AbstractThis paper will discuss the physiology of the regulation of feeding and exercise, especially as it pertains to anorexia nervosa and obesity. The Melanocortin System is responsible for caloric intake and energy metabolism as it regulates neuronal control of long-‐term energy balance. The specific details of all the components of the Melanocortin System are explained, as well as how neural pathways are affected by obesity and anorexia nervosa. The second writing section discusses the Dopaminergic System in the midbrain ventral tegmental area, and its function as a reward system. The dopaminergic system has fascinating implications for the onset and maintenance of anorexia nervosa, as well as how dopamine dysregulation affects individuals with obesity. Lastly, this paper emphasizes the importance of exercise and the health benefits that result from regular aerobic exercise. Exercise is also examined in individuals with anorexia nervosa as a compulsive, excessive behavior and as a necessary behavior for individuals with obesity.
