My feeling (read this as 'a gut hunch based on no actual research') is that cyclical diets (of any sort) do tend to at least 'slow' some of the metabolic adaptations. But I'm not sure that they eliminate them completely. What they might do is allow people to go a bit longer before taking a full break.
Do they eliminate the need (psych or physiological) for the break completely? Maybe....
Lyle, this question was posed to you a few years ago, any new thoughts on it now? I ask because I was running a diet with 3 weekly refeeds, hunger wasn't much of an issue and maintaining weights in the gym was a breeze. Took a break after 6 weeks (in the middle of the break now) simply because I didn't want to go 12 straight weeks dieting.
