Undoubtedly, you have heard about the ketogenic diet, or “keto.” Keto is frequently billed as a euphoric diet that allows all the fat one wants to eat while also losing all the fat. Well known in the neuro-medicine community as a treatment for intractable epilepsy since the 1920s, its popularity has shot up recently after a few celebrities experienced weight loss on the diet. Instagram currently has 10 million+ tags for #keto. Take a deeper dive with me to separate fact from fiction and pros versus cons of this hot topic!
In the simplest of terms the keto diet is a very low- or no-carbohydrate eating plan that forces the body into a state of ketosis, an altered metabolic state that uses ketone bodies instead of glucose for energy. In general, the keto diet is composed of foods:
Ketogenic Diet Patterns
With keto’s growing popularity, many eating patterns have evolved from the original therapeutic diet of the 1900s. The most restrictive types are the classic ketogenic and the medium chain triglyceride (“MCT”) supplemented ketogenic diet, and slightly less restricted Modified Atkins Diet (“MAD”).
To maintain very high fat intake, keto dieters must incorporate many sources of fat into their diet; most fat is long chain triglycerides found in meat, fish, dairy products, eggs, oil, and organ meats. On the MCT keto diet, MCT oil is incorporated into the diet as a supplement or through foods including palm kernel oil and coconut oil. The MAD approach continues to restrict carbs but liberalizes protein intake, somewhat increasing palatability of and adherence to the diet.
Due to the highly restrictive nature of the diet eliminating most fruits, many vegetables and most grains, adults who choose to follow the keto diet will likely need dietary supplements including but not limited to a multivitamin, mineral and trace element, calcium, magnesium, folate, and vitamin D. Some dieters choose to “cycle” off the diet 1-2 days per week after several weeks or months in ketosis, which may help to maintain adherence and reduce health risk factors.
Expect to see more ketogenic foods, supplements, marketing/sales, social media posts, apps, and cookbooks. Research is catching up with this fad and a few long-term quality studies (>2 years) have been completed. It is an exciting time for research exploring how diet influences short-term and long-term health.
Thinking about ‘going keto’ or embarking on a similar diet change? Ask yourself, “Is this a plan that I can easily follow for the rest of my life and continue to find it enjoyable? Does it inherently provide all of the nutrients needed to thrive? Will it help me maintain or improve my overall health? ” If your answers are mostly no or questionable, there’s a good chance that it is not in your best interest to pursue it at this time.
