We started the year on Arts Wednesday talking about New Year’s resolutions and top of the list for Australians is losing weight. The problem is, we don’t do very well at keeping our resolution. Why do so many of us want to lose weight and why do we all want the silver bullet? Fad diets seem to fit the bill for so many of us. Dietician Dr Jo McMillan makes a welcome return to Arts Wednesday to talk us through the fads.
