Kate Middleton is often compared with Princess Diana in international media -- mostly because of their similarly extravagant taste in fashion.

But experts are pointing to another potential connection.

Princess Diana suffered from bulimia and later went on a crusade against the eating disorder. Kate Middleton may also be struggling with eating issues, according to one anorexia expert.

You only need look at the pictures from the [recent] 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 India.tv.

As happens increasingly often in the case of fashion models, the young duchess's appearances risk becoming an advert for anorexia, De Clerq added.

Netizens are also questioning Kate Middleton's weight loss, saying the duchess is too thin.

One blog states, As far as opinions go, some publications have gone so far as to bring in experts to analyze whether Kate's weight loss was healthy, she lost the weight too quickly, she has an eating disorder, and this was all caused by stress. The overall conclusions . . . are that Kate's weight loss was healthy, and that she lost it very slowly, which was healthy as well.

The blogger continued on to say, What is disturbing though, and what the media has glossed over, is that Kate was very thin before losing any weight - flat abs and everything! She looked healthy, had a fabulous figure, and didn't need to lose anything to begin with.

But not everyone is in agreement. Some believe that Kate Middleton's weight loss is being targeted simply because she's in the public eye.

Kate is a public figure and people will criticize her for being too thin or too fat, and that in the public's eye, she'll never be perfect, according to OK Magazine.

Even celebrities are coming out to defend Kate. Selma Blair defended Kate to ET saying that she looked healthy and beautiful. Taraji P Henson said Kate looks fine [and] looks healthy.

Here are photos of the duchess before and after her reported weight loss.
