The diet advocates have continuously claimed that by eating less, and
less fatty foods, we could all be slim. Americans listened. According
to the U.S. Department of Agriculture (USDA) Center for Nutrition
Policy and Promotion, total caloric intake, as well as total fat
intake, steadily decreased from 1965 to 1990. During this period,
obesity increased dramatically, Steven Blair, P.E.D., president of the
Cooper Institute noted in a February 2002 Mayo Clinic Proceedings.
"The prevalence of obesity," he concluded, "is unlikely to be due to
increases in daily energy intake."

It appears obvious to me that enough people have lifestyles more
sedentary around and after 1990 than around/before 1965 to explain higher
prevalence in overweightness and obesity now and in the past several
years.
