The Made In Chelsea star shows us a photo of himself taken at the end of filming, when he weighed just under 9st...

It sounds like filming for Celebrity Island With Bear Grylls was seriously brutal.

In case you haven’t heard about the upcoming Channel 4 show, we’ll see 10 VIPs try to survive on an uninhabited island.

It’s for Stand Up To Cancer, so it’s a great cause. However, the contestants weren’t feeling quite so great after shooting had finished. Eep.

Made In Chelsea‘s Ollie Locke is one of the stars who signed up for the programme, and he appeared on Lorraine this morning to talk about his experience.

The 28-year-old revealed that his weight plummeted during his time on the island, leaving him at just under 9st.

He said: ‘It soon creeps up on you that you don’t have any food at all. You can’t just go to a fridge and get a snack. We really didn’t eat for a lot of it.

‘The dehydration is so severe too. You get to dangerous levels of dehydration.’

A topless picture of Ollie was then shown, which showed him with protruding ribs and a thinner face.

Looking at the image, he continued: ‘Wow, I mean my body there… When I left the island, that is what I looked like. I weighed just under 9st.’
