Si King and Dave Meyers shot to fame as the TV duo The Hairy Bikers.
Since making their debut on the small screen, the pair fronted an array of TV series, which saw them tour the world and exploring new foods.
However, despite their day job being focused on all things edible, last year, the foodie favourites were spotted cutting trimmer figures.
The pair lost a mammoth seven stone between them – but they insisted their efforts hadn’t seen them take on any drastic lifestyle changes.
Instead, Si, now 51, actually credited a very small and surprising swap as one of his top slimming tricks.
Speaking to GoodtoKnow last year, the chef explained he had decided to ditch more unhealthy choices when it came to making his breakfast.
Si said: “I don’t have butter on my toast anymore, and I know that Dave doesn’t either, it’s mad isn’t it?”
Revealing how he kept his morning routine just as enjoyable, the TV favourite spilled he instead opted for a very different food spread.
“I just have Marmite and I really like it,” he told the publication.
He said: “I was something like 40 per cent fat, my blood sugar was borderline for Type 2 diabetes and my cholesterol and blood pressure were way too high.
“For me it was incremental. I probably put on a stone a decade which I think a lot of people do.
Another chef who drastically slimmed down in the past is Antony Worrall Thompson.
The Saturday Kitchen and Ready Steady Cook stalwart ditched one type of food which helped slim down by more than a stone during his weight loss journey.
Opening up about his trimmer look during an interview with Standard.co.uk back in 2010, the 67-year-old explained he had previously been drinking around 15 cups of sugary tea.
But, to get trim, Antony ditched the sweet treat, and instead began drinking a much healthier alternative: mint tea.
