The Four Hour Slow Carb Diet The Slow Carb Diet is based on five rules: avoid white carbohydrates, eat the same few meals over and over again, don't drink calories, don't eat fruit, and take one day off per week to eat anything you want. Under this plan, rice, potatoes, sugar and white flour are out, as are juices, milk and non-diet soft drinks. Ferris does allow one or two glasses of red wine nightly, and the plan allows for a "cheat" day once a week when you can eat anything you want, including otherwise banned foods. On noncheat days, the mainstays of the diet are meats, fish, eggs, legumes and vegetables. **The Slow Carb Diet was presented in Timothy Ferris book, "The 4-Hour Body."
