The drastic rise in the prevalence of obesity has lead to an exponential increase in insulin resistance. Insulin resistance is a metabolic disorder that has been linked to the development of many chronic diseases such as type two diabetes. The purpose of conducting this study was to examine how exercise and/or nutrition can effect the reversal of insulin resistance. Through the compilation of peer reviewed journals, data on the reversal of insulin resistance through diet and/or exercise was gathered. It was found that the development of insulin resistance and the reversal of insulin resistance can be facilitated through both diet and exercise. Exercise was shown to increase non-insulin mediated glucose transport by increasing GLUT4 receptor expression as well as increasing intramuscular triglyceride metabolism. In contrast, nutrition was shown to have a more prominent effect on weight loss and decreasing internal inflammation. A combination of the two in conjunction was shown to have the most prominent results. Obesity is growing at epidemic proportions in developed nations. Over 1.4 billion adults are currently considered to be overweight or obese (Haskell, 2007). Individuals in developed nations average daily caloric consumption has increased by 200kcal while their energy expenditure has decreased by 800kcal. On average caloric consumption is in excess compared to energy expenditure. Individuals in developed nations have been progressively making a switch to a more
