How this fits a day of eating
A medium baked potato (173g) is about 161 calories, around 8% of a 2,000 calorie day, with more potassium than a banana. Plain potatoes are among the most filling foods per calorie, which is why the potato itself is rarely what pushes a meal over budget.
Toppings and cooking fat decide the calories. The same 100g of potato is about 93 calories baked but well over 250 as restaurant fries, and a tablespoon of sour cream adds around 25.
Common questions
How many calories are in a baked potato?
A medium potato baked with its skin weighs about 173g and contains roughly 161 calories, 37g of carbohydrate, 4g of protein and 4g of fibre. A large baked potato of about 299g is around 278 calories. Butter, cheese and sour cream are not included, so log those toppings separately.
Are potatoes fattening?
Plain potatoes are not especially high in calories, at about 93 per 100g baked, and they contain almost no fat. In satiety research, boiled potatoes ranked as one of the most filling foods per calorie. Calories rise sharply when potatoes are fried or loaded with butter, cheese or cream.
Does eating the potato skin add nutrients?
Yes. The skin contains a meaningful share of the potato's fibre, along with some of its potassium and B vitamins. Eating a baked potato with its skin adds very few calories, so keeping it on is an easy way to make the same portion slightly more filling and nutritious.
