Slimmed-down Karl Stefanovic shows off his impressive weight loss

He tipped the scales at 105kg last month before embarking on a 10-week weight loss challenge.

So, it’s no surprise Karl Stefanovic has a spring in his step when he showed off his incredible 10kg weight loss on Friday.

The Today show host flaunted his trim physique as he ran errands in Double Bay. 

The 47-year-old opted for a casual and cosy outfit during his stroll, sporting a pair of tracksuit pants and a fitted black T-shirt.

He also had a pair of trendy bright red sneakers on his feet and accessorised with some new age beaded bracelets.

Earlier this year, Karl pledged to lose 10 kilograms in 10 weeks on the Today show, after tipping the scales at 105kg.

Last month, the presenter was well on the way to achieving his goal after a weigh-in revealed that he had lost 5kg in the first five weeks of the challenge.

While his pledge was to lose 10kg, Karl said that he didn’t want to stop there and is hoping to lose a total of 15kg to reach his goal weight of 90kg.

‘I started at 105kg, the heaviest I’ve ever been and it was incredibly embarrassing,’ Karl said as he spoke to obesity expert Dr. Nick Fuller, who is helping him on his fitness journey.

‘I’d like to get down to 90kg at the end of all this. You don’t think that is important but for me, it’s a big psychological thing.’

And, with two more week’s to go in the challenge, it won’t be long until fans discover if Karl has achieved his goal.
