title: Resistance to insulin-induced hyperphagia in fat-preferring rats.
abstract: Outbred male Sprague-Dawley rats were screened for their macronutrient (fat, carbohydrate and protein) preference profile and divided into two groups, the low- and high fat-preferring groups each deriving 23% and 72% of its total caloric intake from fat respectively. Subcutaneous administration of bovine insulin (6U/kg) resulted in an increase in total caloric intake in the low, but not the high fat-preferring group. Furthermore, the increased caloric intake in the low fat-preferring group was entirely due to increased carbohydrate consumption. These data suggest a defect in the action of insulin in fat-preferring rats.
