Whenever I'm keto adapted, I can fast for 23 hours out of every day without any effort. I eat once, between 6PM and 7PM. Recently, I've been following the zero carb movement, which advocates only eating animal products (meat, fish, fat, cheese, cream, egg) and drinking water. I'm looking forward to exclusively eat beef and drink water for an entire month.
