Key differences
Sweet potatoes and white potatoes are both nutritious root vegetables, but sweet potatoes have a significantly higher micronutrient profile. White potatoes have fewer calories and carbs per 100g when baked without toppings. Both are filling, versatile and suitable for most diets.
Beta-carotene: Sweet potatoes are exceptionally rich in beta-carotene (vitamin A precursor) — providing over 100% of daily vitamin A needs per 100g. White potatoes contain negligible beta-carotene.
Glycaemic Index: Baked sweet potato GI: ~70. Baked white potato GI: ~85. Sweet potatoes have a lower glycaemic index, producing a more sustained energy release.
Calories: White potato is slightly lower — 77 kcal vs 86 kcal per 100g raw. The difference is modest: approximately 9 kcal per 100g.
Which should you choose?
🔥 Weight loss
White potato is slightly lower in calories (77 vs 86 kcal/100g) and carbs (17 vs 20g). However, both are low-calorie and highly satiating — one of the highest satiety ratings of any food.
💪 Muscle gain
White potato provides slightly more carbohydrates per calorie — marginally better for post-workout glycogen replenishment. Both are excellent workout carbs.
🥑 Keto
Neither is keto-friendly — both contain significant carbohydrates. Sweet potato: 20g/100g. White potato: 17g/100g.
🌿 Micronutrients
Sweet potato wins clearly — vitamin A (beta-carotene), vitamin C and potassium are all higher. The nutritional density per calorie is superior to white potato.

Frequently asked questions
Sweet potato vs potato — which is healthier?
Sweet potatoes win on micronutrient density — significantly higher in vitamin A (beta-carotene), vitamin C and fibre. White potatoes are slightly lower in calories and have a comparable vitamin C content when cooked.
Which has fewer calories — sweet potato or regular potato?
White potato: 77 kcal/100g raw. Sweet potato: 86 kcal/100g raw. Difference is 9 kcal per 100g — minimal in practice.
Is sweet potato better for weight loss?
Both are effective for weight loss — potatoes consistently rank highest in satiety studies. A 200g baked potato (without toppings) is approximately 154 kcal and highly filling. Sweet potato is similar at approximately 172 kcal.
Do sweet potatoes spike blood sugar more than regular potatoes?
The reverse — sweet potatoes have a lower glycaemic index (~70) than baked white potatoes (~85). Both cause blood sugar rises, but sweet potato's response is more gradual.
Can I eat sweet potato on keto?
No — sweet potato contains 20g carbs per 100g, making it incompatible with strict keto (under 20–30g net carbs per day). Even a small sweet potato (130g) contains approximately 26g carbs.
Are sweet potatoes anti-inflammatory?
Sweet potatoes contain beta-carotene, vitamin C and anthocyanins (in purple varieties) — all with antioxidant properties. They are considered an anti-inflammatory food as part of a varied diet.
Which is better — boiled or baked potato?
Boiled potato then cooled forms resistant starch, which feeds beneficial gut bacteria and has a lower glycaemic response than freshly baked potato. Cooling cooked potatoes before eating significantly reduces their glycaemic impact.
How many carbs in sweet potato vs regular potato?
Raw sweet potato: 20g carbs/100g. Raw white potato: 17g carbs/100g. Cooked values vary by method — boiling reduces carb density through water absorption.
