Ketogenic diet for dogs consists of a diet that is low in carbohydrates, moderate protein, and high fat. It uses dietary fat as the primary source of body fuel, where cells use ketones for energy instead of glucose. Coconut oil is an essential addition to the ketogenic diet because it is rich in medium-chain triglycerides (MCTs), which are easily and effectively metabolized by the liver into ketones. Ketogenic diets are beneficial for support of senior dogs, dogs with canine cognitive disorders, seizures, or cancer.
