The keto diet is high in fats and proteins, and low in carbohydrates. It forces the body to burn fat for energy instead of glucose by limiting carb intake and achieving ketosis. Some benefits include reduced hunger, weight loss, and management of medical conditions like epilepsy in children. However, it requires adaptation to the lack of carbs and elimination of certain foods. The best approach is to focus on lean meats, eggs, chicken, nuts and avocados to meet protein and fat needs while limiting carb intake. Careful meal planning and tracking is important for success on the keto diet.
