This time last year I started the Dukan diet, which is currently garnering headlines as its creator, Dr Pierre Dukan, is in court in Paris suing a rival for libel. Like the low-carb Atkins diet before it, the protein-heavy Dukan diet has come under fire from critics. The current court case is related to an interview with a French magazine in which Dr Jean-Michel Cohen branded the Dukan method a "fantasy" and alleged that it could cause serious health issues. One thing is certain for me - once I started on the diet, I bought the same pair of jeans in progressively smaller sizes.
