Are calories good for health? Why or why not.

Thanks Alot!

Like fuel for a car, you need calories to function. However, when you take in more calories than you use, they are stored as fat. If you store too much, then this can be a problem.

Since this is not my area of expertise, I searched Google under the key words "calories per day" to get this:

This should give you a start.
