His weight has definitely yo-yoed over the years but at the age of 55 Gregg Wallace is now in the shape of his life, after losing more than 25kg.
A vastly improved diet, a regular gym routine and a new-found love of yoga have all helped the MasterChef UK star transform his body from 101kg to 76kg.
And the dad-of-three is clearly proud of his new physique and is happy to show off his muscley upper body and and new six-pack!
Gregg has more than 100,000 followers on Instagram and is now urging them to follow in his footsteps and get fit!
'Fit at 55 ! You can have a new you too!' he wrote on social media and in another post he added, 'If I can do it - so can you.'
The TV host, whose 16th season of MasterChef UK is on LifeStyle, has revealed that he transformed his body because he wants his wife, Anne-Marie, 33, to be 'physically attracted' to him after he became disillusioned with the idea of being the 'older and fatter' partner.
He revealed to The Mirror, "I’ve got more energy and stamina and I’m stronger and leaner than I was at 25."
Gregg also said he received a massive wake up call when doctors told him he had dangerously high cholesterol.
"When I was at my biggest I was having a daily fry-up, fish and chips once per week, takeaway a couple more times and drinking beer nearly every day," he told The Sun.
"I'm a huge fan of curries, chillies and stews and it is still possible to lose weight and eat hearty meals."
He now sees a personal trainer for an hour, five days a week from his home and he has a yoga instructor come to his house too.
Gregg has also been perfecting his healthy recipes for his wife, their one-year-old son, Sid, and his daughter from a previous relationship called Libby, 23.
His fitness journey inspired him to launch his own website showme.fit which helps others achieve a healthier lifestyle.
