I found this article on a Swedish method of treating anorexia:
They consider the illness just as an eating disorder and not a mental illness. They treat AN by normalising eating behaviour. What was interesting for me about the article was that they considered excessive exercise due to dieting to be hard wired in the brain. Here are some quotes:
"The approach is based on the theory that slow eating and excessive physical exertion, both hallmarks of anorexia, are evolutionarily conserved responses to short food supply that can be triggered by dieting - and reversed by practicing normal eating."
' "This new perspective is not so new: nearly 40 years ago, it was realized that the conspicuous high physical activity of anorexia is a normal, evolutionarily conserved response - i.e., foraging for food when it is in short supply - that can be triggered dietary restriction.
"In striking similarity to human anorexics, rats and mice given food only once a day begin to increase their running activity and decrease their food intake further to the point at which they lose a great deal of body weight and can eventually die."
"More recently, the theory has been elaborated and validated by studies of brain function."
"We find that chemical signaling in the starved brain supports the search for food, rather than eating itself," reports Sodersten.'
D became obsessed with exercise at age 9 and started eating 'healthy' at age 9.5. Restricting couple of months later. IP for 2 weeks at age 10. Slowly refed for months on Ensures alone, followed by swap over with food at a snails pace. WR after a year at age 11 in March 2017.
