Is this normal (Dietary Habits)?

I would presume I have a problem and this is not normal but, In the past 2 weeks Ive barely eaten anything (I know how dangerous and unhealthy that is) but I just haven't been hungry, but I find myself full of energy for some reason? I'm 14 years old and 6'2 185 lbs if that helps at all. I'm still optimistic and full of energy so whats going on?
