The research on vegetarian keto diets is limited, but anecdotally speaking, MacDowell says she noticed a handful of positive changes once she started following the diet. “I found that not only did I lose weight very quickly [though in a healthy amount of time], I also noticed things like joint pain was disappearing, my digestion was normalizing, little things that I didn’t at all expect,” MacDowell says.
In addition to a plant-based keto diet being limited in nature, Dr. Axe explains that there’s also a high probability that someone on this diet would struggle to consume enough calories and essential fat-soluble vitamins. This could potentially lead to certain nutrient deficiencies and side effects, like fatigue, as a result. “If you’re at all open to the idea, I would highly recommend that you consider a vegetarian keto diet instead of a vegan keto diet. Include at least some animal products in your diet, such as pastured eggs or fermented cheeses or, even better, wild-caught fish like salmon,” he says. “These goods are great sources of protein, fat, choline and fat-soluble vitamins (like vitamins A and K) that are very difficult to get from plant foods alone.”
