Kate Middleton Diet & Weight Loss Secrets: Duchess of Cambridge Baby No.3 Soon, Hints Prince William

Duchess Kate Middleton has given birth to Princess Charlotte only recently, but at the christening of the new royal baby, Kate was seen already sporting a trim figure. Meanwhile, Prince William has hinted in a recent interview that the royal couple may add another child to their growing family. 

When Catherine, the Duchess of Cambridge, walked into the church for Princess Charlotte's christening on July 5, she stunned everyone with her form-fitting white coat from Alexander McQueen, according to Hollywood Life.

Kate gave birth to the royal princess on May 2 this year and it only took a few weeks for her to trim down her weight. According to PEOPLE, Kate has enlisted the help of a London trainer throughout her pregnancy, which explains why the Duchess looked fit while carrying Princess Charlotte in her womb.

The fitness package was exclusively tailored for her. Her trainer regularly monitored her progress by phone, and they meet once a week. As for her diet, Kate is on an organic diet of fruits and vegetables and lean meats.

As for the Duchess' workout routine, Healthy Celeb reports that she regularly runs outdoors for cardio and does rowing at a private gym. For toning, she uses weights and combines squats with lunges or push-ups with step-ups. She also does yoga in between her exercises. The website added that Kate does a bit of swimming and skiing on holidays.

In an interview with NBC's Today, Prince William talked about his new job as a pilot for the East Anglian Air Ambulance. He stated that all his salary for the job will be donated to charity.

Speaking of jobs, the young Duke praised his wife for "doing an amazing job as a mother." He acknowledged that life will soon be more interesting now that he has two children in their family, especially with their first-born George.

"It is more responsibility, looking after two little ones, especially when George is around. He's a little monkey," he said.

When asked if more children will be added to the royal family, Prince William gave an unclear answer.

"We've only just had the second one. You never know what is going to happen in the future," he said with a chuckle.
