How this fits a day of eating
A medium baked sweet potato (114g) is about 103 calories, around 5% of a 2,000 calorie day, with nearly 4g of fibre. It is one of the lower-calorie starchy foods by weight and a rich source of vitamin A, which makes it an easy carbohydrate to build a filling meal around.
The potato is rarely the problem; the butter, brown sugar or marshmallow topping is. A tablespoon of butter adds about 100 calories, roughly the same as the sweet potato itself.
Common questions
How many calories are in a baked sweet potato?
A medium sweet potato baked in its skin weighs about 114g and contains roughly 103 calories, 24g of carbohydrate and 4g of fibre. A large one of about 180g comes to around 162 calories. These figures assume nothing is added, so log any butter, oil or sugar as separate items.
Are sweet potatoes healthier than regular potatoes?
They are similar in calories, with baked sweet potato at about 90 per 100g and baked white potato at about 93. Sweet potatoes provide far more vitamin A and slightly more fibre, while white potatoes supply more potassium. Both are nutritious, and the cooking method and toppings matter more than the choice.
Is sweet potato good for weight loss?
Sweet potato suits a weight loss plan well. At about 90 calories per 100g baked, it is filling for its calories thanks to its water and fibre content. Baking, boiling or roasting with a measured amount of oil keeps it lean, while fries and heavily sweetened casseroles add many calories.
How many calories are in 3 medium sweet potatoes?
1 medium sweet potato has about 103 calories, so 2 medium sweet potatoes come to roughly 205 and 3 medium sweet potatoes to 308. The same maths keeps going: 5 medium sweet potatoes are about 513 and ten about 1,026. Use the quantity calculator above for any number up to 20.
