You use two phrases; "throw me" and "back on track" - could you elaborate a little. I'm not exactly getting what you're getting at.

Carbs aside, are you taking about something like:

0 calories day one, then 4000 calories day 2 = 2000 calories day 1, then 2000 calories day 2 ?

If I'm eating LCHF, like I am doing this November, and over eat on Thanksgiving (but remaining LCHF) I typically will really pay attention to my appetite the day _after_ and if I'm not hungry, I'll try not to eat out of habit. I don't think I usually fast before feast in a planed manner. I could see that kind of pattern being promoting overeating more often for myself - As I could start to mis-interpret my normal appetite - which I barely have a handle on to begin with as far as knowing what hunger is.

Thanks for bringing up a interesting approach and perhaps someone might think it taboo
