What are some features of Doug Kaufmann's Phase One Diet?

The Phase One Diet by Doug Kaufmann focuses on reducing levels of harmful fungi and yeast in the body. During Phase One, dieters follow a fairly restrictive meal plan, which focuses on consuming eggs, meats, nuts, fresh vegetables and certain fruits.

Since the Phase One diet is designed to reduce sugar levels in the body, the plan does not allow wheat, processed carbohydrates, fiber-filled fruits or other foods that are high in sugar. Natural sweeteners, such as stevia and stevia plus, are permissible. The plan recommends that dieters follow the Phase One diet for 30 to 60 days before moving on to the less-restrictive Phase Two plan.
