Oprah proudly announces she's now lost over 20kg since joining Weight Watchers

Oprah has hit an impressive milestone in her weight loss journey - the 63-year-old media mogul says she has now lost over 20kg since joining Weight Watchers in 2015.

The TV host is set to proudly show off her smaller waist in the April issue of O, The Oprah Magazine.

"I can honestly tell you I struggle no more," a healthy and happy Oprah says. "I live well while losing weight. It is easier than it's ever been."

Oprah also says she's been able to still eat her favourite foods while on the program.

"I've eaten everything I love - tacos, pasta - I've never felt deprived," she stresses.

Oprah kicked off her journey with Weight Watchers back in August 2015. She revealed in a January 2016 update that she had lost 12kg, and again in December 2016 that she had lost a massive 17kg!
