‘I’ve always been a bigger guy, because I love fast food and eating out,’ he told TV Week magazine last month. 

‘But I knew I needed to lose some weight. Being on food rations and not having any of the chocolate or cr*p I eat outside was a sure-fire way to do it.’   

It comes after Kieran was given a second chance by Big Brother following his eviction on Monday night. 

After being voted off the show, Kieran was whisked away to a secret ‘white room’ which exclusively containing white furniture and two mysterious red buttons. 

It will be revealed exactly how Kieran can earn his way back into the competition on Tuesday’s episode.
