Great info on it here ...
... I try to do it more often than not.
This a great video. She mentions anything that isn't water will end your fast/restart your metabolism, I wonder if that includes medications? Your body would have to metabolize the medication to do its job, so it looks like it answers its own question there. I can wait until 9 or 10 AM to eat breakfast, but take medication for the day earlier than that. I'd like to give this way of scheduling a shot, I guess I'll have to do the best I can. I already eat low carb/high fat/keto minded, not strictly right now, but I try to keep my diet close to it.
