By now you probably know about intermittent fasting, which dominated a lot of the diet talk in 2018. While it’s often referred to as a diet, it’s actually more a pattern of eating whereby instead of eating on and off all day, you fast for a period of time (the sweet spot is often said to be 16 hours). It sounds a lot harder than it is. If you eat an early dinner you pretty much end up fasting that amount of time. I’ve written about it before as it’s something I’ve found to be helpful when it comes to curbing over-eating. Until now experts weren’t putting any emphasis on what times of day people should eat and what times of day they should be fasting, but that has all changed with the release of the book, What to Eat When: A Strategic Plan to Improve Your Health and Life Through Food. I highly recommend listening to Dr. Mark Hyman’s podcast where he interviews one of the doctors who wrote the book (it’s how I first heard about it).
The book, a result of years of research, shows that it’s not just what we eat that matters but when. The idea is to eat based on the circadian rhythm, which is the internal clock that controls how we process food. Besides breaking down the science, internist Michael Roizen and preventive medicine specialist Michael Crupain also have chapters broken down into specific scenarios. For example, what should you eat and what should you avoid if you’re going on a first date, when you’re stressed, when you’re bummed, when you’re fatigued… What I appreciate most about this book is that in addition to being easy to read (since you can just beeline for the chapters relevant to you), it’s all based on science.
I’ve read and skimmed through so many diet and nutrition books and this is only the third one I have been consistently recommending. The other two are The F-Factor Diet and The Four Hour Body. I highly recommend check them all out!
