The world's in the midst of an obesity crisis, and at least one celebrity chef has been doing something about it -- Jamie Oliver has been trying to get Britain to eat healthier since he launched his School Dinners program in 2005. But not much has changed since then and Oliver is so fed up and disgusted with his fellow Brits, he's threatening to quit if his home nation doesn't start eating healthier.

Says Oliver: "I should and I must and I will go in there and make a difference to these people's lives. I don't know how I am going to do it but if I don't I shall f***ing retire. Simple as that."

I hope he sticks it out -- his cause is certainly a worthy one. Let's get moving, Britain!
