Ketogenic, Paleolithic, and Carnivore Diets

The Ketogenic diet, characterized by 70 to 75% fat, 20 to 25% protein intake, and 5-10 % carbohydrate was originally developed in the 1920’s at the Mayo clinic as a treatment for childhood epilepsy.¹⁶ In recent decades, it has gained popularity as a weight loss strategy. While it can improve blood sugar control and insulin sensitivity, the diet can be challenging to maintain long term and lacks essential nutrients such as fiber and certain minerals.¹⁶

The modern Paleolithic diet is considered the most balanced and sustainable compared to the three, thanks to the inclusion of fruits, vegetables, and lean meats. It emphasizes whole, unprocessed foods that are naturally low in added sugars, which supports metabolic health and reduces inflammation. However, because it excludes grains, legumes, and dairy, it can make it restrictive and potentially more difficult to follow.¹⁶

The Carnivore diet, consisting exclusively of animal products such as meat, eggs, and some dairy, is the most restrictive of the three diets. Studies and anecdotal reports suggest it may reduce autoimmune symptoms and promote rapid weight loss. However, it typically lacks fiber, vitamin C, and other essential micronutrients and its long-term health effects remain unstudied.¹⁶

Food trends are taking a collective shift toward healthier, more sustainable, and technology driven food systems. Key highlights include the growing adaptation to personalized nutrition tailored to individual health needs of our patients. The hope, as healthcare providers, is to encourage our patients to eat real food, read food labels, and incorporate a mindful eating approach that is both healthy and environmentally sustainable.
