Something strange going on here.
I’ve lost some weight (33kg) and have transitioned to a keto diet. Listening to 2ketududes on a plane, Brenda Zorn and Dr Fung in particular.
Started fasting - no hunger, slept great, woke at 5 and went to the gym (first time ever).
What the actual f&$k
Brenda has posted a lot on these forums. She runs a monthly fast called the Zornfast, great name, right??? 
You might want to consider joining in Oct.'s Zornfast, 3rd week of the month, start on Thurs. goes to Sun. But a lot of us adjust those starts and stops, it is for the support and fun of it. Nice to chat about fasting with others doing the same.
Fung’s IDM has a FB page that is free, and the IDM team has online payed support and information site too that Brenda and Fung post on regularly along with Megan and Angel Ramos as well.
