The findings, published in the Journal of Nutritional Biochemistry, showed that mice fed a high-fat diet supplemented with green tea gained about 20 per cent less weight and had lower insulin resistance than mice fed an otherwise identical diet without tea.
Mice fed a diet of two per cent green tea extract had an improved gut health including more beneficial microbes in the intestines and less permeability in the intestinal wall -- a condition called "leaky gut" -- than those that ate a diet without it.
"This study provides evidence that green tea encourages the growth of good gut bacteria, and that leads to a series of benefits that significantly lower the risk of obesity," said lead author Richard Bruno, Professor at the Ohio State University.
Green tea also protected against the movement of endotoxin -- the toxic bacterial component -- out of their guts and into the bloodstream.
"Consuming a little throughout the course of a day with food might be better," Bruno said.
Drinking green tea has also been linked to a lower risk of cancer, heart and liver disease.
