How long hAs it been since you finished your fast and what have you been eating? I felt it appetite came back strong after a long prolonged fast. Was really hard to stop insulin levels spiking and feeling super hungry!
Even tried keto on the last attempt after a Prolonged 3 week fast and it was better but still felt like anything I ate risked spiking insulin levels too high and giving me mad hunger!
I take complications to mean negative health effects. Given that fasting science is in its infancy I really can’t say whether there are long term effects of fasting for so long, things you won’t know about until you are much older. I hope not, but we just don’t know.
For that reason I think, in general, five days or so really should be the maximum for those wanting to improve/maintain health as they age. There’s some data from Russia regarding 21 day fasts, done a maximum of twice from what I recall, but I think there really needs to be more caution.
More isn’t always better.
