What You'll Eat
Breakfast, lunch, and dinner must adhere to the diet’s strict meal plan. You’ll get between 800 and 1,000 calories per day from foods like toast, grapefruit, canned tuna, saltine crackers, hardboiled eggs, green beans, cauliflower, and even ice cream. You can spice up your dishes with no-calorie seasonings, and drink all the water, tea, black coffee, and diet soda you want—but forget about toppings or beverages that add calories. Between-meal snacking and menu substitutions are also prohibited.
Sound tough? The barebones regimen only lasts three days. After that, you’re free to eat normally for the next four, and then cycle on and off the diet for as long as you wish. While overeating is discouraged, the diet offers no other menu guidance for off days.
