Introduction Sleep-tracking devices have gained lots of attention over the past few years, and rightfully so. In this post, I expose my own sleep data as collected over a 1-month period by two different sleep trackers - the Oura Ring and the Coros Apex GPS watch.
The Importance of Sleep Matthew Walker’s Best-Selling book “Why We Sleep” seems to come up frequently. I heard the book mentioned in several conversations and podcasts over the past few years, and it piqued my interest in optimizing my own sleep.
Intro I recently ate a ketogenic diet for 4 days, then I fasted through the 3 nights and 2 days that followed. When I resumed eating, 60 hours later, I returned to my “normal” diet. The idea for this weeklong experiment was to push my body into a “therapeutic zone” of ketosis in the fastest way possible, with the least amount of interruption to my day-to-day life. I was successful. My glucose-ketone index (GKI) dropped to ~1 within 24 hours of starting to fast.
