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
Minimum age
20 Years

Key exclusion criteria
- diabetes mellitus, apolipoprotein E2/E2 genotype, macroproteinuria, creatinemia,
hypothyrodism, or abnormal liver enzymes.

- Subjects did not consume fish oil supplements or drank more than 30g alcohol/day.

- None reported a history of CVD, or was taking medication or other agents known to
affect lipid metabolism.

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.
