Poking around the web reading a bit more (as I said, I don't have access to the books), I found info about the "famine reaction," which I recall reading about on the forum. I have certainly experienced this, especially when on very restrictive regimens (Atkins, the Zone). However, I have not had that problem while on 5:2, even though I've plateaued (which I interpret as my body getting "used to" being at a lower weight). I think this may be because I DON'T restrict myself on normal days; I pretty much eat what I want. But since I've never been prone to binges, I guess I don't have an issue with that. Sure, I'll sometimes eat more ice cream than I really "need" (yeah, though we don't "need" ice cream from a physiological standpoint, psychological is another thing!), but I seldom stuff myself...just don't like being overfull! And as I've said before, as a vegetarian who eschews fast food (and HFCS, artificial sweeteners and colors and flavors....), my diet is pretty healthy. My point is, since I only "starve" myself 2 days a week (sorry, but it sounds like some of you do it most of the time), the famine reaction never kicks in. (And yes, I know this is an anecdote of one, not scientific at all....)
@Sallyo (and others of us who are "older"), have you read about the research saying now that a higher BMI (they say 27.5) is healthier for older women?
