To determine potential hormonal mediators of the effect of high-fat diets on the development of insulin resistance, blood leptin, growth hormone (GH), glucose, and insulin responses to a 2 g/kg BW oral glucose challenge were evaluated in weanling female Sprague Dawley rats that were randomly assigned to a high-fat (HF, 39% of calories, 20% fat by weight; n = 10) and moderate-fat (MF, 22% of calories, 10% fat by weight; n = 10) diets. Oral glucose challenges were administered following 5, 7, and 9 wk on the feeding trial. Animals were provided diet in excess of their requirements for growth. Body mass analysis was conducted by dual X-ray absorptiometry (DXA) on the 6th, 8th, and 10th weeks of the trial. HF animals gained more weight after 7 wk, had greater body fat than the MF animals, and similar glucose responses to the oral glucose challenges. HF rats secreted more insulin and leptin compared to MF animals. Lean body mass and serum GH and IGF-I concentrations were not different between the groups. Results of this study demonstrate that leptin but not GH or IGF-I is involved in the development of insulin resistance in growing rats as a result of excess energy intake in the form of dietary fat.
