LOL Your posts made me laugh!!! "I'm onto you, skinny girls!"
I know ONE skinny girl that eats like a beast!! no joke!! it's amazing. I hope it never catches up to her but dang does she put food away!! Hahaha Most of the skinny girls I know don't eat that much though, I agree.
I think they either have little stomachs that can't handle much food, or maybe they just eat little amounts like that but all day long? I dont know.
I started lately only eating about half my plate. Intentionally. I actually convince myself that I'm done. It's hard, but I don't regret it after the waitress goes away with it.
