Daily ingestion of 583 mg of green tea catechins for 12 weeks significantly reduces body fat mass, visceral fat area, and LDL cholesterol in humans with visceral fat-type obesity, independent of changes in usual diet or physical activity.

If you have visceral obesity, drinking a beverage providing ~583 mg of catechins daily (approx. 1.7 cans of the specific high-catechin extract used) for 12 weeks, while maintaining your usual diet and exercise, may help reduce body fat and LDL cholesterol. This is not a magic bullet but a supportive intervention.

GoodSupportsHIGH confidence
The continuous ingestion of a GTE high in catechins led to a reduction in body fat, SBP, and LDL cholesterol, suggesting that the ingestion of such an extract contributes to a decrease in obesity and cardiovascular disease risks.
