Effects of the Mediterranean Diet on Cardiovascular Risk Profile in Men and Women

Men are assigned to a 4 weeks isocaloric controlled nutritional intervention based on the Mediterranean diet (MedDiet) in which all foods and drinks are provided. The respective percentages of kcal derived from lipids, carbohydrates, protein and alcohol are respectively of 32%, 48%, 15% and 5%. Habitual energy intake of each participant is established by averaging energy requirements estimated by a validated food-frequency questionnaire (FFQ) and energy needs as determined by the Harris-Benedict formula. Body weight is measured on weekdays and total energy provided is revised if necessary for minimizing body weight fluctuations. This intervention period is preceded by a 4 weeks uncontrolled run-in period based on the Canada's Food Guide.

Women are assigned to the same intervention than men in order to compare men and women metabolic response to the MedDiet.
