The benefit of multi-day fasting versus multiple days of fasts interspersed among days of eating isn't clear to me. There might be some genetic pathways that only get turned on once a fast gets long enough. But there also might be some malnutrition that is harmful (a lack of certain substances that are better if they were around, like vitamins, antioxidants, etc). We know the latter is true of electrolytes, so it may well be true of other things.

So in comparing fast-fast-eat vs. fast-eat-fast, I decided to eat yesterday and fast again today.
