Clinical Trial Summary

Healthy lifestyle, based on healthy diet and exercise, is a key factor to prevent the most common menopausal disorders and chronic diseases to which women are more exposed during this life stage. Therefore, menopausal women may represent a target for evaluating the effectiveness of nutritional intervention studies based on protective diets against the common metabolic diseases, such as metabolic syndrome, obesity and hepatic steatosis.

Lipidomics aims to study the lipid molecules in a "dynamic" way and allows to define not only structure and functions of a set of lipid species present in an organism, but also the changes that occur during cell metabolism under physiological and pathological conditions in order to understand their role as part of the complex functional balance of a living organism.

Quantitative and qualitative determination of fatty acids profiles in cell membranes allows to follow their molecular changes occurring for intrinsic and extrinsic metabolic causes, such as inflammation, stress, nutrition.

Scientific evidence has shown that, for nutritional studies, the most representative cell is the erythrocyte, which is a biomarker of an individual's general state of health. In fact, the evaluation of the fatty acid composition contained in the membrane of red blood cell, which has an half-life of four months, allows to follow the nutritional status of a subject and to acquire information about his eating habits, with special reference to fat consumption.

The higher intake of omega-3 fatty acids is associated with a decreased inflammatory state which is often altered in patients with metabolic diseases, hepatic steatosis and obesity.

Overweight or obese women in menopause for at least 12 months, aged between 45 and 68 years, will be submitted at baseline to blood samples for lipidomic profile, blood tests, medical examination with blood pressure and anthropometric measurements (weight, height, waist and hip circumferences), indirect calorimetry and bioimpedentiometry. Participants will be randomly assigned to diet with extra virgin olive oil (LoVE DIET) or to diet riched in omega-3 fatty acids (LωVE DIET) for four months. During the treatment period, women enrolled will undergo medical examination and dietary control to assess the adherence to the dietary pattern, collecting anthropometric measurements, indirect calorimetry and bioimpedentiometry after 4 and 16 weeks as well as blood samples after 16 weeks.

The results will be analyzed using appropriate statistical tests. All patients will be made to sign an informed consent.
