What a load of rubbish. As anyone from Britain will tell you, we don't have what you could call BBQ summers! I have no doubt that on the odd occasion when the weather allows that too many calories are consumed. The thing is, it's so infrequent that it can't seriously be given as a "major reason" for obesity as stated in this silly article. If they ever invent waterproof charcoal however, then we might have a problem.....
