Reading this book made me a little sick. It wasn't the useful information, like not eating fried meats, sugar, white flour and junk food, eating organic, etc---all stuff you can find online and in many other health food books. What turned my stomach was the narcissism of the author. I'm sure Asprey would decry the fact that 23,000 people die every day of starvation, but this book is all about him. Him and people who are rich enough to jet around doing extreme things so they can live to be 180 and look like they are 25. (And btw if his plan is so good, why is his hairline receding?)
I'm more interested in reading about a plan that will extend the lifespan of, for example, Native peoples who live on Us reservations where the average man dies at age 45. Or, the people of color who are dying from COVID-19 at a rate 2 or 3 times higher than whites in the US. The author makes his living advising rich people how to live longer. Do I really care if Jeff Bezos lives to be 180? In fact, I hope he doesn't. Because the rich enjoy good, healthy lives by sucking the life and labor out of the working masses.
They are also destroying the environment. The corporations bringing all that grass-fed beed into Whole Foods, the companies making collagen for plump middle class skin---they are responsible for burning down the Brazilian rainforest to create pastures for grass fed beef. All that organic coffee is grown on land where Indigenous people used to grow food. Ditto palm oil
A good nutritional plan for the world has to include giving the land back to the people so they can grow their own food. If you are not sure how it came to be that the 1% owns almost everything and billions of people are hungry, read "Capital" by Karl Marx, or "Empire of Cotton" by Sven Beckert, or "Coffeeland" by Augustine Sedgewick. Restoration of indigenous crops and animals has to include thingking in terms of "we" instead of "I." The men responsible for the slaughter of 50 million buffalo in the 19th century (yes, organic, grass-fed, paleo) consciously set out to destroy the Native idea of "we." That is the missing ingredient in this self-centered book.
