Are sweet potatoes good carbs?
Anecdotally, some individuals that follow low carb or keto macros most of the time find that adding the occasional sweet potato allows them to achieve their personal health goals. Since they are a whole food, sweet potatoes are also considered better sources of carbs than processed foods with added flour or sugar.
However, the purpose and foundation of a ketogenic diet plan is to restrict carbohydrate intake. With that in mind, sweet potato is not a “good” carb for keto because it does not fit the limits that keto places on carbohydrate intake… although it may work on keto in very small amounts.
