Hairy Bikers Si and Dave are popular chefs known for their love of comfort food.
However, the pair have lost a huge amount of weight in recent years.
The friends and chefs revealed how they were warned by a doctor to change their lives.
One of the bikers, Dave Myers, told the Mirror in 2018 how he shrank down from 19 stone to less that 15 stone in a year.
He said: “I am not morbidly obese now. I might feel like a male Adonis if I get to 14st.”
Quitting carbs is how the chef does it, he revealed, adding: “I always lose weight by cutting all the carbs out.”
He chef said: “I just calorie count and knock the booze on the head and then watch the scales to see the weight come off.
The Hairy Bikers diet plan is fairly simple, and still allows them to eat well. /life-style/diets/830565/weight-loss-hairy-bikers
Si has said: “It’s never too late to do something about it, you just need very small incremental steps, such as walking 500 yards more every day.
“It’s not rocket science, it’s not about massive changes. With lots of small changes you develop momentum, you can see the difference.”
How did the Hairy Bikers weight?
Use spices
Si said: “There are very few calories in spice. If you’re clever with herbs and spices you can make fantastic dishes which have less calories.”
Calorie count
Si said: “That’s how Dave and I lost weight, we counted calories, simple as that.”
Tweak your desserts
Si said: “My top tip to make cakes healthier is to use honey and carrots because they’re both sweet.
“Use some skimmed milk, some ripe bananas, some good eggs and spices and you’ve got yourself the base for a great cake.
“Also, you can make fatless sponges, sponges by their very nature have no fat in them when made with egg whites.”
Another chef, Nigella Lawson’s weight loss has impressed fans in recent years.
