Abstract
BACKGROUND: Reports have shown that visceral adipose tissue (VAT) is more closely linked to cardiovascular risk factors (CRFs) than subcutaneous adipose tissue (SAT). We aimed to elucidate preferential abdominal fat loss and the correlations between abdominal fat reductions and changes in CRFs achieved with a moderate low-carbohydrate diet (LCD) in patients with type 2 diabetes (T2DM). PATIENTS AND METHODS: Fifty-two outpatients (28 men and 24 women, mean age± SD: 60.0 ± 10.5 years) with hemoglobin A(1c) (HbA(lc)) levels ≥ 6.5% were on an LCD for 6 months. Over a 6-month period, we measured their abdominal fat distribution (using CT) and assessed CRFs, including body mass index (BMI), HbA(1c), fasting blood glucose (FBG), serum insulin, high-densitylipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglyceride levels. RESULTS: The patients showed good compliance with the LCD (1812± 375 kcal/day, % carbohydrate:fat:protein = 35:40:19 for men; 1706 ± 323 kcal/day, % carbohydrate:fat:protein = 41:36:21 for women). Significant decreases (P = 0.05) in BMI and HbA(1c) levels were observed, along with an increase in HDL-C (P = 0.021) in men and a decrease in LDL-C (P = 0.001) inwomen. VAT (-21.6 cm(2), P
