I didn't read this too closely but,
"In terms of fast food, Britain 45 percent of Britons agreed with the statement "I like the taste of fast food too much to give it up" ahead of 44 percent for Americans and Canadians at 37 percent.
"
I agree with the statement - I wouldn't give up my take away veggie low fat curry every 3 months. That counts just the same as the guy who eats nothing but burgers, pizza coke, etc saying he wouldn't give them up.
In actual fact everyone is answering the question posed in totally individual ways, so the stats are relatively useless.
The man who eats nothing but burgers, pizza, and cola - who says he could give them up - doesn't count at all in the percentage stats- again showing what rubbish they are!
