Tim Ferriss promotes a diet called the “Slow Carb” where participants cut out sugars and carbohydrate heavy foods. Dairy products are also off the table. Instead the focus is on eating three types of foods: meats, greens, and beans. There are some exceptions to the rules like a glass of dry red wine which make the diet more tolerable. Slow carb features a “cheat day” when any food is fair game for 24 hours.
