In the new book, which was released April 7, Buettner distills the researchers’ findings on what all the Blue Zones share when it comes to their diet. Here’s a taste:
Stop eating when your stomach is 80 percent full to avoid weight gain.
Eat the smallest meal of the day in the late afternoon or evening.
Eat mostly plants, especially beans. And eat meat rarely, in small portions of 3 to 4 ounces. Blue Zoners eat portions this size just five times a month, on average.
Drink alcohol moderately and regularly, i.e. 1-2 glasses a day.
