James Martin has been looking very well on James Martin's Saturday Morning, and the TV chef has revealed his secret.
James said that eating fish twice a day is one of the game-changing lifestyle adaptions he has made to maintain his trim figure -and he's not even making super complicated fish dishes.

"What could be simpler than pan-frying a little bit of salmon and serving it with some great new potatoes and seasonal veg?" he said.
James also revealed that when he fancies a snack, he reaches for fresh fruit rather than processed treats.
Another small lifestyle change that made a big difference to the chef is cutting out fizzy drinks. He has removed fizzy drinks from his diet altogether and makes sure he consumes the recommended two litres of water a day, resulting in his physique changing without having to go on a diet.

"Losing weight is a balance of everything, it's getting off your arse and doing more and not eating less, but eating a variety of different things.
James explained that staying hydrated had given him other health benefits, including feeling more energised and more switched on mentally.

He said: "Water is the key. As you get older, I realised I don't need to go to the gym, I'm working [in the kitchen] all the time anyway.
"Water keeps your brain healthy and it keeps your skin healthy and it keeps your focused – it's crazy when you give up soft drinks how much more your brain feels alive, it's very weird."
