Slightly bloated stomach?!

Slightly bloated stomach?

I'm almost 17 (male), and have been eating a lot the entire year, and i am skinny (high metabolism) and work out, run etc, 6'0 and 150 pounds if it makes a difference. recently though, i feel like i have been gaining a more bloated stomach, but my eating patterns have stayed the same- i havn't gained any weight, and ontop of that, i just added running to my workout about 2 months ago. When i look at my stomach, it looks muscular, but just bloated.. does anyone know if it could be a food allergy or something?

Could be you are eating something that your body has a hard time digesting. So men and women (although unfortunetaly not many women) who are really really skinny just wont gain weight in the right places. When they are trying to gain weight.
How are your bowel movements? If they are normal then try to cut out some bread and pasta's that you are eating, if your eating a excess of them they will bloat you.
Try red meats (they are extremely important for men to eat, since they have male hormones in them, and lots of fruit and veggies, that way you may in fact gain the weight in the right areas, People always think carbs carbs carbs when putting weight on, usually they are only eating empty carbs and cals.
