Many people eat junk food regularly but others avoid it because it is unhealthy. Chefs Bobby Deen and Nikki Dinki make it their mission to introduce lighter versions of unhealthy foods so the guilty pleasures aren't as guilty. The chefs go around the country to visit restaurants, looking for tasty dishes in need of a caloric makeover. When Deen and Dinki find a dish that fits the bill, they issue a challenge to the restaurant's owner. The original item is put into a head-to-head showdown with the healthier version. If people think the healthier dish tastes as good as the original, it goes on the eatery's menu; if it doesn't test as well, the restaurateur wins bragging rights and a cash prize.
