The premise behind this book was to teach about the body‘s circadian rhythm and how it impacts each part of your day(when you sleep, when/what you eat, etc). A lot of was eye opening and made sense. I‘m just not convinced every person needs the exact same schedule - going to bed by 10:30pm and waking by 6am. However I do love the idea of being consistent and listening to your body. So those are the ideas I‘ll really take away from this
