I'm A Celebrity... Get Me Out Of Here! is one of the most challenging shows on television.
It puts your favourite stars through wringer, making them live in survivor-like conditions.
While it is undoubtedly an emotionally-charged experience, their time in the jungle has physical repercussions.
For many celebrities, after consuming mainly rice and beans, they accidentally go through a complete body overhaul resulting in a massive physical transformation.
Before this evening's episode reveals how much the remaining contestants have dropped, we check out the biggest before and after moments from the series!

Actress Kerry Armstrong entered the jungle in peak condition.
But the I'm a Celeb environment helped the 60-year-old achieve a svelter looking figure.
