The Stillman Diet is a low-carbohydrate, high-protein eating plan that includes unlimited amounts of proteins like seafood, lean poultry and red meat, low-fat cheeses and eggs, according to Diets In Review. The diet does not permit sugars or carbohydrate-rich foods such as vegetables, breads and fruit, the site reports.
Wikipedia notes that fats and oils, dressings, butter and other condiments are not permitted on the diet. Allowed beverages include non-caloric soft drinks, coffee and tea, but only in addition to the required eight glasses of water per day. Dieters are encouraged to eat six small meals per day rather than three larger meals. The plan also instructs dieters to take a multivitamin each day to offset the nutrients lost through the lack of vegetables and fruit.
