Martin Clunes, 60, will present Martin Clunes: Islands of the Pacific tonight at 9pm on ITV. While watching the new show, which follows Martin as he explores the islands of the largest ocean in the world, viewers will be reminded of the actors recent weight loss transformation.
In a recent interview, Martin unveiled he managed to lose a whopping three stone in just months.
This was thanks to the 5:2 diet.
The actor told Mail Online: I was fat and while I was getting heavy, I had tired knees and stuff.
So, I thought Id try that diet and the weight came off.

Unlike many other diets, dieters do not need to eat or avoid certain foods the 5:2 diet is about when you eat, rather than what you eat.
However, when speaking to Mail Online, Martin added that he now follows another diet to maintain the ideal weight he reached when on the 5:2 diet.
He said: Now I do 6:1 and that seems to work fine.
I eat anything I want on the other days.
DON'T MISS:
Its easy and seems to keep the weight off me.
The 6:1 diet is the same as the 5:2 but there is just one day of fasting.
The experts behind the health and fitness app Lifesum have recommended which foods slimmers should eat while following this diet.
On normal days, these foods include grains, legumes, vegetables, root vegetables, berries, oils, seeds, dairy products, eggs, and fish.
Meanwhile, on fasting days, it is recommended that slimmers eat green vegetables, eggs, white fish, and low-fat dairy products, such as low-fat yoghurt.
As well as focusing more on his diet, Martin credited doing regular exercise on his farm for his weight loss.
The 60-year-old said: I have a couple of big horses and ride them.
Im very healthy. This is a difficult age, obviously, but Im doing fine Im not on any medication.
He added: The only bad thing about being a farmer is that I stink.
