Catherine Middleton walked down the aisle for her Royal wedding looking much slimmer than she was earlier. This has brought a lot of speculation on the crash diet she had gone through to make herself look perfect in the wedding pictures.

This new diet is called the ‘Dukan Diet’. The diet is a plan that helps one lose weight instantly. You do not keep feeling hungry all throughout with it. It is a high- protein Atkins diet.

The diet has become a huge hit among those wanting to shed off the extra pounds and there have been as any as 4 million copies of it sold so far.

According to health nutritionists and experts, it has been revealed that the diet can be dangerous in the long- term effects it has. It may seem to help one in shedding weight immediately. It may though have serious effects on the body of the person. They might tend to damage their liver with the use of this diet schedule.

"It just doesn't make sense based on the science we know", said Joan Salge Blake, a Clinical Associate Professor at Boston University and Spokeswoman for the American Dietetic Assn. He was of the view that when one eliminates different types of foods in the diet, they tend to deprive themselves of all the nutrition as well.
