I do continue to lift although I am not nearly as productive in the gym as I'd like.
I haven't had any issues with reintegration of food but I take berberine 1g every night before bed which helps a lot of gut health and basically serves as a probiotic is my understanding. I have definitely heard it can be gnarly.
I probably won't do another long fast like that for awhile. It's really challenging with kids since I cook dinner every night and frankly I think it sets a bad example for them from a "food is bad" perspective.
I am after the autophagy and undoing years of damage I've done to my life with late night binge snacking while working.
