Influence of Caloric Restriction and Resveratrol in the Sirtuin System in Women and Men Aged 55 to 65 Years

After a washout period of 15 days without medication, men and women will be randomized to the group of calorie restriction or resveratrol so that in 24 individuals (12 women and 12 men) will be given a hypocaloric diet (1000 calories per day) and the remaining 24 individuals (12 women and 12 men), a daily pill of 500mg of resveratrol. In the two moments, after the washout period and before the intervention (baseline) and after 30 days of intervention (final) will evaluate the clinical, laboratory and vascular reactivity of all subjects.
