Les Dennis lost three stone after being diagnosed as pre-diabetic.
The 69-year-old TV presenter wants to be fit and healthy for his three children so he cut out the takeaways and dropped the pounds.
Speaking to The Sun newspaper, Les - who has a grown-up son Philip from his first marriage to Lynne Webster, and two children with his third wife Claire Nicholson - explained: "I went to get a check-up with a doctor and they said I was pre-diabetic.
“Luckily I caught it early enough to say, ‘Right, here we go, I have to do something’.
“It has made me take responsibility for my own health. Being an older dad I want to be there for my kids. I want to be here when I am 100.
"They are the most important thing to me. I have to fulfil the responsibility to my kids.”
Les went from 15 stone to 12 stone but he still allows himself the odd treat.
He said: "I was touching just under 15 stone, which I knew was too high — I am 5ft 9in — and I’m now able to get into my old clothes. I changed my diet and rather than eating white bread, I will go for rye or sourdough bread.
“I have cut down on my meat intake, my sugar intake and I follow the Mediterranean diet, which has proven for people to have less diabetes and heart attacks.
"I have cut out white wine and I might have the odd beer. I have the occasional Magnum ice cream.”
And, Les is determined to live life to the fullest after losing friends, including Keith Chegwin who died ]of lung disease in 2017 at the age 60.
He said: “I am still lucky to be around when I think I have lost friends like Keith Chegwin. He was a dear and wonderful guy. He seemed really fit and healthy and things like that are a reminder of how fragile life is.
“I was able to prove that you can reverse pre-diabetes by diet and by exercise and by a strong will. I am happy to still be around.”
