Kate Middleton is known for her suave appearance, slim body and glowing skin. The latest report reveals the Duchess of Cambridge's beauty secret that gives her that healthy glow and helps her keep her body toned and in good shape.

Independent.ie is reporting Kate Middleton loves fresh fruit and vegetable juices, and her assistant in extracting the nutrients from raw food is Nutribullet. The report notes Nutribullet is a "mini-rocket-like 'superfood extractor'" that helps her make healthy drinks and smoothies easily. It is described as a "cross between a blender and a juicer." The kitchen appliance has the ability to extract nutrients from spinach to Brazil nuts to most about everything else.

In July, Express UK reported that "drinking natural fresh fruit and vegetable juices" allowed Kate Middleton to slim down before her much talked about royal wedding in 2011. She has been using the machine since that time. According to the report, the Duchess was able to drop over "half a stone in four weeks." At the time, her dress size was 6.

However, New York Post claimed Kate Middleton and her mother did a Dukan Diet to prepare for the big day. The routine follows a protein-based diet plan that includes protein in its pure form, vegetables and only lean meat. The diet regime was designed by French doctor Pierre Dukan. The diet gained popularity in 2000 and is followed by several celebrities. It is said that if strictly followed, the diet plan has the capability of giving "dramatic results."

Kate Middleton also created quite a stir when she made her first public appearance after Prince George's birth in 2013. According to the reports swirling around, the Duchess of Cambridge regained her pre-pregnancy body within five weeks of her first delivery.

Speaking to Now Magazine, celebrity fitness expert Nicki Waterman revealed she may "have gone back to eating healthily and being active as a hands-on mum." Furthermore, it was reported the Duchess may have followed a routine that included prenatal yoga and "frequent country walks near her family home in Bucklebury."
