    Long-Term Green Tea Extract Supplementation Does Not Affect Fat Absorption, Resting Energy Expenditure, and Body Composition in Adults Background: Green tea (GT) extract may play a role in body weight regulation. Suggested mechanisms are decreased fat absorption and increased energy expenditure. Objective:We examined whether GT supplementation for 12 wk has beneficial effects on weight control via a reduction in dietary lipid absorption as ...
