Great analogy, @GMH! It reminded me of this post on a maintenance blog @SSure told me about: http://justmaintaining.com/2010/09/29/h ... ld/#more-1
Even though I'm struggling, I would say my experience with IF (mostly 4:3) and low-carb has been the opposite of @peebles. In spite of the fact that I don't like carbs much other than having a sweet tooth, I could never sustain a low carb diet for long, and I'd always go a bit crazy when I came off it. I always gained back the weight, usually pretty quickly! IF I've never really found difficult to stick to. I am experiencing fasting fatigue, but I still mostly stick to my fasts. Overeating on non-fast days has definitely been an issue for me, but I've been chalking it up to some personal issues (my contract ends soon; I still haven't figured out what to do next), though perhaps I'm in denial about what weight loss has done to my endocrine system and hypothalamic circuits. Like @carorees, I'll be really happy to see more long term research. In the meantime, I appreciate hearing about everyone's experiences here.
