The Pros and Cons of the Keto Diet

Until recently, the ketogenic diet was used exclusively in clinical settings to help reduce seizures in children with epilepsy. But now, people follow it to lose weight, reduce their risk of cancer, lower their cholesterol and manage conditions like diabetes, PCOS (polycystic ovary syndrome) and high blood pressure.

This highly restrictive diet limits starchy vegetables, fruits and even some dairy products. Instead, you eat plenty of fats from meat and fish but may also add some plant-based oils and butter. You avoid most processed foods, sugary sodas and juices, cakes, ice cream and candy. But the keto diet does allow some low-sugar dairy options, like kefir or cottage cheese. You can have a moderate amount of beans and legumes as well as root vegetables like beets, sweet potatoes and carrots.

As a result of cutting out grains, fruits and most dairy, a keto diet could lead to nutrient deficiencies. For example, a person following a keto diet may need to increase their intake of calcium, fiber and vitamin C to maintain adequate levels.

Additionally, the keto diet may cause a loss of essential nutrients such as folate and potassium. If you’re considering a keto diet, consult with a registered dietitian to learn more about the pros and cons. This can help you develop an eating plan that’s appropriate for your health needs and goals. For example, a dietitian can help you determine if this diet is safe for you after bariatric surgery.
