National Institute of Health offers a summary of a 15-year study by the National Heart, Lung and Blood Institute (NHLBI). The study compared people who ate in fast food restaurants less than once each week to people who frequented the establishments more than twice a week. Those who visited more frequently gained more weight than the other group. They were also more apt to have an increased resistance to insulin, leaving them more susceptible to type 2 diabetes.
