Combined epigallocatechin-3-gallate and resveratrol supplementation for 12 wk increases mitochondrial capacity and fat oxidation, but not insulin sensitivity, in obese humans: a randomized controlled trial

ABSTRACT: The obese, insulin resistant state is characterized by impairments in lipid metabolism. Dietary polyphenols might improve these deteriorations. We have previously shown that 3-days supplementation of combined Epigallocatechin-gallate and Resveratrol (E+R) increased energy expenditure, which was accompanied by improved metabolic flexibility after a high-fat mixed-meal (HFMM) in men. The present study aimed to investigate whether these short-term effects translate into longer-term improvement of insulin sensitivity and lipid metabolism. In this randomized, double-blind study, 42 overweight subjects (21 male, 38±2 yrs, BMI 29.7±0.5 kg/m2, HOMA-IR 2.1±0.2) received either E+R (300 and 80 mg/d, respectively) or placebo (PLA) for 12 weeks (3 months). Before (t0) and after (t3) intervention,
