Abstract The Mediterranean and a low carbohydrate diet are two popular dietary approaches recommended for cardiovascular and metabolic health, respectively. This trial will compare the combined effect of these diets to either approach alone for the treatment of the metabolic syndrome (MetS). Males and females (n=222), 30-75 years, with at least three MetS risk factors will be randomised to one of 3 diets: i) Traditional Mediterranean (∼55% of energy carbohydrate CHO:15% Protein Pro: 30% Fat), ii) Lower Carbohydrate (∼35%CHO:20%Pro:45%Fat), or iii) Lower Carbohydrate Mediterranean (∼35%CHO:20%Pro:45%Fat) diet for 12-weeks. The primary outcome measure is the MetS Severity Z Score (MetS-Z), a composite score of risk factors, sex and ethnicity. MetS-Z will be calculated pre and post intervention using fasted blood samples for plasma triglycerides, HDL-cholesterol and glucose, systolic blood pressure, body weight and waist circumference measures. The findings from this trial will offer new insights into the most effective dietary strategy for managing diabetes and reducing cardiovascular risk in individuals with metabolic syndrome.
