Very Low Carbohydrate Ketogenic Diets (VLCKD) alter gut microbiota composition by generally decreasing alpha diversity and richness, while selectively increasing beneficial bacteria such as Akkermansia muciniphila and Lactobacillus, which may contribute to metabolic and neurological benefits.

If you start a ketogenic diet, expect your gut bacteria to change. You might see a drop in overall variety, but this often comes with an increase in beneficial bacteria like Akkermansia and Lactobacillus. This shift is linked to the diet's benefits for seizures and metabolism. If you have specific gut issues, monitor your response, as individual results vary.
