The Calorie King: Starchy Varieties
While many assume sweet potatoes are the highest in calories, the truth is more nuanced. Per 100 grams, starchy white potato varieties like the Russet often have a higher raw calorie count than sweet potatoes. Russet potatoes are well-known for their fluffy texture when baked, a direct result of their high starch content. This concentration of complex carbohydrates makes them a strong contender for the highest-calorie potato variety when prepared in a standard, unembellished manner. A medium baked russet potato (about 173g), including the skin, provides approximately 161 calories.
The Decisive Role of Cooking Methods
The biggest influence on a potato's calorie count is not its variety, but how it is cooked. A boiled or baked potato is naturally low in fat and, therefore, calories. However, cooking methods that involve oil or added fats can drastically increase the caloric density.
- Frying: French fries, for example, can have triple the calories of a baked potato because the oil is absorbed during the cooking process. A 100-gram serving of fried potatoes can easily surpass 200 calories.
- Adding Toppings: High-fat toppings like butter, sour cream, cheese, and bacon bits transform a healthy, low-calorie baked potato into a high-calorie meal. The toppings often contribute more calories than the potato itself.
- Processing: Processed potato products like chips or latkes are loaded with additional fats and sodium, making them significantly more calorie-dense than a whole, cooked potato.
Sweet Potatoes vs. White Potatoes: A Calorie Showdown
A common misconception is that sweet potatoes are higher in calories than regular potatoes. However, a head-to-head comparison per 100 grams often reveals the opposite. According to USDA data, a cooked white potato can have about 125 calories per 100g, while a cooked sweet potato has closer to 108 calories. The macronutrient profiles differ as well: sweet potatoes have more sugar and fiber, while white potatoes contain more starch. The higher fiber content in sweet potatoes also contributes to a feeling of fullness, which can aid in weight management.
Purple and Red Potatoes: A Nutritional Glance
Other potato varieties, such as purple and red potatoes, also have distinct nutritional profiles. Red potatoes are generally lower in carbohydrates and calories than russets, and are prized for their nutrient-rich, thin skin. Purple potatoes are notable for their high antioxidant content, but their calorie count can be quite similar to a russet, depending on preparation. For example, a raw purple potato can have a higher calorie count per 100g than other raw potatoes.
Potato Calorie Comparison Table
The table below provides an approximate comparison of calorie counts per 100 grams for different potato types and preparation methods. Note that these are averages and can vary based on size and specific cooking.
| Potato Type | Preparation Method | Calories (per 100g) | Primary Source |
|---|---|---|---|
| Russet Potato | Baked (with skin) | ~90-100 kcal | |
| Sweet Potato | Baked (with skin) | ~90 kcal | |
| Red Potato | Cooked | ~87 kcal | |
| Purple Potato | Cooked | ~80-110 kcal | |
| White Potato | Boiled | ~77 kcal | |
| Any Potato | Fried (Fries) | ~208 kcal | |
| Any Potato | Mashed (with milk/butter) | ~184 kcal |
How to Keep Potato Calories in Check
For those watching their calorie intake, potatoes can still be a healthy and satisfying dietary component. The key is in preparation and portion control.
Maximize Nutrients, Minimize Calories
- Bake, boil, or steam your potatoes instead of frying to avoid adding extra fat and calories.
- Keep the skin on. The potato skin contains a significant amount of fiber and essential nutrients like potassium and Vitamin C.
- Choose healthy toppings. Instead of high-fat sour cream and butter, opt for fresh herbs, Greek yogurt, or a drizzle of olive oil.
- Cool cooked potatoes. Cooling potatoes after cooking can increase their resistant starch content. This type of starch resists digestion, acting like fiber and reducing the overall blood sugar impact.
The Impact of Fiber and Satiety
Potatoes are known to be a very satiating food, meaning they help you feel full and can reduce total calorie intake during a meal. The fiber content, especially when eating the skin, plays a role in this, helping to prevent overeating. This satiating effect, combined with their nutrient density, makes potatoes an excellent choice for a healthy diet, regardless of variety.

Conclusion
While starchy varieties like the Russet tend to have a higher inherent calorie density than sweet or red potatoes, the type of potato you choose is less important than how you cook it. A single baked potato is a low-calorie, nutrient-rich food. However, once you introduce deep-frying or high-fat toppings, the potato can quickly become a high-calorie dish. Therefore, the answer to which potato has the highest calorie count depends on preparation—and often, the highest-calorie version is the one prepared with the most oil and toppings. Focusing on simple cooking methods and healthy additions allows you to enjoy potatoes as part of a balanced diet without excess calories.
What Determines a Potato's Calorie Content?
Several factors determine a potato's calorie content, including its variety, its starch-to-water ratio, and, most importantly, the method of cooking and any added ingredients.
