Meta-analysis: Green Coffee Bean Extract for Weight Loss
By Heather A. Hausenblas, PhD, and Brianna Huynh
In the past decade, increased research and media attention has been given to the weight loss effects of green coffee bean extract (GCBE). The purpose of our study was to perform a review and meta-analysis of available randomized clinical trials examining the effects of GCBE supplementation on weight loss in both normal weight and overweight/obese individuals. Methods: Electronic and nonelectronic searches were conducted to identify all relevant randomized clinical trials. Reference lists of all retrieved articles were searched, and experts and manufacturers were contacted for unpublished trials. Results: Six randomized trials were included in our review. The meta-analysis revealed a significantly larger weight loss effect for GCBE compared to placebo control (M
ES=0.55). Moderator analysis revealed a large effect size for GCBE with overweight/obese individuals (M
ES=1.00) on weight loss compared to a null effect for normal weight individuals with mild hypertension (M
ES=0.01). There was considerable heterogeneity amongst the studies.

This study seeks to answer these most practical questions.
