Zone Diet - Restricted Foods

Ideally, protein sources are low in saturated fats, carbohydrates are low glycemic, and fats are primarily monounsaturated, with a lot of Omega-3 fatty acids.

Conversely, the diet is low in fatty meats, other sources of saturated fat such as butter, most vegetable oil (except for olive oil and similar), grains, added sugars, starchy vegetables, and egg yolks.
