Hey,
well by reading your post it sounds like you are just growing right now. At age 15 your body needs a lot of food and feeling hungry all the time is something normal for people your age. After all you are a teenager. So I wouldnt worry about it too much...If you are really that worried maybe you could see your gp but I think you're fine.

I'm not sure if you're a girl. Because if you are it coulad also be caused by the chnages by your menstrual cycle.

I hope this helped, i'm not a dr or anything, i'm about your age (i'm 17) but this is just what I know. Hope I helped even a little. Take care.

The same thing is what happens to me. I will eat like a whole munch and then when I am done eating a lil while lata I feel like I had eaten nothin at all. I am 15 and weigh 115-120(changes every day). I ask friends that r the same age and they don't have this prob. At first I thought I was the only 1 but I guess not but none of my friends do. So, I didn't really help u but, u r definately not alone wit this :!:

Look, it can be normal. It happened to me and it sometimes happens that too. It's a matter of our own metabolism... It will end up working his way, so we just gotta listen to it and treat it right, trying to inderstanding it the best we can. Ok?

I don't think that having products is the way, unless it's medication prescripted by a doctor. :p
