What is the lowest calorie potato?

4 min read

According to the Irish Food Board, a raw potato contains approximately 77 calories per 100 grams, debunking the myth that all potatoes are inherently fattening. The question of what is the lowest calorie potato involves examining different varieties and, more importantly, how they are prepared.

Quick Summary

This guide reveals the potato variety with the lowest calorie count per 100g, examines how different cooking methods impact nutritional value, and provides a comparative analysis of popular spuds like white, red, and sweet potatoes.

Key Points

  • Boiled White Potato (Cooled): The lowest calorie potato is a plain, boiled white potato, especially when cooled to increase resistant starch.

  • Cooking Method Matters Most: Frying or adding fatty toppings like butter and cheese significantly increases a potato's calorie count, far more than the natural difference between varieties.

  • Resistant Starch Benefits: Cooking and cooling a potato increases its resistant starch, which reduces the digestible calories and boosts fiber content.

  • Sweet vs. White Potato Calories: Raw white potatoes have a slightly lower calorie count per 100g than raw sweet potatoes, though the difference is minimal.

  • Portion Control is Key: For weight management, controlling portion size and choosing healthy cooking methods (baking, boiling, air-frying) is more crucial than the specific potato variety.

  • The Skin is Nutritious: Leaving the skin on, particularly for red and russet potatoes, boosts the fiber and mineral content.

Comparing the Calorie Counts of Common Potato Varieties

When searching for the lowest calorie potato, it's essential to understand that the caloric difference between raw potato varieties is often marginal and less significant than the impact of cooking methods. While many assume sweet potatoes are the healthiest choice, standard white or red potatoes often have a slightly lower calorie count per 100g when raw. The real disparity lies in their nutritional profile, not just the calorie number.

Raw Potato Calorie Breakdown (Per 100g)

  • Traditional White Potato (Raw): Approximately 77 kcal. This makes the common white potato one of the most calorie-efficient options before cooking. The key is in how it's prepared and what is added to it.
  • Red Potato (Raw): Around 89 kcal. While slightly higher than the average white potato, red potatoes are often higher in antioxidants, especially when the skin is left on.
  • Sweet Potato (Raw): Approximately 86 kcal. Despite being perceived as lower-calorie, sweet potatoes have a comparable calorie count to traditional potatoes but boast a different nutritional profile, notably being rich in Vitamin A and C.
  • Russet Potato (Raw): About 134 kcal per small potato (approx. 113g), which puts it at a higher raw calorie density than white or sweet potatoes. However, the large size of Russet potatoes often skews perceptions of their overall calorie count.
  • Carisma Potato: A specialized variety grown by EarthFresh Farms boasts approximately 70 calories per 150-gram serving, making it a notably low-calorie option, though not as widely available as other types.

How Preparation Method Impacts Potato Calories

The way a potato is cooked is the single biggest determinant of its final calorie and fat content. Plainly cooked potatoes like boiling or baking are low in calories and fat, while frying or adding rich, fatty toppings drastically increases the count.

Toppings and Additives: A plain baked potato is far different nutritionally from a "loaded" one. Adding just a tablespoon of butter can add over 100 calories, and piling on cheese, bacon, and sour cream can quickly turn a healthy side dish into a calorie-dense meal.

Frying vs. Baking/Boiling: Frying potatoes, such as in french fries, exposes them to significant amounts of fat, which has more than double the calories per gram of carbohydrates. This is why air-frying or roasting with a minimal amount of oil is a healthier alternative.

The Resistant Starch Trick: An interesting way to lower the usable calories of a potato is to cook it (e.g., boil it) and then cool it completely, preferably overnight in the refrigerator. This process increases the amount of resistant starch, a type of fiber that your body cannot fully digest, effectively lowering the overall calorie contribution. You can then reheat the potato, and the resistant starch will remain.

Low-Calorie Potato Preparation Methods

  • Boiling: As the healthiest method, boiling adds no fat and retains most nutrients. Boiled potatoes are versatile for salads or mashes.
  • Baking: Baking a potato whole preserves the skin, which is rich in fiber. Adding a few herbs and spices instead of butter keeps the calories low.
  • Air-Frying: Provides a crispy texture similar to frying but uses significantly less oil and, therefore, fewer calories.
  • Steaming: A gentle cooking method that, like boiling, adds no fat and keeps the nutrient content high.

Comparison of Caloric Content by Preparation Method

Potato Variety Preparation Calories (Approx. per 100g) Notes
White Potato Boiled, Skin-On ~77-80 kcal Retains nutrients and resistant starch (if cooled)
Sweet Potato Baked ~86-112 kcal High in Vitamin A, naturally sweeter
Red Potato Roasted ~89-100 kcal Rich in antioxidants, good for roasting
Russet Potato Loaded & Baked ~200+ kcal Significantly increases calories with toppings
Any Potato Deep-Fried ~250-300+ kcal High in fat and calories from oil

Conclusion: Which Potato is Best for Your Health Goals?

While the raw calorie difference between potato varieties is small, focusing on preparation methods provides the most control over the final caloric intake. The traditional white potato and red potato often have the lowest calorie counts per 100g in their raw form, but any potato can be part of a healthy, low-calorie diet when baked, boiled, or air-fried with minimal additions. For those specifically seeking a low-calorie diet for weight loss, prioritizing cooking methods that avoid excess fat and practicing portion control are far more impactful than agonizing over a few calories between spud types. Remember that potatoes offer excellent satiety, helping you feel full and potentially reducing overall caloric intake throughout the day compared to less filling foods.

Frequently Asked Questions

Plain boiled white potatoes typically have the lowest calorie count per 100g. When cooked and then cooled, they contain an even lower amount of digestible calories due to an increase in resistant starch.

No, a sweet potato is not inherently lower in calories. On a 100g raw basis, a sweet potato has a comparable or slightly higher calorie count than a regular white potato. The main nutritional differences lie in their vitamin content.

Boiling a potato does not lower its intrinsic calories, but it is one of the healthiest cooking methods because it adds no extra fat. If you boil and then cool the potato, you increase its resistant starch, which effectively reduces the digestible calories.

Yes, a baked potato with the skin on is a low-calorie, healthy option as long as you avoid adding high-calorie toppings like excessive butter, sour cream, cheese, or bacon.

Frying potatoes increases their calories significantly because they absorb the cooking oil. Oil contains more than double the calories per gram compared to carbohydrates, leading to a major calorie increase.

Yes, you can. Potatoes are filling and can aid in weight loss when consumed in moderation and prepared healthily (boiled, baked, or air-fried). The key is to control portion sizes and balance them with protein and fiber.

The healthiest cooking method to minimize calories is to boil the potato in water or bake it in the oven without any added fat. Steaming and air-frying with minimal oil are also excellent low-calorie choices.
