Well, I wasn't thinking of fasting, just wondering about the day-after-day calorie count being lower than my Cronometer macros.

I tried fasting back when Dr. Fung first made a splash and half my hair fell out (and I wasn't even doing more than OMAD and maybe a 24 hour fast once in a while) so it was obvious that I wasn't able to get enough protein on that regimen.

Interesting about blood glucose lowering after protein eating. Sometimes I have a Greek yogurt while I'm trying to decide what else to eat which may take up to an hour, especially if I decide to actually cook something, so I guess that would qualify.

I've read quite a bit of Marty Kendall's stuff but am not inclined to do the actual DDF. Maybe one day.
