My brother has been this way for a long time. He doesn't eat any meat and isn't a vegetarian. He eats cheese pizzas, fries, breadsticks, and foods like that. He will not eat fish, chicken, or any meat. He has tried pepperoni. I mean he usually eats only cheese pizzas for his large meals. If we were to order out it would also be a cheese pizza. He liked pancakes and waffles. I've asked why he eats that way and he really never says. He's been like this since he was little. My mother said he ate baby food. When he started to get older he didn't eat meat or any of that. What could be wrong with him? I don't think he'll change the way he eats. He had a girlfriend and she couldn't even change him. I'm mostly worried about his weight and he is skinny. He's not disgustingly skinny. It's like weird to me cause I eat way different. It's a weird diet and I think he might have problems when he gets older. He doesn't eat fruit, vegetables, and his food groups aren't good. He likes mozzarella sticks and dips them in sauce. I know if I talked to him he probably wouldn't change his eating habits. So far he's been healthy and is at 160lbs or a little more. He's also taller than me about 5'11. It's just a very weird eating style he has. Another thing he eats is Peanut butter with no jelly on bread. I'm not exactly sure when all of this started or at what age. All I know is he eats a lot of cheese pizzas and he doesn't like meat or anything. I mean if we went through all the food groups I could name what he likes and eats.
