A Kansas State University professor is on a 30 day long diet of entirely snack cakes and fatty foods to prove that some common beliefs about nutrition are untrue.

Mark Haub, professor of human nutrition, teaches an obesity-related, energy balance course that sparked his diet idea.

"The overarching principle is to bring to light some of the issues with obesity, our understanding of health, health outcomes and societal issues on what is good," he said.

Haub wants to show that foods known to ruin diets may not have that effect, and he wants to point out that there is no strong definition of what healthy weight loss is.

He will be recording his results on Facebook throughout the course of his experiment.

His special four-week diet started Aug. 25. It includes products like peanut butter-chocolate bars, chocolate cake rolls, breakfast pizza, donuts and sugared cereal.

Within the first four days of the diet, Haub had lost seven pounds by eating foods high in saturated fats and sugar while maintaining his calorie goal of 1,800 kilocalories a day.

"It's portion controlled. I'm eating foods that are deemed by many to be unhealthy; we will see if they are," he said.

"I'm not doing 'Super Size Me,' where I'm eating until I'm stuffed or overeating until I regurgitate, as Morgan Spurlock did with his documentary," said Haub.

"The purpose is to illustrate metabolic, mental and sociological issues surrounding weight. The principle is simple: eat fewer kilocalories than I expend," he added.

Haub is monitoring his health by measuring his body mass index, body composition, blood pressure, cholesterol and glucose. (ANI)
