Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
Boiled potato is 86 kcal per 100 g against 77 raw — the flesh loses a little water to the steam even while sitting in water, so the figure rises slightly. Almost nothing else changes: the fat is still 0.1 g per 100 g. Butter is what usually follows, and a tablespoon of it on a medium potato adds 100 kcal to 144, nearly doubling the plate.
Logging this food
A large boiled potato is 300 g and 258 kcal, a medium 167 g and 144, a small 125 g and 108; half a cup is 78 g and 67. The cooked sizes are smaller than the raw ones for the same potato — the large raw potato was 369 g — so pick the row that matches when you weighed, not the one that matches how it was cooked.
Swaps and alternatives
Boiled sweet potato is 76 kcal per 100 g, the lightest in this family. A baked potato with skin is 93. All four sit within 17 kcal per 100 g of one another, so the choice between potato types is nutritional rather than caloric: what matters is boiled against roasted, and butter against none.
