Study Finds This Tea “Boosts Weight Loss” – and it’s Not Green Tea

We welcome any news that makes us feel less guilty for taking far too many tea breaks throughout the working day, so the latest study on tea has us in the mood to par-tea (sorry) – black tea “boosts weight loss” and heals the gut.

So while green tea is often championed for its health benefits, it turns out that the nation’s favourite, black tea, can give a similar boost to your metabolism.

The study, conducted by researchers at the University of California in Los Angeles set about to determine the difference in health benefits between green and black tea.

Specifically, testing on obese mice, the study concluded that decaffeinated green and black tea polyphenols decrease weight gain and alter microbiome populations and function.

Lead study author Susanne Henning from UCLA said:

“Our new findings suggest that black tea, through a specific mechanism through the gut microbiome, may also contribute to good health and weight loss in humans.”

After four weeks of feeding groups of mice different respective diets, researchers found that those fed a diet that included green tea or black tea extracts lost weight and the growth of “good” gut bacteria, related to lean body mass, was promoted.

While it was proven that both green and black teas can have similar effects on the waistline, the polyphenols in the two varieties are absorbed by the body in different ways; with black tea through your gut bacteria rather than your bloodstream.

As such larger black tea polyphenols remain in the intestine, where they “boost the growth of ‘friendly’ gut bacteria, overall helping to “control liver energy metabolism.”

So here’s to many more tea breaks – you might just want to go easy on the spoonfuls of sugar…
