I have no idea if I actually heard this somewhere, from Leigh or otherwise, but I think it makes sense for ED recoverees to avoid HIIT, if only because it seems like it could easily feed into the negative mindset. Then there's the fact that high intensity work, albeit "short term," is still a stress on an over-stressed body.
And this is sort of off-topic, but I just finished listening to the audio version of Leigh's new "Ask Leigh" book. I know she talks about having people think back to when they were successful with fat loss and remember what worked for them. My most successful term of fat loss was when I lived in Chicago and had no car. My only official exercise was at Curves, so that was low-grade stuff, really. Aside from that, I walked and took the stairs (had a job on the fourth floor of a building). I'd never heard of HIIT or afterburn effects or anything like that. My weight loss was consistently 2 lbs/week, so that seems to indicate to me that my body likes lower-grade stuff, just a lot of it.
