Help! Gain weight won't stop

But why am I gaining weight right now even if I eat no more than 1200 calories?

Based on your height, 1200 calories may not be a deficit sufficient to cause weight loss. At 5'2" it may be closer to what your body generally NEEDS on a day to day basis.

But why am I gaining weight right now even if I eat no more than 1200 calories?

Hey there! Wow,34 pounds... that sounds scary. Honestly, anorexia is a constant cycle, and you don't want to get stuck in it. If you were eating really little and became anorexic, and then gained weight, and now are eating under 1200 calories again, you're just going to send yourself back into the anorexia can't stop restricting and can't stop losing weight mode. I know it must be irritating to you that you're above the weight where you started, but before you try dropping just a few pounds, I would definitely wait until your body is back to normal again. Try to maintain for at least a few months first so your metabolism gets working normally again, your health and hormones are all back to normal, and you get your eating under control. I'm not sure if you knew this, but if you eat too little, your body will gain weight. You can see for yourself many people on MFP have said when they've restricted too much they've gained, and when they increased their calories they actually lost. I know that might sounds weird to you, since you ate really little before and managed to lose weight, but you have to understand that your metabolism is all out of whack right now, and besides, that's not a healthy way to lose weight. For now, eat about 2000 calories a day for a couple weeks, and see if you gain any more weight at the end of those couple weeks. Chances are your body's going to need every morsel of that food and you're not going to gain more than a pound in that time. (Now, I had a friend who had anorexia, and when her dietician boosted her to eating 2000 calories a day from her previous 1000 she obliged, however, she weighed herself the next day and was concerned that she gained two pounds. Weight fluctuates based on the last time you used the bathroom, how much you drink etc. so don't weigh yourself right away and then go back to eating ridiculously small amounts of food because you think eating 2000 calories a day will make you gain 2 pounds a day. It won't. It'll replenish your body of nutrients lost and won't be enough to make you gain. It takes 3500 calories extra for one pound of fat.)

Anyway, my number one piece of advice for you right now is to try to eat normal- try not to restrict and try not to binge. Aim for a healthy 2000 calories a day for a little while until your body gets back into sorts. Please don't put it into starvation mode again by eating 600-1200 calories- whether you believe in it or not, though I saw my friend first hand in starvation mode... Even if you don't believe in starvation mode, that number of calories daily still isn't healthy since you'd beat eating below your BMR which is the minimum number of calories needed to keep your heart, liver, brain etc. functioning properly. That's why anorexia is so fatal; when you aren't eating enough your body doesn't have the energy it needs to keep your organs working efficiently, organs fail, and after putting yourself through that for long enough you can wind up dead. It's scary, really. I know the cost of a dietician might be a little expensive, but I also suggest just try setting up a few sessions so you're at least heading in the right direction.

Good luck! Try not to fret about weight gain right now; you were almost dead- you said it yourself- so the way your body responds to food right now is way out of sorts.
