Exec Chris Voigt of the Washington Potato Commission explains his plans to exist on nothing but potatoes for next 2 months: "In an effort to remind the public about the nutritional value of potatoes, I am going on a diet consisting of ONLY POTATOES, nothing else. No toppings, no chili, no sour cream, no cheese, no gravy, just potatoes and maybe some seasonings or herbs and a little oil for some of the cooking. I will be on this "potato only" diet for 60 days straight, starting October 1st and ending November 29th. I want to show the world that the potato is so healthy, that you could live off them alone if you had to, without any negative impact to your health. And who knows, maybe it will make me healthier by lowering my blood pressure and cholesterol?" More here.

Question: If he succeeds, what do you think will happen to Voigt's health?
