A very non-veggie Japanese teen - a healthy diet?

DIET

I think my diet is bad. I'm not a vegetarian. I don't usually eat vegetables because I don't like them. I like unealthy food, which have have a lot of calories.

HEALTH

I think I'm healthy. I don't get many colds or fevers. I sometimes get headaches, but that's when I'm very hot.

EXERCISE

I don't follow an exercise proram. I have to take three hours of P.E. every week at school. I should do more exercise.
