How do i gain weight?

Hi, I'm 21 years old and I'm 5ft 6in and have a very small body frame. I was wondering if there is any way I could gain several pounds? I'd like to get up to 110 pounds but I barely weigh 100 lbs, but I've always been very skinny. I am NOT anorexic cause...

I eat all the time and it doesnt seem to help. I eat really big meals too. Should I go to the doctor and see if they can presribe something that will help me gain weight?

may sound nastey but put butter on all your food that is what makes people gain weight

wouldn't it best to remain the weight you are if that's what your natural body shape is? Doesn't seem healthy to put artificial stuff in you, or to over eat. I'm sure your body is perfect as it is.

Thanks. And mmm... I like butter. I probably should stay the same, but I want to get a little bigger. Maybe working out would help?

thats cool that you actually WANT to gain weight and not loose it. I'm 13, 5'1 and 102 lbs. I can't get any skinnier otherwise I won't be able to sit in the passenger seat of a car anymore
