The ketogenic diet is a low-carb, high-fat diet that involves avoiding foods like bread, pasta, potatoes, rice, pastries, and other products made with flour or refined sugar. Some fruits like bananas and grapes are also to be avoided. It focuses on increasing the intake of natural healthy fats, such as meat fats, chicken skin, and butter. However, many experts do not recommend this diet due to potential risks for heart health, such as increased cholesterol and triglycerides levels and the possibility of blocked arteries. The Canadian Diabetes Association does not currently recommend this diet for individuals with diabetes. It may be beneficial to consult with a nutritionist to create a personalized meal plan that fits your needs and habits.
