Basically they're the most filling food per calorie. So if you subscribe to the idea that losing weight is mainly about how many calories you consume, a potato heavy diet should be effective.
And an all potato diet, while monomaniacal, even more effective.
Eggs and fish are also very high on the satiety index. If you threw in pretty much any vegetables and spices of your choosing and just stuck to those along with potatoes, even with a cheat day or three you'd have a very healthy diet which I bet most people would lose weight on.
