The Foundational Principles of Phase 1
Phase 1 is a 14-day restrictive period aimed at stabilizing blood sugar, managing insulin response, and reducing cravings for refined carbohydrates by emphasizing lean protein, high-fiber vegetables, healthy fats, and some low-fat dairy. These food choices help promote fullness and curb overeating. During this phase, you will have three meals, two snacks, and a dessert daily, using specific approved foods.
Lean Protein Sources
Protein is key for blood sugar stability and satiety in Phase 1, with a variety of options available. Choices include skinless poultry, all types of fish and shellfish, lean cuts of beef and pork, eggs, soy products, and lean lunch meats.
Approved Non-Starchy Vegetables
Non-starchy vegetables provide fiber and nutrients, and can be eaten generously. Options include leafy greens, cruciferous vegetables like broccoli and cauliflower, asparagus, celery, cucumbers, bell peppers, mushrooms, onions, radishes, and zucchini.
Healthy Fats for Flavor and Fullness
Healthy fats are important for energy and preventing hunger. Approved fats include olive, canola, and avocado oils. Nuts and seeds like almonds, pecans, and walnuts are allowed in moderation, as are avocado (about two-thirds per day) and olives (20-30 per day).
Low-Fat Dairy and Legumes
Certain low-fat dairy and limited legumes are permitted. Low-fat options include milk, plain or Greek yogurt, kefir, cottage cheese, and hard cheeses. Small servings (1/3 to 1/2 cup cooked) of black beans, garbanzo beans, and lentils are also allowed.
Foods to Strictly Avoid in Phase 1
Phase 1 requires the strict avoidance of certain foods to reset your body and reduce cravings. This includes all fruits and fruit juices, grains and starches (bread, pasta, rice, etc.), starchy vegetables (potatoes, corn, peas, carrots, beets), sugary foods, and alcohol. Fatty meats, butter, and coconut oil are also avoided in favor of healthy unsaturated fats.

This structure provides three meals and two snacks daily, plus dessert.
How to Succeed in Phase 1
Success in Phase 1 is aided by planning, meal prepping, and having approved snacks available. Staying well-hydrated with water (at least 64 ounces daily) and engaging in regular exercise are also recommended.
