That was how my anorexia began. I purged everything I ate through exercise, but I never did binge, I ate normal meals, sometimes a bit less than normal (but I ate a lot more than others with anorexia tend to eat, it's just I purged it all through extreme exercise). There is also a classification for ED-NOS (eating disorder not otherwise specified); I think I fell under the anorexia definition because my weight was so low.

Yes, I suppose you do have the start of an eating disorder, seeing as your exercise is used to lose everything. Your body needs some of what your burning off, so when you work of everything its almost as if you havent eaten anything. You need to either eat a bit more, or exercise less.

I hope you can maintain a healthy weight and stay healthy

all the best, Natz .x.

Well it's not like I'm burning off everything that I am eating. When I subtract the number of calories that I burn from the ones that I eat it's about 1000 calories. So I am getting enough in (I think).

But the fact yuu are consciously doing this cud lead to an eating disorder. If you carry on you will get worse in this cycle nd it will get obsessive and you will begin to burn more calories than you need and if your exercising that much you need atleast 1500 calories to maintain healthy. Akthough things seem okaii at the moment, after a while it will take a toll on your body .x.

Yes that could be considered purging. There's athletes who burn alot of calories with exercise too (That swimmer Phelps needs to eat 12000 calories a day and hardly keeps the weight on...omg) but you're obsessively exercising with solely the goal of burning those calories, feeling like you /have/ to burn those 750 calories or else...
It's not the exercise itself that can be called purging. Phelps is not purging or exercising just to burn calories, he's just doing his thing as a swimmer because he loves to. It's your attitude and it can lead to an obsessive ED. requiring you to burn more and more and more until something goes wrong (joint damage because of excessive jogging for example).

Exercising to be healthy is good, find a sport that you like and makes you feel good.
Exercising for 3 hours non stop and calorie obsessed is really bad and can get worse. You could try talking to a nutritionist or fitness expert to get some right information about how to stay in good shape.
