My guess as to why the potato diet works is the glycoalkoloids inside potatoes, since potatoes are nightshades. Potatoes contain some of the strongest glycoalkoloids out of the nightshades. By eating only potatoes, you give yourself non-standard amount of glycoalkoloid than most humans get. Glycoalkoloids take more than 24 hours to eliminate in the human body, so there is a build up effect. Another infamous glycoalkoloid is nicotine from the tobacco nightshade. Nicotine is a stimulant that decreases hunger. Stimulants also increase body temperature, which is something that happens on this diet too. Nicotine is also a depressant, which is why your probably still able to sleep on this diet. It's also one reason why smokers tend to be skinnier than the normal population.
