> Taking a hard look at the data above, it appears that the rise in obesity is due in large part to an increase in caloric intake across the board, rather than an increase in carbohydrate in particular.

Ok, but the Calories in/out argument is a silly oversimplification. Pregnant women gain weight because they consume more calories than they expend, but this isn't the most interesting level of causation.

Let's say that one day I drink two cans of Coke in the morning, and measure how I feel for the next few hours. The next day I eat 320 calories worth of chicken breast. To say that an increase in caloric intake can be caused by a change in the kinds of foods consumed is not a contradiction.

The author of this rant either completely misses, or tries to skate around this obvious point, as many do.
