Physiological effects of epigallocatechin-3-gallate (EGCG) on energy expenditure for prospective fat oxidation in humans: A systematic review and meta-analysis
Kapoor MP, Sugita M, Fukuzawa Y
Published in The Journal of Nutritional Biochemistry
Methodology
Systematic review and meta-analysis of 8 randomised controlled trials of EGCG on respiratory quotient, energy expenditure and fat oxidation
Key Findings
EGCG supplementation produced a significant reduction in respiratory quotient versus placebo, indicating a shift toward fat oxidation
Conclusions
Green tea catechins produce a small measurable shift in substrate use rather than large fat loss
Limitations
Few trials, varied doses and durations
Supplements Studied
Green tea catechins (GTCs) are known to improve fat oxidation (FOX) during fasted, rested and exercise conditions
Outcomes Measured
EGCG supplementation provided significant mean difference (MD) when compared with placebo for RQ [MD: -0.02; 95% confidence intervals (95% CI), -0.04 to 0.00
EGCG intake moderately accelerates EE and reduces RQ
