Methodology
Randomized double-blind placebo-controlled trial of 500 mL green tea containing 25, 180 or 279.5 mg catechins at mealtimes for 12 weeks, with abdominal fat area measured by CT
Key Findings
Both low- and high-catechin groups showed significant reductions in visceral and subcutaneous fat areas versus control at 12 weeks.
Conclusions
Green tea enriched with galloylated catechins reduced abdominal fat in moderately obese adults.
Limitations
Single-country population, industry-linked beverage study, effect sizes modest and diet not tightly controlled.
Supplements Studied
Both the low- and high-dose groups exhibited significant reductions in visceral and subcutaneous fat areas compared to the control group at 12 weeks post-intervention.
Outcomes Measured
Both the low- and high-dose groups exhibited significant reductions in visceral and subcutaneous fat areas compared to the control group at 12 weeks post-intervention.
