Answer: Yams are not keto-friendly, as they're very high in carbs.
Though a popular dish at Thanksgiving time, yams are not welcome at the keto table. With over 23 g of net carbs per 100 g serving, this starchy vegetable is as un-keto as they come.
As a general rule, vegetables that grow underground are not keto-friendly. For a keto-friendly yam alternative, consider rutabaga or cauliflower.
