Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Catechin gallate is a type of catechin, a polyphenolic compound found in tea (especially green tea) and some other plants. There is some scientific evidence suggesting that catechins, including catechin gallate, may influence fat metabolism, primarily based on animal studies and a limited number of human trials involving green tea extracts. The proposed mechanisms include the enhancement of thermogenesis (the body's production of heat), increased fat oxidation, and modulation of lipid metabolism pathways. However, most studies have focused on mixtures of catechins (such as EGCG and other catechins) rather than catechin gallate alone.

Some human studies have reported small increases in energy expenditure and fat oxidation after supplementation with green tea extracts high in catechins. For example, a meta-analysis published in Obesity Reviews (2011) found that green tea catechins have a modest effect on weight loss and fat metabolism, especially when combined with caffeine. However, the evidence is inconsistent, and the effect sizes are generally small. Importantly, specific studies isolating catechin gallate’s effect are limited, so most claims rely on broader catechin research.

In summary, while there is some scientific interest and preliminary evidence supporting the role of catechins (including catechin gallate) in fat metabolism, the clinical relevance and efficacy for treating "poor" fat metabolism remain uncertain. The overall quality and quantity of evidence specifically for catechin gallate are limited, justifying a moderate evidence rating.
