INS and Obesity: Compared to 15 mildly obese (mean BMI: 30.5 ± 2.7 kg/m2) nondiabetic subjects, the morbidly obese subjects were significantly younger, more likely to be female and had significantly higher BMI, waist circumference and levels of insulin, triglyceride and LDL-C, presumably reflecting their greater level of obesity and associated metabolic derangements (Table 1).
