A very large body of work has shown positive effects of
on a wide range of biological effects that improve health. Most research has focused on
as the predominant polyphenol in
responsible for thermogenic, antioxidant and anticarcinogenic effects. Several reports have linked
to thermogenesis and fat oxidation in humans through inhibition of catechol O-methyltransferase (COMT), the enzyme that breaks down norepinephrine. Other work has hinted at a possible mechanism by which EGCG decreases food intake and thus it is possible EGCG could enhance compliance to a diet program. Italian researchers studied a unique form of EGCG complexed to a phospholipid N-oleyl-ethanolamine (NOE) in order to make it more bioavailable. The preliminary results suggest better adherence to a dietary weight loss program as evidence by fewer drops after 2 months (6%) compared to placebo (27%). In addition feelings of fullness and satiety were significantly increased and feelings of hunger were significantly decreased in the ECGC group as compared to the placebo group. The EGCG group also had a decrease in depressive symptoms, severity of binge eating and a decrease in insulin resistance. These findings indicate that in addition to metabolic benefits, a novel EGCG-phospholipid supplement decreases the desire for food and food intake thus improving compliance with diet.
