If you hate your body, the way you look, and you're weight, then yes. You are at risk of having an eating disorder as the results said.

Typically a full blown eating disorder is evident when someone
1. Eats less than what is required to sustain weight and becomes notably underweight.
2. Binge eats and then purges.
3. Alternating between binging, purging, and not eating.
3. A combination of these things accompanied by an obsession with working out, and other methods of weight control aside from just purging. (such as taking laxatives after meals).

There is an obsession/compulsion about it and they act on it.

I feel that if you took that test some part of you felt like there is a possibility of having or starting to have an ED based on your habits or how you have been feeling about your body.
