Professor of human nutrition at Kansas State University Mark Haub has managed to lose 27 pounds in 10 weeks eating only junk food available at a convenience store. Haub wanted to prove that when it came to dieting calorie counting mattered much more than the nutritional value of food. From the article: "For a class project, Haub limited himself to less than 1,800 calories a day. A man of Haub's pre-dieting size usually consumes about 2,600 calories daily. So he followed a basic principle of weight loss: He consumed significantly fewer calories than he burned."
