Answer: Potatoes are not keto, as they're too high in carbs.
As much as we love our french fries, potatoes are not keto-friendly. They are very starchy, which means they carry a very high carb content.
A half-cup serving of potatoes contains 11.5 g of net carbs.
As a general rule, most vegetables that grow underground are not keto-friendly. For a keto-friendly potato substitute, consider radishes or cauliflower.
