I know its unhealthy, but what will happen?

So on friday I binged REALLY bad. We're talking around 3500-4000 calories or something. So on saturday I didnt eat ANYTHING and I mean nothing. I had like coffee and diet sodas and that was it. I know this is really unhealthy but I felt so guilty from the night before I couldnt bring my self to eat anything.

Now today I've only eaten somewhere around 500 calories and I was wondering should I stay below 1200 calories today, so I dont shock my body and make it gain everything I eat, because it thinks I wont get any food later?

and tomorrow I'll up it a little bit more?

I just dont want to gain weight by immediately by going back to my regular calories so what should I do?

Here's what will happen

Obesity on 700 Calories a Day

Read the entire article, even if you don't resemble the hypothetical woman.  Especially read the points the author makes at the end.

That is a GREAT article! Somebody should post that every day! I would just go with the 1200 today and keep with it (maybe even more if you need it). You don't need to up it slowly. It was just one day. Some people fast for a few days. Consider it a fast and get back to normal NOW. 

First off honey, relax.  Everything will be all right--If you deny your body the calories it needs to survive, you are more likely to have episodes of uncontrollable eating.  1200 calories is what the average body needs to function--you need more than that to be healthy, and I think you know that.  If you are hungry, eat, and if you are not, then don't--but don't starve yourself, and try to eat enough to keep your body healthy.  Just like one bad day won't put on pounds and pounds, going in the opposite for a day or two won't balance it out.  Just go on today, and don't dwell on yesterday--it's done and you can't change it.  Good luck to you--

My goodness!  You're no calorie day was a worse thing to do than your big calorie day.  You're body needs fuel to run itself, please don't starve yourself for any reason. 

I think you need to take things a day at a time.  Yes, binging isn't going to get you to your goal, but neither is starving for a few days after binging.  If you have a big calorie day, so be it.  Treat the next day as new, and eat what you are supposed to eat to have a healthy calorie deficit, (500-800 calories).  Don't try to "make up" for one big calorie day by having several low or no calorie days.  That's just going to exasperate the problem and keep you in the habit of drastic calorie level changes from day to day.  You're body will work more efficiently and burn more if you get it into consistent habits.  Try to keep your calories consistant from day to day, and if you have a high calorie day, don't freak out.  Start fresh the next day with a normal calorie day, not a low or no calorie day.  Drastic changes like that can't be good for your metabolism.  Feast and famine just doesn't cut it.

The easiest thing to do, of course, is to try not to binge in the first place.  But we all know that!

ok I think I'll eat up to 1200 today

Thanks so much everyone

you helped out tons :)

foysause, in my opinion, it was a reasonable response to the bad binge.

and, clairelaine, with all due respect, abstaining from food one day is not the same as a 700 calorie a day diet. 

I want to second the one day at a time advice.  Please consider two things.  First, one meal more or less is not going to change your weight. 
Second, the natural way to control your eating is use your hunger.  Eat when you are hungry.  Don't eat when you are not.  Of course, the problem with that approach is conditioning.  If we are conditioned to eat 3 times a day or 6 times a day or when we are emotionally distraught, or mixing socially, etc., then we will eat in those situations whether we are hungry or not.  So you need to learn or re-learn to use the natural signal to control your eating.

Finally, your profile indicates that you are active -- swimming, dancing.  Please make sure that you are getting enough nourishment to fuel yourself through those activities.
