ABSTRACT

The prevalence of obesity has increased in the last two decades and it is presently the most common and costly nutritional problem [1]–[4]. In the United States, one-third of the population is affected by obesity, according to the National Health and Nutrition Examination Survey [5]. Despite a known genetic contribution, the increase in obesity prevalence has been largely attributed to lifestyle changes, which means that it is amenable to modification through public health and other interventions [6].
