Body weight is determined by an interaction between genetic, environmental, and psychosocial factors acting through the physiological mediators of energy intake and expenditure (1). By definition, obesity results from an imbalance between energy intake and energy expenditure and in any individual, excessive caloric intake or low energy expenditure, or both, may explain the development of obesity. A third factor, nutrient partitioning, a term reflecting the propensity to store excess energy as fat rather than lean tissue, may contribute.
