title: Weight loss increased serum adiponectin but decreased lipid levels in obese subjects whose body mass index was lower than 30 kg/m².
abstract: We hypothesized that weight loss in obese subjects may affect adipokine levels, such as adiponectin and tumor necrosis factor (TNF) α. This study investigated the effects of an 8-week weight-control program on serum adiponectin, TNF-α, and blood lipid level profiles in obese subjects. Twenty obese subjects with a body mass index (BMI) higher than 25 kg/m² were recruited for this weight loss program that used dietetic control and aerobic exercise training. A total of 3 obese men and 11 obese women (mean age, 40.3 ± 10.8 years; BMI, 30.0 ± 3.4 kg/m²) finished the program. Anthropometric and biochemical characteristics in subjects before and after the program were determined. The results showed that subjects' body weight, BMI, waist circumference, hip circumference, diastolic blood pressure, total cholesterol, and low-density lipoprotein cholesterol levels significantly (P < .05) decreased during the program. Further analysis showed a negative correlation between delta adiponectin and delta TNF-α, triacylglycerol, and systolic blood pressure in obese subjects. Subgroup analysis showed that obese subjects whose original BMI was less than 30 kg/m² had significantly increased serum adiponectin levels, and more than 3% weight reduction markedly improved blood lipids and body fat profiles during the program. Our findings suggest that weight reduction through an 8-week weight loss program may have anti-inflammatory and antiatherogenic effects via increased serum adiponectin levels and improvements in blood lipid profiles and systolic blood pressure.
