Anorexia is mostly genetic

People with anorexia have a distorted body image and refuse to maintain a minimally acceptable body weight. Anorexics are about 10 times more likely to die in a given period of time than peers the same age.
A study of twins suggests anorexia is mostly genetic. Researchers compared the disorder's frequency in identical twins, who share all their genes, and fraternal twins, who share half their genes. They deduced that 56% of the "liability" for getting anorexia is genetic.
Conclusions: since the disease isn't "a choice", patients can stop being scolded by doctors, and insurers will have to pay for treatment. Parents don't have to feel guilty about giving their daughter an anorexic upbringing, or blame their parents for passing anorexic genes.

Interesting. You know of any similar statistics regarding food addiction and obesity?

Cause it's not my fault! It just can't be!!! ;-)

Re to ginger blue's comment:
There's recently been a study which suggests obesity is linked to a virus (AD-36). That this virus causes obesity is very controversial, but the virus does seem to occur more commonly in heavier/fatter people.
