Most dieters focus on cutting excessive calories when it comes to losing weight: no junk food, no sweets, no bread, no real food. But in a new study published in the American Journal of Medicine, researchers say increased caloric intake isn’t the primary reason for obesity; the real problem is lack of exercise.
While increased caloric intake is often blamed for rising rates of obesity, no association between these was found in this study; in contrast, an association was found between the trends over time for lack of physical activity and high BMI numbers. “Our findings do not support the popular notion that the increase of obesity in the United States can be attributed primarily to sustained increase over time in the average daily caloric intake of Americans,” concludes lead investigator Dr. Uri Ladabaum. “Although the overall trends in obesity in the United States are well appreciated and obesity prevalence may be stabilizing, our analyses highlight troublesome trends in younger adults, in women, and in abdominal obesity prevalence, as well as persistent racial/ethnic disparities.”
Uh oh. I guess it’s time to buy that gym membership. And some running shoes.
