CMV: Fasting is NOT an Eating Disorder

So I started intermittent fasting about a month ago. I feel much better, didn't know I was so bloated until I took a three day break from food initially. I have problems with eating way too much at once, even if I don't want to. It's called binge eating, and I WOULD consider THAT an eating disorder.

People in my life are now saying I have a problem. My skin is clear, I've lost weight, I feel I have control over food for the first time in my life, and I'm not going to stop doing this. However, a lot of people consider not eating a horrible idea. That it's an eating disorder or can at least lead to an eating disorder.

Nobody ever said I had a problem when I ate crazy amounts of fast food, many days eating more than 4,500 calories minimum.

So hopefully someone can change my perspective a bit? I know it could lead to an eating disorder, but is one disorder somehow worse than the other? Why is overeating so acceptable but undereating is unacceptable? I stopped talking about it and avoid the questions because no matter how well someone knows me, they feel perfectly comfortable telling me how awful it is to skip meals.

All I know is that when I ate regularly I couldn't control the quantity. When I don't eat, I feel better and have only experienced positive effects.

Edit: Assuming that I'll develop anorexia from fasting is an overreaction and is the problem I have with the people in my life. It happens, but not to most. There is no evidence as of now that I will become anorexic. Also yes, I am biased with my appearance but I am not making up that I'm too fat. My doctor said I'm obese. It's not a matter of body image problems it is measured and factual.

Overeating is an eating disorder. Undereating is also an eating disorder. 

In particular, anorexia is characterized as a means to gain control of at least part of your life, when otherwise you lose control.

Also, anorexia is characterized by having a distorted body image. Seeing themselves as fat, even though they are severely malnourished.  

Fasting to lose weight is good, if you are currently overweight. Fasting to lose weight, when you are already underweight, is an eating disorder. 

The key difference is a neutral third party view of a healthy weight. There is a healthy range of weight, for a particular height and age. Being outside that range, either above or below is bad. 

Just make sure you are seeing your doctor every once in a while to make sure you haven't lost an unhealthy amount of weight. It can be hard from a first person perspective, since distorted body image, is one of the signs of anorexia.
