Today show host Karl Stefanovic vows to lose 10kg

Karl Stefanovic may have stacked on the kilos, but he is determined to get back in shape.

The 45-year-old TV host vowed to lose 10kg and follow a balanced diet on the Today show on Monday.

While interviewing obesity expert Dr Nick Fuller about his healthy diet, Karl said: ‘I’ll put you to the test. I need to lose 10 kilos. If I follow your instructions to the letter of the law, how long will it take me to lose 10 kilos?’

Dr Fuller, who claimed that people that follow fad diets such at Atkins and Keto put on weight down the track, told Karl he’d help him lose the weight. 

‘We will get you to lose the 10, but we will do this properly, so I don’t talk to you in five years time and you have stacked the weight back on,’ he said.

‘We don’t want to see photos on social media with you 30 kilos heavier. We want to see you lighter. You have to a role model for your kids,’ Dr Fuller added.

Karl agreed, saying: ‘I’m committing to this and whoever wants to come along for a ride at home can come with us as well.’

In December, Karl joked about his weight after he was photographed at the beach in Byron Bay.

He shared one of the shirtless pap photos – in which he displayed a noticeably fuller figure – and joked that he looked pregnant.

It was just a hilarious way of confirming that his wife, Jasmine Yarbrough, is pregnant and expecting their first child.

‘After a great deal of speculation… the rumours are true,’ he captioned the picture.

The pair, who married in a lavish ceremony in Mexico in December 2018, welcomed their daughter Harper May, on May 1.
