The Aussie celebrity chef weighed into the debate about Oliver's size, which was ignited a few days ago when Oliver called a journalist a "bitch" after she asked if he had gained weight since his last visit to Australia.
Insisting that he is a big fan of the British chef and food campaigner, Stone countered that Oliver should keep himself in better shape because he is always encouraging healthy eating.
Stone told The Talk: "The interesting part of this for me is that Jamie is a big voice and he preaches, you know his show is called The Food Revolution. So, he's there talking about healthy food and you've got to practise what you preach.
''I love Jamie. I think he's a great guy. I think what he stands for is really important. We've all had different relationships with food - some great, some not so great. But when you've got a place in the TV world of responsibility, you've got to follow through.''
Oliver said during his recent trip to Australia: "I do my best... working in the food business is quite hard when someone is constantly asking you to try things. I eat fresh, I train twice a week. I could definitely do better, but I am trying to do my best, like most people when they hit 30."
