I really liked this book, I thought it was super interesting. It's marketing pretty, uh, poorly? Like the subtitle makes it seem like a diet / self-help book and it's really not, it's more about science and evolution and other interesting things. The only actual "advice" in this is eat less and exercise more, so if you're hoping for that that's all you need. But it's a really fascinating journey, and it's written super well and has a lot of neat facts in it.
