Having done both time-based and food-based restrictions, I would say that both can work for some people but won't work for others. And I think the details matter a ton. E.g., I've happily done months of fasting where my eating window is circa 7a-1p. But I spent a month trying a switch to a 12p-6p so I could eat dinner with people and it was hell. I got mean in the 10a-12p range and that did not improve over the month.
