This is potentially lifesaving insight for anorexia sufferers. I'm just starting to try this approach for myself after 30 years of battling this. I finally feel understood by an article describing the 'addiction' like effects of starvation because ketones feel so good. I feel great with a good level of ketones. It definitely is the reason I keep going back to the anorexic behaviours - that and other effects that create the feel-good benefits such as endogenous opiates, increased parasympathetic activity. And in all my years of treatment, noone has ever suggested this approach. Thank you. And I'll be spreading the word about this.
