Oh my god I got to that and just laughed. Laughed so long and so hard. I eat 800 calories when I want to lose 1-2lbs a week, because my bmr is around 1300 and 800 is 500 less than that. However, I always, ALWAYS lose weight because I actually count my calories. I have never put on weight while eating 800 calories because, and correct me if I'm wrong, that's fucking impossible unless you're so sick you don't have a metabolism (i.e. not this fat bitch).
