Clinical experience with a relatively low carbohydrate, calorie-restricted diet improves insulin sensitivity and associated metabolic abnormalities in overweight, insulin resistant South Asian Indian women.
South Asian Indians are at increased risk for cardiovascular disease associated with insulin resistance and a dyslipidemia characterized by high triglyceride and low high-density lipoprotein cholesterol concentrations. The purpose of this study is to determine the effects of a calorie-restricted, relatively low carbohydrate diet on weight loss, insulin sensitivity, and associated cardiovascular disease risk factors in overweight, insulin resistant, but apparently healthy, South Asian Indian women. Twenty-three, overweight, insulin resistant, apparently healthy, South Asian Indian women were advised on a calorie-restricted diet containing 40 percent carbohydrate for 3 months. Change in weight, insulin sensitivity (quantified by the steady state plasma glucose concentration during the insulin suppression test), and associated cardiovascular disease risk factors were measured. Weight fell from 75.5 to 70.5 kg (p<0.001), associated with significant decreases in diastolic blood pressure, plasma concentrations (mg/dL) of steady state plasma glucose (217 to 176, p<0.001), triglycerides (137 to 101, p = 0.003), and glucose (98 to 92, p = 0.005). A calorie-restricted diet, moderately lower in carbohydrate, can lead to weight loss, decreased insulin resistance, and reduction in several cardiovascular disease risk factors in overweight, insulin resistant, apparently healthy, South Asian Indian women.
