Voigt is going on an all spuds diet for 60 days. During that time he estimates he will eat about 20 spuds a day.
The potato has vitamins and minerals and not a lot of calories, if eat it without the sour cream, bacon bits and melted-cheese sauce.
He won't be taking vitamins, though he's checking with nutrition experts to see whether colored-flesh potatoes have Vitamin A. He will try to stick to Washington spuds – easy enough since the state is the second-leading grower.
But he travels a good bit, so he may have to eat a tuber from Maine or Wisconsin or – perish the thought – Idaho.
The diet will take him to Nov. 29. That is after Thanksgiving. And Voigt admits the holiday will be a temptation minefield.
