A thin and lean looking Duchess of Cambridge, Catherine or Kate Middleton has caught the attention of anorexia experts while she was away on her first official royal tour abroad to Canada after marriage recently.

According to an Italian anorexia expert, Kate Middleton, who is back from Canada tour along with Prince William, is at risk of contracting anorexia.

You only need look at the pictures from the current visit to Canada to see that she really has lost a lot of weight and that she's bordering on anorexia, Fabiola De Clercq, founder of Italy's Association for the Study and Research of Anorexia told IANS.

De Clercq said the effect is quite visible in all of Kate’s pictures before engagement, around marriage and more recently during the royal couple’s Canadian visit.

Before her marriage in April, Kate went on a low-carbohydrate diet, the Italian expert said, adding that duchess's appearances could become an advert for anorexia.

Check out some of the old and latest pictures of Catherine and you will know why the anorexia expert is concerned.
