Jack, who split from Dani last month, has taken to his socials to show off his weight-loss, after taking part in Protein World's Slender Plan. He wrote, 'Summer come at me 😎 thanks @proteinworld for supporting me in getting in better shape. Couldn’t recommend the slender plan enough. I feel physically and mentally stronger and the journey has only just begun 🥊 🥊 so keep your eyes peeled 🥊🥊 and no I never had a spray tan I had just got back from ibiza'. [sic]
According to reports, Jack lost the weight in just three months, after doctors told him he was 'clinically obese' for his 5ft 11 height.
The popular reality star shredded 11cm from his waist and 42% body fat. Impressive!
The amazing transformation comes just weeks after Jack announced he'd split from Love Island co-star Dani Dyer, despite the pair living together.
He wrote on Instagram at the time, "There is no easy way to say this and it isn't going to be an easy time but me and Dani are not in a relationship anymore.
"We will always care a lot for each other and I mean that from the bottom of my heart and I wish her nothing but happiness.
"We have some amazing memories together and have been through a lot but sometimes things just aren't meant to be and we really did try and make it work but unfortunately didn't and that is life. That's all I have to say, a break up is hard enough as it is for both of us let alone in the public eye so I hope everyone is considerate and understands this. X"
