A chef from Busy Bees nursery in Rodney Close, Rugby, has transformed his diet from fried foods to healthy meals.
Pete Williams decided to overhaul his diet after taking up his job in March and eat the same dishes as the children.
The 38-year-old, who lives in East Haddon and currently weighs 23 stone 7lbs, had previously worked in pubs and restaurants where he was influenced by the unhealthy lifestyle.
His daily diet revolved around burgers, chips and sweet puddings.
At one point, he weighed around 30 stone.
Pete’s target is to weigh 20 stone by Christmas.
He is raising money for children’s cancer charity Clic Sargent as he sheds the pounds.
Pete said: “When I started working here at Busy Bees, it made me realise just how bad my diet was.
“I was eating fried food all the time and now I am really thinking not just about the healthy meals the children are having each day, but also about myself and what I put into my body.”
He added: “I really hope to raise as much as I can. It is a great cause and is definitely spurring me on. Even after Christmas I am determined to lose even more weight and carry on cooking myself meals from the Busy Bees’ menu.”
