Effect of Melatonin on Oxidative Stress in Obese Adults (MELASTRESSOB)

The present research project aims to evaluate oxidative stress in a cohort of obese adults, subjected to an in-hospital 3-week multidisciplinary body weight reduction program (BWRP) with or without melatonin. Our hypothesis is that melatonin, administered to the obese subject, could be effective in reducing the oxidative stress associated with physical exercise (acute). Specifically, the main objective will be to investigate a difference in the mean levels of some peripheral oxidative stress markers at their peak during an acute exercise session in the two groups (primary endpoint). Secondly, the possible pre-post difference (baseline vs end of treatment) of the peak of each oxidative stress marker between the two groups will be evaluated (secondary endpoint
