A Las Vegas man’s effort to lose weight has driven him to a diet of strictly dog food in the New Year.

Mike Konowalski is a nutritional consultant who is hoping to convince others that there is no magic pill that can eliminate fat, and the solution must come from a lifestyle change.

“Anybody who’s choosing the new lifestyle, we have to suffer. There’s no other way around,” he said. “I think the dog food that I’m eating right now is more healthy than what I’ve done in a year.

Konowalski claims to have lost seven pounds in the first three days of his new diet, which consists of Milk Bones and organic canned dog food.
