I eat only one meal a day (normally a few bites out of a sandwich or maybe like a few noodles). I do not sleep either. I haven't really closed my eyes in a week or two. I'm not afraid of becoming fat at all. I just have no compulsion to eat a lot, and I become full fairly easily and/or sick of the same flavor in my mouth while eating a meal and not wanting to finish it. I do not throw up after eating either. It's strange. I'm 5'9" and probably around 100 lbs. My family is all skinny people, but I'm a new low.
