New Study Says English Breakfast Tea Boosts Metabolism and Supports Weight Loss

A new study claims that drinking black tea may aid in weight loss and boost metabolism.

Said study was published in the European Journal of Nutrition. The researchers discovered that black tea stimulates the production of good bacteria in the gut and modifies the body’s energy metabolism in the liver via gut metabolites.

The team of researchers from the University of California gathered their data following a series of experiments conducted on mice.

Based on their research, the researchers claimed that both green and black tea are beneficial in supporting weight loss, as both reduce the amount of gut bacteria that is usually linked with obesity while increasing the type of bacteria that is qualified for producing lean body mass.

The researchers grouped the mice into four and put them on different diets as follow:

• Low-fat, high-sugar
• High-fat, high-sugar
• High-fat, high-sugar and green tea extract
• High-fat, high-sugar and black tea extract

For a period of four consecutive weeks, their weight loss was monitored and eventually, the researchers found out that those mice that were given green or black tea extract had lost the same amount of weight as those mice that were placed on low-fat diet.

However, the mice on the black tea extract diet likewise revealed an increase in Pseudobutyrivibrio – a bacterium which particularly targets the metabolism.

While many studies have showcased the health benefits of green tea, this study is one of the first to reveal the benefits of polyphenols present in black tea such as English Breakfast Tea and British Morning Tea.

Such compounds encourage the production of short-chain fatty in the gut, which the study proves has been seen to boost the body’s metabolic rate.

In a statement released by the study’s lead author, Susanne Henning, a human nutrition professor at UCLA, she claimed:

“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.. 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.. For black tea lovers, there may be a new reason to keep drinking it,”
