Catherine Saxby, a member of the Nutrition Society of Australia, suggested in an interview with News.ninemsn.com.au, that the food presented by those on the show is "too rich and heavy".
Ms Saxby said: "I have concerns, and a lot of nutritionists do, that it's sort of presenting it as everyday food that is achievable and that can be eaten every day ... it should be enjoyed now and then, not common fare."
She suggested that such so-called "chefy eating" may be contributing to the increasing rates of obesity in the country.
Ms Saxby then went on to accuse chefs in general of encouraging "indulgent, excessive eating".
She said that food programmes should showcase balanced meals, with plenty of vegetables.
Teenage actress Selena Gomez has blamed her recent hospitalisation on being "malnourished" after she admitted surviving on a junk food diet.
