Values are means ± SE (n = 6–8). Different letter superscripts within an animal group indicate a significant change between ages (p <0.05). Significant age-associated increases were noted in both animals groups for body weight, absolute food consumption, and fat pad mass (omental and retroperitoneal fat pads).

Indicates values at the respective age are significantly different in OLETF compared with LETO rats (p <0.01).
