In the landmark study, "A Satiety Index of Common Foods," in which dozens of foods were put to the test, boiled potatoes were found to be the most satiating food. Two hundred and forty calories of boiled potatoes were found to be more satisfying in terms of quelling hunger than the same number of calories of any other food tested. No other food even came close.

So, an all-potato diet would probably take the gold — the Yukon gold — for the most bland, monotonous, and satiating diet.

Boiled potatoes beat out rice and pasta in terms of a satiating side dish, cutting as much as about 200 calories of intake off a meal. Compared to boiled and mashed potatoes, french fries or even baked ones, do not appear to have the same satiating impact.
