Male Sprague-Dawley rats were obtained from Charles River Laboratories. At 23 days of age, rats arrived at the Texas A&M University Kleberg Center animal facilities and then were housed individually in carbonate cages in a temperature- and humidity-controlled room on a 12 h light /12 h dark cycle. After a 5-day period of adaptation to the facilities, during which rats were fed a regular non-purified diet (Harlan Teklad Catalog no. 8604), they were assigned randomly to either a low-fat (LF) or a high-fat (HF) diet (n = 16/diet) (12) as shown in Table 1. Body weight and food intake of rats were recorded on a weekly basis between 4 and 13 wk of age.

Values are means ± SEM, n = 16 rats/diet group.
