I'm hungry.
I eat like a pig. I eat whatever I want, whenever I want. I usually eat something about every hour, but the quantities differ. I'm constantly drinking something, usually a soda like dr. pepper. Normally people would love being in my situation, eating as much as they want without gaining a pound. But I hate it. I'm 110 pounds and about 5'9. I'm fifteen so I think a high metabolism is normal. But when people say I'm so skinny, I take it more of a insult. I want to gain at least 20 pounds, and be like a size 5. I'm a size 0. ): I hate it. I cannot gain weight no matter what I do.
Start a fitness plan that includes weights. You'll define your body more and muscle weighs more than fat so you'll gain weight but it will be distributed nicely.
I agree with the other commenter lol. I used to be that way too when I was a teenager. Now, 10 years and 3 kids later I am trying desperately to LOSE weight. Enjoy it while it lasts because eventually you will gain weight and you probably won't like it as much as you think you will :-)
Been there, done that. Don't worry it won't last. LOL
