Study blames inactivity, not diet, for alarming increase in childhood obesity

According to an article in the New York Post:

American teens have been getting fatter over the past two decades - not because they've been eating more, but because they've been exercising less, a study says.

Researcher Lisa Sutherland of the University of North Carolina at Chapel Hill analyzed federal data on the diet, weight and physical activity of kids 12 to 19. From 1980 to 2000, their calorie intake rose 1 percent and obesity rose 10percent, while physical activity dropped 13 percent.

Those percentages show that teens must have been getting fat primarily because they burned fewer calories.

The article has a small disclaimer that the study was "funded by an unrestricted grant from the National Soft Drink Association". Let that take you where it will . . .
