Idle = Obese
Sedentary lifestyles, rather than overeating, may be driving the surge in American obesity, Stanford researchers reported in The American Journal of Medicine.
Comparing national health survey results from 1988 to 2010, the researchers found huge increases in both obesity and inactivity, but not in the overall number of calories consumed.
The percentage of women reporting no physical activity jumped from 19 percent to 52 percent during that time period; the percentage of inactive men rose from 11 percent to 43 percent.
The study was led by Uri Ladabaum, MD, professor of gastroenterology.
