Customarily, carbohydrates should be incorporated in the diet plan of athletes so as to avert the exhaustion of glycogen stores. An alternative has been used by the athletes for the prevention of glycogen stores is the inclusion of in demand and well liked ketogenic diet. Ketogenic diet has shown to ameliorate the physical performance of athletes performing low intensity physical performances. However, contradictory results of ketogenic diet have represented that athletes performing high intensity or ultra-endurance exercises for longer duration is accountable for impairing their operational capability which in turn weakens the physical performance as the elevated levels of fatty acids cannot be remunerated for lessened muscle glycogen reserves. Besides the enfeeble physical performance, ketogenic diet deleteriously affects the metabolic health of athletes by causing the issue of dyslipidaemia, ketoacidosis, renal stones, renal disease, etc. Redirecting from high intensity to low intensity physical activities and overcoming the metabolic disturbances aid the athletes in achieving appreciable and favourable results. Hence, it is eminent to emphasize on the quality and quantity of macronutrients of ketogenic diet while planning the diet for athletes. This type of physical and dietary modification can aid in achieving appreciable and progressive results by enhancing the physical performance of athletes and reducing the metabolic disruptions.
