liver, muscle, and adipose tissue, to respond to physiologic
doses of insulin, and failure of pancreatic -cells to prop-

levels. Obesity is a significant risk factor for the develop-

extremely lean, lipoatrophic models have revealed a similar
predisposition to developing diabetes. Although it may
seem paradoxical that both increased adiposity and se-
