Tips on how to become an anorexic
There's plenty of ways to stop eating, but here's some advice on how to do it properly without seriously hurting your body in the process. I'd say it's more like fasting as there's no way I'd actually recommend being anorexic for a long period of time. It's not even good for short term weight loss unless you'll be changing your life afterwards... and if you do it for too long, your body will start storing energy and water thinking you'll be without food again for quite awhile, increasing your weight/fat storage in preparation.
Anorexia is a psychiatric illness that describes an eating disorder characterized by extremely low body weight and body image distortion with an obsessive fear of gaining weight [taken from Wikipedia]. Do you really want that? If so, you might as well do it in a more healthy fashion than the high school girls who don't eat anything. And don't even think of being the type that releases their lunches in the bathroom stalls immediately after eating.
While you don't have to eat if you want to become anorexic, these aren't tips on how to kill yourself or lie in bed all day out of energy. The easiest way to have your body feel full without starving pangs all the time is to still eat some foods that fill you up. With the right plan it could be a great way to lose weight as long as you only do it temporarily, but you're going to put on the pounds again afterwards if you don't change your exercise or eating habits.
The first thing you should do is make sure you drink a lot of water. Stay hydrated. But don't drink too much water, that could cause you even more health problems than anorexia. People can die from water intoxication. There are a lot of staple foods you can eat that are very low on calories, but tricks your body into thinking it has enough energy to carry on the day.
Celery, several other vegetables, and rice are good to eat plenty of if you want to become anorexic thin without killing your body in the process. Watch out for the salt as consuming enough of that will increase your water weight and cause other problems. You should also try to get plenty of cardio exercise. Swimming and running will do the trick. One more thing you should be aware of: Being anorexic to the point where you're super skinny will lose you most of your breasts. You'll also have people scared to hug you as they'll feel your bones pressing against them.
Whatever choice you make, please do not become anorexic for a long period of time. It's not healthy at all.
