Abstract
Introduction: There is a growing interest in the considerable benefits of grape products
intake, as some studies have indicated that they may improve cardiometabolic risk factors. However,
the widespread impact of grape products on the anthropometric indices is not fully resolved.
Method: The purpose of this systematic review and meta-analysis was to examine the effects of
grape products intake on anthropometric indices in adults. Randomized controlled trials (RCT) examining
the effects of grape products intake on anthropometric indices, published up to December
2021, were identified through PubMed, SCOPUS, and ISI Web of Science databases. 30 studies
with 35 effect sizes, including 1284 participants (708 cases and 576 controls), were included and
analyzed using a random-effects model to calculate weighted mean differences (WMDs) with
95% confidence interval (CI).
Result: The outcomes have revealed grape products intake to significantly decrease body weight
(p = 0.001) and body mass index (p = 0.004) in obese participants, and also, a greater effect was
observed when grape seed extract was used.
Conclusion: Our study suggests that grape products intake may help to decrease body weight in
obese participants. Future large RCTs with longer duration and obese populations are needed to expand
our findings.
