Well now, don't blame it all on the gargle. McDonalds and all the other high-fat, deep fried, higly processed fast food crap people ingest in vast quantities are responsible for the epidemic of obesity sweeping not just the US, but much of the western world. And all the attendant problems like diabetes and heart disease.
One major culprit is the high-fructose corn syrup they put in everything from soda to salad dressing. The stuff is deadly. Read the labels. I don't buy anything that lists it as an ingredient.
