Eligibility
Key inclusion criteria
* Obesity was defined as a waist circumference >100 cm, waist:hip ratio >0.97 and BMI >29 kg/m2.
* Subjects were selected for having insulin-resistance, defined as a homostasis model assessment (HOMA) score (21) >5.1 (i.e. one SD above the mean for a reference population of 22 lean, normolipidemic healthy males of similar age).
* All subjects had plasma triglyceride >1.2 mmol/L and cholesterol >5.2 mmol/L at screening while consuming ad libitum, weight-maintaining diets

Summary
Brief summary
Visceral obesity is strongly associated with dyslipidaemia (hypertriglyceridaemia, low HDL-cholesterol and mildly elevated LDL-cholesterol) and insulin resistance, key characteristics of metabolic syndrome (MetS). Recent evidence has clearly established that the risk of CVD is increased in subjects with the MetS. The precise reason for this remains unclear, but appears to be closely related with dyslipidaemia. Effective management of dyslipidaemia is important to reduce the risk of CVD in these subjects. Hypothesis: Inhibition of hepatic cholesterol synthesis by statins and triglyceride synthesis by fish oils improve lipoprotein metabolism in visceral obese men.
