| Research Abstract |
Exercise has been shown to have a beneficial effect on diet therapy for obese individuals who with to reduce their body fat. From the practical viewpoint, the question often raised is when during the day the exercise should be performed in order to maximize its thermogenic effect. The purpose of this study was to examine the effect of a high carbohydrate diet, compared with a high fat diet, on postprandial energy expenditure during exercise with respect to liver and muscle glycogen contents in rats.
From the results, postprandual energy expenditure during exercise was higher in the rats fed the carbohydrate diet than in those fed the fat diet, which could have been related to the increase of both liver and muscle glycogen storage during exercise in the former. The increased energy expenditure may in part be explained by increased sympathetic activity in rats fed the carbohydrate diet.
