Want to get rid of those extra kilos?

Grab a cup of black tea, say scientists who have found that the beverage may promote weight loss by encouraging the growth of metabolism-boosting bacteria.

Researchers at the University of California, Los Angeles (UCLA) found that both black and green tea changed the ratio of intestinal bacteria in mice. They noted that the percentage of bacteria associated with obesity decreased, while bacteria associated with lean body mass increased.

Previous studies show that chemicals in green tea called polyphenols are absorbed and alter the energy metabolism in the liver.

The new study, published in the European Journal of Nutrition, shows that black tea polyphenols, which are too large to be absorbed in the small intestine, stimulate the growth of gut bacterium and the formation of short-chain fatty acids, a type of bacterial metabolites that have been shown to alter energy metabolism in the liver.

The results suggest that both green and black teas are prebiotics, substances that induce the growth of good microorganisms that contribute to a person’s wellbeing, researchers said.

“It was known that green tea polyphenols are more effective and offer more health benefits than black tea polyphenols since green tea chemicals are absorbed into the blood and tissue,” said Susanne Henning, a professor at UCLA. “Black tea, through a specific mechanism through the gut microbiome, may also contribute to good health and weight loss,” Henning said.
