I'm 5'11 and only weigh ~130lbs.
I'm tall and skinny. I eat a normal amount of food, I'm healthy, and I'm semi-in shape. I was skinny throughout my life, tried the asian method of weight gaining as my parents made me drink some absolutely disgusting tea that no one should ever have to drink unless as punishment, and I go to the gym occasionally. I don't really care, I'm healthy and I bet I'm more in shape than most people.
