Most people in a small group of German adults eating only meat said their diet was keto, and they ate a lot of meat every day—plus organ meats, eggs, and some dairy—making it a diet full of animal-based foods.

What we've found so far suggests that people on a carnivore diet tend to follow a ketogenic pattern and eat a lot of animal-based foods like organ meats and eggs. Our current analysis is based on limited evidence, but what we’ve reviewed leans toward this pattern. We analyzed one assertion from a study involving a small group of German adults who ate only meat [1]. In this group, most said they followed a ketogenic diet, meaning they likely kept their carbohydrate intake very low, which is common on carnivore diets since plant-based carbs are avoided. These individuals reported eating large amounts of meat daily, along with organ meats, eggs, and some dairy products. This means their diet was made up almost entirely of animal-based foods, which aligns with both carnivore and ketogenic eating patterns. The evidence we’ve reviewed supports the idea that those on a carnivore diet may also follow a ketogenic approach and prioritize animal-based foods. However, we only looked at one assertion from a small group of people, so our view is still limited. We cannot say how common this is across larger or more diverse populations. Our analysis does not prove this is true for everyone on a carnivore diet—only that it was reported in this specific group. There is not enough evidence at this time to say whether this pattern holds across different ages, cultures, or health conditions. Practical takeaway: If you're considering a carnivore diet, you might end up eating in a way that’s similar to keto, with lots of meat, eggs, and possibly organ meats. But keep in mind, what we know so far comes from very few people, so experiences may vary.
