The book has a very conversational tone, and wouldn't intimidate the average person. I read through the first 90 pages and skimmed the rest - which was mostly recipes and workouts. I appreciate that there was an actionable plan attached and that someone who wanted to follow it wouldn't have to go elsewhere for food and exercise ideas.
The whole book was a bit overly simplistic, though. It would only be helpful for someone with cortisol/adrenal trouble, and that's not where I am right now. I recognize that many people in our culture are totally stressed and sleep deprived, but I'm not. I did glean one useful gem about cortisol spikes and the best time to have caffeine.
I was hopeful that this book would address hormonal fluctuations in the lifespan of women rather than our circadian rhythm. So, I guess I misunderstood the cover copy or didn't read it closely enough.
