What shall I do?

Really?? No.

Yes mate, you certainly can. If I was you, I would just hang about for a few days and lurk on the threads, have a look at some people's diaries and see what they eat and the exercise they log. Starving yourself won't help you at all.

Once you get some idea of how things work around here, start having a look at nutrition information and exercise plans and stuff.

A lot of the people on this site will tear you to pieces as soon as look at you when they read a post like this. Just lurk, and watch for a bit!!

Think of this as a long long journey. nothing at all will change overnight. If you have a chocolate bar you won't explode, and if you run 100 miles a day for three weeks, then do nothing, your weight won't change.

It's a long journey, good luck.

You have an eating disorder.

Please seek professional help as soon as you can.

You are setting yourself up for a perfect program of weight loss.

You'll lose some fat and muscle, probably 50/50 with that extreme a deficit.

With that much less muscle, your metabolism will plummet.

You'll also be living with depleted glucose stores along with associated water, and with muscle gone less room to store it anyway. That also lowers your LBM, and lowers your metabolism.

You'll also being lowering your metabolism because your body has to for the limited energy it is getting from your food.

So now you'll lose weight, all good beneficial needed weight (might as well just cut off a leg and arm actually) that keeps your metabolism up.

With a metabolism that low, if you have a vacation week, or a big family meal, or the binge we know is going to happen eventually, you'll put on fat mostly from those times.

If you actually reach goal weight (big if), you won't be able to eat much more, if you do you'll gain more than just normal water weight, you'll gain fat. And that will likely happen slowly but surely.

You'll repeat this in 2-3 years to lose the same or probably even more weight now.
But with less muscle mass, you'll find it much harder to do.

You'll end up 50 years old wondering why you've wasted your life away with yo-yo diets and being super concerned with food, real unhealthy relationship.

Ask many of the women on here how it feels to reach older age and realize what you've done to your body for most of your life. You can read their comments all the time.

Yes, you are setting yourself up for a perfect weight loss program. I mean, for all the businesses selling weight loss products to what will be a long-time customer.

So I'd actually lose MORE weight eating 1200 instead of 800?

Well, you'll probably lose LESS muscle mass. Eat to fuel your body. Find a calorie calculator, say you want to lose 1 lb a week and letit tell you how much to eat. Food is not the enemy. You've traded one bad extreme for another.

Hopefully they realized that despite being in college, they were ignorant about how the body works.

actually, at a certain point, ignorant isn't the word either ...

That is so unhealthy as to be seriously dangerous. You attend college so you need to go and speak to a nutritionist at your school, which should be free.

First, you are doing a disservice to your body by not giving it the protein, vitamins, overall nutrition it needs to survive.
Second, any weight loss you will have will likely not be lasting, as when you start to eat again, and you will, your body will immediately put on fat since it will think it will have to do this to survive another starvation episode, such as what you are doing now.

You need to EAT! But eat HEALTHY! You can eat over 1200 a day and it can be very healthy. In fact, you can eat 1800 calories a day and be healthy. Your are still young, and actually likely still growing in some ways, so you need to make sure you EAT a full and balanced breakfast, lunch and dinner. Even if you eat a protein bar for breakfast, you need to eat something.

While I think this might be a not so genuine post, if it is real, you seriously need to talk to someone who can help you lose weight in a manner that will allow you to keep it off, someone who can help you make a SUSTAINABLE life style change for the better, which does not include what you are currently doing. If you keep doing what you are doing, you will likely damage your body and your metabolism.

U know you need over 1200 cals a day
anyone does

Wow it must be so nice being cleverer than everyone else. What a bunch of idiots.
