Lifestyle modification is effective in the prevention of cardiovascular diseases. This study aimed to promote healthy lifestyle behaviours to prevent cardiovascular disease. This study was a quasi-experimental trial with a follow up of two years. The intervention group (n = 102) received intensive individual and group counselling on diet and physical activity. The comparison group (n = 84) was given minimal education through mail and group counselling. Following the intervention, both groups reduced their total fat intake through a replacement in carbohydrate intake. The saturated fat and cholesterol intake was also reduced with a larger magnitude in the intervention group. Fruits and vegetables consumption was increased within the intervention group. The intervention group showed a statistically significant reduction in their mean total cholesterol levels with an intervention effect of -0.38 (95% C.I. = -0.63, -0.14) mmol/l. This study has achieved moderate improvement in dietary intakes as well as the total cholesterol of the participants.
