Green Tea Catechins Slow the Rate of Fat Accumulation Study description: Lab animals were fed a high-fat diet
intended to make them obese. Then their diets were supplemented with
either 0.5% or 1% green tea catechins (EGCg). Body composition, food intake, and
food digestibility were recorded over a 4-week period.
Type of study: Animal
What happened: Adding EGCg to the diet caused a
dose-dependent reduction of body fat accumulation. That is, the more EGCg
consumed, the slower the weight gain, despite a diet designed to ensure obesity.
Food intake was not affected, but the energy content of the feces was slightly
increased by EGCg, indicating a decrease in food digestibility and a somewhat
lessened absorption of calories.
Researchers' conclusion: "Dietary EGCg
attenuated diet-induced body fat accretion in mice."
