Foods allowed during the Atkins Diet's induction phase include fish, poultry, shellfish and red meat. Eggs, butter, cheese and a wide variety of vegetables are also part of the induction-phase menu.
The induction phase is the first stage of the Atkins Diet. It is intended to increase the dieter's metabolism by teaching the body to burn fat instead of carbohydrates. This phase of the diet mandates a very low-carbohydrate diet that is high in protein and fat. Dieters follow this phase for a minimum of two weeks, and should remain in this phase until 15 pounds away from goal weight.
What carbohydrates a dieter in the induction phase does consume come from the Atkins Diet's list of foundation vegetables. These vegetables should account for 12 to 15 grams of carbohydrates out of the 20 grams allowable per day in the induction phase. Foundation vegetables include leafy greens, such as arugula and spinach, cruciferous vegetables, such as cauliflower and broccoli, aromatics, such as onions, and vegetables high in healthy oils, such as avocados and olives.
Herbs, spices and condiments are permitted during the induction phase, so long as they are low in carbohydrates and do not contain added sugar. Fresh herbs and spices, such as basil, cilantro, oregano and parsley, are permitted, as are vinegars, Parmesan cheese and sugar-free mayonnaise.
