Asking how he’s achieved such a huge transformation, the 55-year-old said: “I’m on a high protein diet with the good people at Muscle Food so eating an awful lot of lean meat and much as I love chips and other carbs, I am having quite a bit less than I used to.
“I’m not feeling that hungry so you eat less so you lose weight so you’re not as hungry.
“I’m not a drinker but sugar has always been my downfall. A good friend of mine who had the gastric band said it won’t do any good for me as I get all my calories by sugar, and it’s too easy to digest.

According to Healthline, replacing carbs and fat with protein can help slimmers to reduce the hunger hormone and boost several satiety hormones.
The website said: “This leaders to a major reduction in hunger and is the main reason protein helps you lose weight. It can make you eat fewer calories automatically.”
Cutting down on sugar is also a huge help when it comes to shedding the pounds.
This equates to just 30g a day for anyone over the age of 11. For comparison, a can of 330ml Coca Cola contains a staggering 35g of sugar which is around nine teaspoons.
Regularly indulging in foods high in added sugars can cause you to gain excess body fat very quickly which is often very hard to lose, even with exercising.
