A quick follow-up question:
I've read that it's good to eat post-WO to decrease cortisol levels.
Why should we not be concerned about this if we IF, workout outside the feeding window, and wait many hours before eating? For example, several of my workouts lately have been at 11-12 at night and I didn't eat until 1-2pm the next day.
Actually, why should we IFers not be concerned about cortisol in general (as compared to folks who eat normally)? My limited understanding is that cortisol levels are kept under control partly by regular eating.
