Former TOWIE star Lucy Mecklenburgh has shared pics showing the dramatic effect Celebrity Island had on her body.
The reality star revealed she lost five inches from her waist and almost two stone during her time on the island.
Lucy, 26, has shared before and after shots to show her fans exactly what not eating for over a week did to her body.

The brunette beauty posed in her underwear to show her followers the full effect.
She wrote: “My poor little body!!!! Soooooo emotional watching the last ep of #celebrityisland .. I can’t believe we did it.. I can’t believe I did it 😃 what an experience!
“I will never doubt myself ever again!! Met some incredible people that will be friends for life. So proud of us all!! #celebrityisland#beargrylls #theisland.”
She added: “PS It only took me 3 weeks to put all my weight back on! I ate ALOT HAHAHHA!!!!”
Shocked fans were quick to comment on the post.
One commented: “Oh my god how did you survive?!”
“Wow! That’s actually scary! Glad you’ve put it back on,” another added.
A third said: “This is horrendous! Well done for doing it but never again!”
During Tuesday’s final episode of the show Lucy told viewers exactly how much weight she had lost.
She said: “I’ve gone down to a 23 inch waist.”
Speaking about her weight loss, Lucy told the Mirror: “I was told you should get used to eating less and less but then I was told: ‘No, no, no you need to put on some weight’. So I put on half a stone.
“It was weird because when you’re there you don’t really feel as thin as you are because you don’t have a mirror so you don’t really know how tiny you are and then you get back and you realise.”
Meanwhile her boyfriend former Corrie star Ryan Thomas also showed off his drastic weight loss from the show.
The couple met back on the show back in April and their romance has continued to blossom ever since.
Ryan, 33, also shared before and after pics on his Instagram.
He captioned the post: “The Final episode tonight everyone. The journey we’ve been on is indescribable.
“My before and after is an example of the lack of food, eight days no eating trying to survive with so little energy. I m extremely proud of myself and my fellow islanders.
“Couldn’t have done it without you guys. The reason I love this show so much is because unlike any other there is no winner, it is a matter of survival and not about competing against each other.”
Viewers have watched the islanders put their survival skills to the test as they try and fend for themselves on a Pacific island.
During the show Lucy and Ryan’s relationship continued to grow with them even sharing their first kiss on screen.
The couple, who went public in July, were spotted sharing a smooch on a beach.

Ryan was seen flashing his bum while Lucy walked out of the sea looking incredible in a black bikini before they shared a steamy kiss on the sand.
Now back in the UK the pair recently enjoyed a family day out with Ryan’s eight-year-old daughter Scarlett.
It seems their relationship is definitely starting to get serious.
