And don't they look just phenomenal!
The Hairy Bikers, Dave Myers and Simon King are known for their love of food and their incredible recipes.
So much so, they have multiple shows based on their foodie adventures.
However, in the past few years, the two of them noticed that their weight had started creeping up, so they made some healthy choices in a bid to get trimmer.
This is what the pair looked like before:
After the two consumed one too many mud pies in Mississippi Adventure, they started Hairy Dieters: How to Love Food and Lose Weight.
Funnily enough, the show was a hit and so was their amazing weightloss.
According to The Guardian, the pair lost a solid 15kgs each in a three-month period. They are now trim and feeling much fitter than ever before. Here's what they look like now.
And it hasn't stopped there, since their weightloss journey, the boys have since gone on to inspire many other fans.
"Still using your diet books, lost 11lbs. Your recipes are so easy to follow and I just want to thank you for producing great tasty food that helps you to lose weight as well!!! Brill," one excited fan wrote on their Instagram.
Meanwhile, they're also on the cusp of releasing a brand new vegetarian-based recipe book, titled The Hairy Bikers Veggie Feasts.
