Kyle admitted to reaching his "fattest" weight on his 2DayFM morning show, gaining a whopping 26.5 kilograms in less than six months. He now weighs a dangerous 134.5 kilos.
Jackie Oresponded to her co-host's body transformation with trademark sensitivity, posting photoshopped images of Kyle's face on obese bodies on the duo's official website.
"I don't think [the image] is my fate," he said. "It's just been winter. I've been hibernating." In a mysterious burrow of fast food!
According to The Daily Telegraph, Kyle eats a "half a loaf of bread" for breakfast with "milkshakes every day". The Australia's Got Talent judge reportedly sold his Lamborghini because he could no longer fit inside.
"I'd suggest a thorough medical check with a GP and cutting out all soft drink and white bread," Susie added.
However, Kyle's manager Andrew Hawkins has denied that Kyle has a serious health problem.
"Kyle doesn't have diabetes," he said.
"He has a great doctor that he sees regularly for his migraines".
Kyle was hospitalised for a "blood pressure scare" in May, and missed best pal Brian McFadden's wedding due to a migraine. He has had numerous sick days this year from both Australia's Got Talent and his radio show.
Perhaps he could take some inspiration from these celebrity ex-fatties:
