Eating Disorders Support Group
Eating disorders are marked by an obsessive need to control the intake and/or purging of food. This community is dedicated to those struggling on the road to recovery. Join to discuss your experience with others and find support. Get advice, ask questions, and meet others who are going through similar struggles.
They have a tonne of videos where professionals answer questions people ask.
Also, if you have a question that is specific, then you can ask their panel, and they typically (at least, they did for me!) get back really quickly: http://www.findingbalance.com/interact/panel/
There are links to other books and tips on how to help up in the right-hand corner, if you look.
