The prevalence of obesity continues to increase exponentially worldwide. In the United States, where the majority of the adult population is at least overweight, this condition accounts for an economic burden in billions of dollars per year. Despite increased awareness and determined efforts, the epidemic remains uncontrolled and constitutes a global public health problem. Moreover, the current state of knowledge may not include critical aspects of the etiology of obesity.
