Kate Middleton and Mom Follow Dukan Diet

Several reports claim that Kate Middleton and her mother, Carole Middleton, are both following the Dukan diet. The Daily Mail reported in November that Carole lost four pounds in just four days during the first phase of the diet created by Pierre Dukan. The diet involves four stages, the first of which predominately consists of lean protein.

However, there has been much concern over Kate Middleton's apparent weight loss. Rumor has is that she has been following the same diet plan as her mother although the matter has not been publicly confirmed. "It's a hugely private matter," a press aide told the Associated Press. The 5-foot-10 future Princess was once reported to weight 120 pounds, which is on the low end of what might be considered healthy.

Among a group of well-wishers gathered in Belfast, Northern Ireland, one woman told Kate "not to lose any more weight." Kate replied that it was all part of the wedding plan.

The Dukan diet has received much criticism, and is often compared to the Atkins diet of France. Many argue that the diet promises a quick fix that eventually leads to gaining the weight back, while others argue that it's expensive and bad for the liver.
