The document discusses the ketogenic diet, which involves eating a high-fat, moderate-protein, and low-carbohydrate diet. This forces the body to burn fat instead of carbohydrates for energy and results in weight loss. The key aspects of the keto diet are that it increases HDL cholesterol, helps manage diabetes, lowers blood pressure, and reduces gum disease. Foods to focus on include meat, fish, eggs, cheese, oils, non-starchy vegetables, and limited nuts and berries. Foods to avoid are grains, refined oils, milk, tropical and high-sugar fruits, juice, processed meat, artificial sweeteners, and alcohol. Sticking to under 20g of car
