250.
It depends on your height, weight and your active level. If you play sports. When you are young and still growing you need more calories. My son is 14 he is 6'3 and weighs 240 and plays football. He is eating about 4500-5000 calories a day.
