Baked potatoes with butter are relatively high in calories. A medium-sized baked potato weighing 173 g, topped with 1 tbsp. of butter, provides 263 calories.

You could burn off the calories in a medium-sized baked potato with 1 tbsp. of butter by jogging for 27 minutes or in-line skating for 17 minutes.
Although potatoes are virtually fat free, butter is composed almost entirely of fat. Thus, a baked potato with butter is rich in fat; a medium-sized potato with 1 tbsp. of butter has 11.7 g fat, 7 g of it saturated. This amount of saturated fat is nearly half of the American Heart Association's daily suggested limit of 16 g. Consuming too much saturated fat can increase your risk of heart disease.
Baked potatoes are rich in carbohydrates. A 173 g potato with 1 tbsp. of butter provides 36.6 g carbohydrates. Carbohydrates are your body's primary fuel source, so a baked potato with butter might be a good snack to choose before an athletic endeavor.
Butter doesn't contain any dietary fiber, but baked potatoes do. A medium-sized baked potato with 1 tbsp. of butter provides about 4 g of fiber. This nutrient promotes satiety, aids in regulating blood sugar levels and can help support the health of your digestive system.
Both butter and baked potatoes are low in protein. A medium-sized baked potato with 1 tbsp. butter provides 4.4 g of protein. The Institute of Medicine recommends eating .8 g of protein for each kilogram of body weight daily, as protein helps build and maintain your body's tissues. If you weigh 180 lb., this would equate to 65 g.
