Grape skin extract versus placebo in patients with metabolic syndrome and insulin resistance. A double blind, randomized, multicenter study.

In adults with metabolic syndrome, is grape skin extract combined with diet/exercise orientation effective in insulin resistance (measured using the homeostasis model assessment of insulin resistance [HOMA-IR] index), as compared to placebo plus diet/exercise orientation?

Brief summary

In adults with metabolic syndrome the study will compare the efficacy of a grape skin extract combined with non-pharmacological treatment (diet/exercise orientation) in insulin resistance (measured using the homeostasis model assessment of insulin resistance [HOMA-IR] index), as compared to placebo plus non-pharmacological treatment (diet/exercise orientation). The hypothesis will consider the superiority of the grape skin extract therapy.

Interventions

Two arms: 1)grape skin extract 500 micrograms, three times a day, for 24 weeks; tablet 2)placebo (microcellulose) 500 micrograms, three times a day, for 24 weeks; tablet Both arms will have non-pharmacological treatment (specialised diet taken daily for 24 weeks/exercise orientation: regular light/moderate-intensity physical activity at least 30 minutes daily, 4-7 days/week) according to the First Brazilian Guideline on the Diagnosis and Treatment of The metabolic Syndrome- Brazilian Society
