Mark Haub of Kansas State University intended to do the junk food diet for just a month for a class. But when he started dropping weight he continued it. Haub ended up losing 27 pounds in two months by eating less than 1,800 calories a day.
Those calories came from snacks including Twinkies, Little Debbie Zebra Cakes and Corn Pops cereal.
Despite his weight loss, Haub says he's not recommending the diet. He says there could be negative health effects if he continued the diet long-term.
