The ketogenic diet is a high-fat, moderate-protein, very low-carb diet that induces ketosis, allowing the body to use ketones as an alternative energy source instead of glucose. The diet promotes weight loss, manages type 2 diabetes, and improves mental focus and physical endurance by emphasizing low-carb vegetables, meats, and healthy fats while avoiding grains, sugars, and most fruits. Involving family in cooking can foster healthier eating habits and develop a preference for nutritious food choices.
