It depends what you class as junk food. Some only put the likes of burgers, kebabs and chocolate under this heading, but others have a much longer list which includes 'ready meals', cakes and all types of takeaways.
Yet, there being the guilt factor, after one day of pigging, there may be three days of good behavior. However, I do agree that different folks have different definitions of what is junk food. Anyway, I posted the poll in the hope that folks would endeavor to make improvements in their diets (after this conscience raising).
