But it seems the new host of Top Gear was keen to improve his look further, by shedding a few pounds. And it looks like he’s been VERY successful – as he revealed to fans that he’s lost a whopping one and a half stone in just five weeks recently!

Paddy posted to his Instagram, to share an incredible side-by-side transformation snap – one picture showing his bod five weeks ago, and the other, taken just recently.

The rather saucy shirtless snap shows off the popular TV personality’s hunky muscles, and chiselled back, achieved after all of his hard work.

Paddy confessed that his new slimmed-down figure is down to ‘seven days a week’ of committed, ‘strict dieting’. However, he also revealed that he only actually did three hours of weight training exercise a week to accomplish his hunky new bod!

He wrote: ‘There’s five weeks and a tan between both these pics. I started at 14 stone and finished at 12 stone 4lb. This was down to just three hours a week weight training but 7 days a week of strict dieting.

There’s five weeks and a tan between both these pics. I started at 14 stone and finished at 12 stone 4lb. This was down to just three hours a week weight training but 7 days a week of strict dieting. I was on 4 meals a day all clean eating. I felt great and was getting shredded but personally I thought I looked to small and light for my size, 6ft 1”. I’m back to eating a decent enough diet, for me, now but I’m also enjoying plenty of treats (in moderation). I’m now 13stn 9lb (2nd pic) and happy with my size. Not shredded to death but feel comfortable in my clothes and more importantly I’m not out of breath climbing the stairs!!! #beforeandafter #dowhatsbestforyou #32waist41chest
