| The purpose of this study was to determine the effects of a high protein diet on glucose tolerance in the rat model. Nine Sprague Dawley rats received a high protein diet (65% protein, 35% fat) and eight rats consumed a standard chow diet over the course of eight weeks. An oral glucose tolerance test (OGTT) was performed at the end of the third and the seventh week to measure blood glucose and plasma insulin concentrations. The diet did not effect glucose tolerance in the first OGTT (t = 1.2095, p = .1226) or the second OGTT (t = -.9855, p = .1700) as reflected by the area under the glucose concentration curve. Similarly, the high protein diet did not effect the area under the insulin concentration curve during the first OGTT (t = .5425, p = .2978) or the second OGTT (t = .1709, p = .4333). |
