Okay guys....I used to be anoerxic too (and bulimic for that matter, but that's a different story...) and the whole starving yourself/gaining weight thing is true. The first time you do it, your body will accept it and you'll lose weight. HOWEVER, you can't do use it as a short term weight loss plan, and then start eating again once you lose the weight. Also, when you do start eating again, slowly raising your calorie intake won't help either, because no matter how gradual it is, it will all be stored as fat. It's a nutritional fact that after 5 hours without food, enzymes that store fat will start to grow and strengthen and multiply. They eventually become like a big army, and absolutely everything that enters your body will be stored as fat. Even water helps the lipid bonds (aka. fat cells) strengthen. Since your body thinks that you are actually in significant danger (stranded in a forest without food or something along those lines), it stores fat to keep you alive, as if you were going into hibernation; eventually your body will slow down and you will only be able to sleep, when your body will FINALLY take a stab at your fat stores to keep you going, since you've physically stopped. Now once these fat bonds are strong, your enzymes are working hard at storing fat, and your energy level is down, it becomes nearly impossible to actually lose any weight, even by exercising. Adrenaline and negative motivation can keep you going for awhile, but it REALLY is not a good long term alternative. Rather than trying to be waif thin, try to be leaner...do weight bearing exercises like lifting weights, situps, pushups...not excessively, but a decent amount. The more muscle mass you have, the more calories you burn, just by sitting there. Someone with a lot of muscle can sit on a couch watching TV and burn 5 times more calories than someone who is as skinny as a stick with no muscle and is sitting on a couch watching TV. So Sarah, THAT is what all the talk is about with people gaining weight when they starve themselves, and I hope you guys are all a little bit more informed now. Also, please take what I'm saying seriously, I was hospitalized 3 times for my eating disorders and I'm in therapy...it's SO not worth it for a few pounds. All of this info came straight from a nutritionist, so it's 100% true and trustworthy
