I read this at the end of 2018, and it propelled me on a path of personal change and continual learning about health and wellness. That space has exploded in recent years, especially in the age of podcasts and social media we’re in, and there’s been more research since – but this book was my trailblazer, and what follows are summary notes I made for myself back then.
Just educating myself a little more about how our bodies – the most important thing we have – function, felt empowering, and it was also surprising, given what I thought I knew already. I still find it somewhat shocking that fasting, something that barely crosses our minds, so simple as to be banal, can be so transformative. The Diabetes Code, by the same author, is similarly excellent.
Obesity as an epidemic is recent, only materializing in the last generation. It began in the 1950’s, as a function of increased life expectancy: the average age of the first heart attack is 66 years, and more people were reaching this age. Cholesterol was thought to cause heart disease, and dietary fat was thought to increase cholesterol, so physicians advocated lower-fat diets, which in turn increased carbohydrate intake. In 1977, a government committee (not a committee of physicians) introduced the Food Pyramid, advocating less fat and more carbohydrates, and the rates of obesity started increasing from that very year. Because refined carbohydrates couldn’t be both good (low in fat) and bad (fattening), it was decided that they weren’t fattening, and instead, excess calories were to blame.
