Evidence-based maximum recommended ketosis duration
I'll start a thread on this if I may.
There are stark warnings about not prolonging a ketosis phase for longer than (insert random number) weeks for fear of (unspecified calamity).
At the same time there are people bragging about having been in ketosis since starting (gym, diet, motherhood etc).
I have no idea whether to deliberately schedule ketosis breaks and if so, how often and for how long.
Anecdotal "I've ketosed for two years without a break and nothing's fallen off yet" don't really help. Is there actually any medical finding, or are all these web doctors just spouting personal opinion?
