The metabolic syndrome has attracted interest because of its relevance to major contemporary chronic diseases associated with inactive lifestyles and the abundance of food, both of which have resulted in a way of life which challenges our genetic makeup. Changing the fuel mix by the introduction of more monounsaturated and polyunsaturated fatty acids, a reduction in saturated fatty acids, an increase in fiber, and the use of low glycemic index slow-release carbohydrate foods may make a difference, as will increasing the amount of vegetable protein and plant foods such as nuts, rich in monounsaturated fatty acids and antioxidant systems. Nevertheless, these supportive measures will be overwhelmed in the absence of calorie restriction combined with adequate energy expenditure. This situation appears to be one where the subsidiary solutions are complex and the central issue is simple.
