Sweet potato calories: baked, boiled, mashed and fries
A sweet potato is a naturally filling, fiber-rich root vegetable. On its own it stays fairly light — most of its calories come from gentle carbs, so the number moves mainly with how big your portion is, how it's cooked, and any oil, butter or sweet topping you add.
