Nutrition data and methodology
This page uses USDA SR Legacy FoodData Central record 170093, Potatoes, baked, flesh and skin, without salt: 93 kcal, 2.5 g protein, 21.15 g total carbohydrate, 0.13 g fat and 2.2 g fiber per 100 g. Its medium 173 g serving matches the USDA-derived University Hospitals table, which reports 160.89 kcal for that cooked state.
The Norwegian baked-potato record was considered first, but its 82% edible-part allowance does not explicitly resolve skin inclusion. The USDA flesh-and-skin record therefore better matches this page. All portions use its per-100-g values multiplied by cooked edible grams divided by 100; calories round to whole kcal. The 200 g and 300 g rows are portion examples, not average sizes.
