From swimming in the buff to having insects for dinner, it’s pretty obvious that hanging out with Bear Grylls is nothing short of intense. 

But have you ever considered what kind of effect such an experience could have on your body?

Appearing on Lorraine this morning, Made in Chelsea’s Ollie Locke revealed that while filming Celebrity Island With Bear Grylls his weight dropped to just under nine stone.

Ollie was one of ten celebrities who were sent to a remote island for the Channel 4 show and – according to the Mail Online – a combination of extreme hunger, intense physical challenges and dehydration allowed the group to leave the island 20 stone lighter than when they arrived.

Reflecting on a picture of his bony upper body, the 28-year-old reality star explained: “It soon creeps up on you that you don't have any food.  The dehydration is so severe.”

“When I left the island I was under nine stone, I was 11.5 when we started,” he revealed.

TOWIE’s Lydia Bright and JLS member Aston Merrygold also took part in the show.

Thankfully the experience was worthwhile as all the celebrities involved donated their fees to Stand Up To Cancer.
