Hi Dr. Karasu

As for the big cup controversy, I do think that banning advertising aimed at young children would be much, much more effective at reducing obesity:

"A ban on fast food advertisements in the United States could reduce the number of overweight children by as much as 18 percent, according to a new study being published this month in the Journal of Law and Economics. The study also reports that eliminating the tax deductibility associated with television advertising would result in a reduction of childhood obesity, though in smaller numbers."


"University students who watched over four hours or more of TV per day snacked more frequently while watching TV, recognized more TV advertisements and consumed more energy-dense snacks than students who viewed less than one hour of TV per day."
