Question: how many calories in a loaded baked potato?
Answer: It's also a healthy source of vitamins and minerals. Size matters. A small baked potato (about 2 inches in diameter) has about 130 calories while a large baked potato (up to 4 inches in diameter) can have about 275 calories. Toppings such as butter, sour cream, and cheese will add more (sometimes a lot more) calories.
