burden of disease worldwide" (Haslam and James, 2005, p. 1197). The United States ranks high among the industrialized nations in the prevalent of both conditions (Marks, 2004). Over the last two decades the incidence of obesity has more than doubled (Marks, 2004). In a massive randomized, nationwide telephone survey, the US Centers for Disease Control and Prevention determined that obesity among Americans grew by 5.6 percent in a single year, 2001-2, and that this condition has increased an amazing 74 percent since 1991 (Walgate, 2003). As the incidence of overweight and obesity in the US has increased, so has related health care costs, both directly and indirectly, ass there are a number of chronic, serious conditions that are associated with obesity. For example, in 2001, the estimated cost of diabetes was $122.9 billion and the amount attributable to obesity was $98 billion (Marks, 2004). There is consensus among researchers that obesity results form an energy imbalance in which energy intake exceeds the energy required for daily living, so excess is stored as fat. However, there is considerable disagreement about how this regulation occurs and how "our energy stores generate signals that are compared with targets encoded in the brain," which then, in turn, "drive our food intake levels, activity patterns, and resting and active metabolisms" (Speakman, 2004, p. 2090S). Nevertheless, considerable advances have come about over the course of the last decade in sciences comprehension of this system. Some people become obese because this system, the lipostatic regulation system, does not work properly (Speakman, 2004). This genetic inheritance combines with an environment where food is readily attainable without a high energy investment and obesity develops (Speakman, 2004). Research over the last two decades has also investigated the nature of metabolic syndrome, which is a "constellation" of disorders, specifically ...
