a...r...CRAZY???, you'll make things worse by limiting yourself to 450 calories, cuz then your body is going to make the food you pigged out on today into pure fat because you didn't get enough calories to get you through the day, it'll make things worse, believe me. I know you must be feeling really desperate, angry at yourself and very sad for whats happened. But don't worry, were all human, mistakes like this are supposed to be made,you have to goof once in a while to bring you back to reality. The excercise thing is cool, but not limiting your food. Be healthy...my parents yelled that at me and rammed it down my throat cuz they could see i wuz almost developing an eating disorder, piggin out and then trying to do what you want to do the next day. Now im back to normal, eatin 1,200 cals a day, and losing weight! Reason is, im eating healthy and excercising.
