In 2017, she began keeping a food diary, writing down every single thing she ate and drank in a day. Lisa cut out all snacks and only ate a healthy breakfast, lunch and dinner every day. Within a year, she had lost a whopping 12st. At the time, Lisa said: “I decided to lose weight for me. I just did it for me and I was patient. It is down to consumption.” Lisa spoke about her body during her appearance on I’m A Celebrity…Get Me Out Of Here! last year. She told fellow campmate Jack Osbourne she had also cut out alcohol after finding herself drinking three bottles of wine a night. Lisa has really upped her exercise since leaving the jungle in December(Credit: YouTube/ ITV) “I genuinely could not cope when my mum died. I got to the point I couldn’t turn my brain off and the wine suffocated everything,” Lisa admitted. Lisa is now more than 10 years sober. While in the jungle, Lisa confirmed her weight had crept back up. She said in November 2025 that she was a clothes size 16-18. However, Lisa has once again slimmed back down since her IAC stint. In recent weeks, Lisa has told fans on social media how she has been doing swimming and Zumba classes, along with personal training sessions. “I love the gym!” she gushed. The hard work has really paid off, Lisa!
