Sweet Potato vs Potato: Calories, Nutrition & Which Is Better?
One medium sweet potato (~130g) has about 112 calories, while one medium regular potato (~150g) has about 116 calories β nearly identical. The real differences between them are in micronutrients (sweet potato is far higher in vitamin A) and glycemic response, not calorie count.

Calories: sweet potato vs potato
Sweet potato runs slightly higher per 100g (86 kcal vs 77 kcal for regular potato), but a typical serving flips that: a medium sweet potato is a bit smaller (~130g) than a medium regular potato (~150g), so the real-world calorie counts end up almost identical β about 112 kcal versus 116 kcal.
This is a genuinely close comparison on calories alone. The meaningful differences between these two staples show up in micronutrients and cooking method, not in the base calorie count.
Preparation changes everything: a plain baked or boiled potato of either type stays in the 110β120 kcal range, while fries, hash browns, or a loaded baked potato with butter, cheese and sour cream can push either one past 300β400 kcal easily.
Nutrition comparison
The standout difference is vitamin A: sweet potato is exceptionally rich in beta-carotene, which the body converts to vitamin A, often providing well over 100% of the daily recommended intake in a single medium serving. Regular potato contains very little vitamin A by comparison.
Fiber is slightly higher in sweet potato (3g vs 2.2g per 100g), and both are good sources of potassium, though regular potato often edges ahead here depending on variety. Both provide a similar moderate amount of protein and negligible fat in their plain, unprocessed form.
Glycemic response is where preparation matters most: both potatoes can produce a fast blood sugar rise, especially when mashed or fried, but sweet potato's fiber and lower starch gelatinization in some preparations often give it a comparatively gentler response. Check your carb needs against your goals with the TDEE Calculator.
Which is better for weight loss?
It's a genuine tie on calories β both are moderate-calorie, filling carbohydrate sources when prepared plainly (baked, boiled or roasted without added fat). Fiber content gives sweet potato a very slight edge for fullness.
The bigger weight-loss factor for either food is preparation: a plain baked potato of either type fits easily into a calorie-controlled diet, while fries or loaded versions with butter, cheese and sour cream can turn either into a 400+ kcal side dish. Plan your day with the TDEE Calculator and Meal Planner.
Which is better for muscle gain?
Both work equally well as a carbohydrate base for a muscle-gain diet β moderate calories, decent volume, and easy to pair with a protein source like chicken, fish or eggs. Neither is a meaningful protein source on its own.
Sweet potato's added vitamin A and slightly gentler glycemic profile make it a marginally better everyday choice for general health within a bulking diet, but regular potato works just as well calorie- and carb-wise. Set your protein target with the Protein Calculator and build the week in the Meal Planner.
Which is healthier overall?
Sweet potato has a slight edge overall thanks to its exceptional vitamin A content and marginally higher fiber, both genuine nutritional advantages. Regular potato isn't nutritionally inferior, though β it offers good potassium, vitamin C and fiber of its own, especially when the skin is eaten.
As with most whole-food comparisons, preparation method matters more than which potato you choose: a plain baked or boiled version of either is a healthy carbohydrate source, while fried or heavily topped versions of either lose much of that advantage.
Practical meal examples
Weight-loss plate (~230 kcal): 1 medium sweet potato, baked (~112 kcal) + 4oz grilled chicken breast (~120 kcal) + steamed greens.
Muscle-gain plate (~450 kcal): 2 medium potatoes, roasted (~232 kcal) + 6oz chicken breast (~200 kcal) + olive oil drizzle.
Balanced daily plate (~300 kcal): 1 medium sweet potato (~112 kcal) + 1 medium potato, mashed (~113 kcal) split across two meals with vegetables and lean protein. Build any of these in the Meal Planner.
FAQs: sweet potato vs potato
Which has fewer calories, sweet potato or potato?
They're nearly identical. Per 100g, regular potato is slightly lower (77 kcal vs 86 kcal), but per typical medium serving, sweet potato is marginally lower (~112 kcal vs ~116 kcal) since a medium sweet potato is a bit smaller.
Is sweet potato healthier than regular potato?
Sweet potato has a slight edge thanks to its very high vitamin A content and marginally higher fiber, but regular potato is a solid source of potassium and vitamin C too β both are healthy in their plain forms.
Which has more fiber, sweet potato or potato?
Sweet potato has a bit more β about 3g per 100g versus 2.2g for regular potato.
Can I eat potatoes every day?
Yes, in reasonable portions and prepared simply (baked, boiled, roasted). Daily fried or heavily buttered/loaded potatoes of either type add up quickly in calories.
Is sweet potato better for diabetics than regular potato?
Sweet potato's fiber and preparation-dependent glycemic profile may be gentler for some people, but both potatoes can raise blood sugar meaningfully, especially mashed or fried. People managing diabetes should follow their clinician's specific guidance.
Which is better for gym diets, sweet potato or potato?
Both work equally well as a carbohydrate base around training. Sweet potato's vitamin A content gives it a slight everyday nutritional edge, but regular potato is just as effective for calories and carbs.
