Like obesity then...
The 60s and 70s saw the same groups clamoring at the "nurture" end of the nature/nurture argument. Now, they are attempting to swing bedside to the nature side. No doubts BF Skinner is having a cow out there in "outer body" land.
( An international study concludes that the eating disorder anorexia nervosa, a rare but dangerous mental condition, is primarily genetic in origin.)
Alcohalism,obesity,homosexuality are now considered to be genetic deficiencies and not choices anymore by the dufus intellectuals. Next step will probably be "fixing the parents" to create a master race of liars and killers [once called national socialists (nazi's) in the 1930's]. And their banner is atheistic socialism all done for love for the children they so relentlessly murder in these times of sorrow.
This is an important article, but it is only the beginning. My daughter became anorexic when she hit puberty and her biochemistry and hormones went all out of whack. When we got her various chemical levels normalized - female hormones, blood sugar, thyroid, etc. - she was ok.
I believe it is essentially a biochemical disorder, which certainly can be strongly impacted by heredity. We went through hell on earth until things were fixed. Even now, she is very brittle - she has to make sure she gets precisely enough water, she has to talk salt tablets, and regulate her blood sugar levels through eating small meals at precise intervals. Her grandmother has the same biochemical issues.
Some people may choose to diet too rigorously and it gets out of hand, but even then they set into motion some of the same biochemical issues that happened to my daughter "naturally" in puberty. Once your body gets off balance like this, for whatever reason, it still needs to be brought back somehow or it can be fatal. When the doctors treat it as a "psychological" issue only, these poor people can't get well!
