Potato has a glycemic index of 78, which is high (low is 55 or under, high is 70 or over). The glycemic load of a 1 potato medium (173 g) serving is 26, which is high.
Glycemic load is the better guide, because it accounts for portion size. A serving of potato has a glycemic load of 26 (high). Eating it with protein, fat or fiber slows absorption further. This is general information, not medical advice; people with diabetes should follow their clinician's guidance.

Nutrition: USDA FoodData Central, SR Legacy, “Potatoes, baked, flesh and skin, without salt” (FDC 170093). Glycemic load = GI × available carbohydrate (carbohydrate minus fiber) per serving ÷ 100. Nutri-Score computed with the 2017 general-food algorithm. NOVA group 1 follows from the NOVA definition: a whole food, only cleaned, dried or cooked.
