Lose weight from consuming tea?
There are a few types of tea that can actively help you lose weight. This is shown by current studies by the University of California in Los Angeles. For example, black and green tea can affect gut bacteria. The fattening bacteria decreased after the regular consumption of tea.

Scientists at the University of California, Los Angeles (UCLA) found in their current study that the consumption of black tea can have various health benefits. For example, tea affects the energy metabolism in the liver through a change in intestinal metabolites. The researchers published the results of their study in the European Journal of Nutrition.

Black tea and green tea can affect the ratio of intestinal bacteria
The study found that both black and green tea change the ratio of intestinal bacteria in animals. The percentage of bacteria associated with obesity decreased in the animals. In addition, the bacteria associated with a leaner body mass increase.

Tea can change the energy metabolism in the liver
Earlier studies have shown that certain chemicals in green tea (polyphenols) are absorbed by the body and change the energy metabolism in the liver. The results of the new study found that black tea polyphenols are too large to be absorbed in the small intestine. This stimulates the growth of intestinal bacteria and the formation of short-chain fatty acids. This special type of bacterial metabolite can change the energy metabolism in the liver.

Green tea polyphenols enter the blood and tissues
“It was already known that green tea polyphenols are more effective and offer more health benefits than black tea polyphenols. This is because chemicals from green tea are absorbed into the blood and tissue, ”explains the author Dr. Susanne Henning from the UCLA Center for Human Nutrition in a press release.

Tea can improve people's wellbeing
“Our new findings suggest that black tea can change the gut microbiome through a certain mechanism. This can contribute to improved health and weight loss in humans, ”added the expert. The results of the study show that so-called prebiotics are present in both green and black tea. "These substances can induce the growth of good microorganisms that contribute to a person's well-being," explains Dr. Henning continues.

Tea consumption resulted in weight loss in the study
For the study, four groups of mice were given different forms of nutrition, and extracts of green tea or black tea were supplemented in two animals. After a period of four weeks, the weight of the mice that had previously received green or black tea extracts decreased, the scientists explain. The weight loss was comparable to the mice on a low-fat diet during the study.

Effects of consuming tea extract
The researchers also collected samples from the large intestine of the mice (for measuring the bacterial content) and the liver tissue (for measuring fat deposits). When the mice ingested some type of tea extract, there were fewer types of bacteria associated with obesity. In addition, more bacteria were found that are associated with a lean body mass, say the doctors. However, there was an increase in a type of bacteria called pseudobutyrivibrio in the mice that consumed the black tea extract. This could explain the differences in how black tea and green tea change energy metabolism, the researchers explain. The results found indicate that the health benefits of green tea and black tea go beyond their antioxidant benefits and that both teas have a strong impact on the gut microbiome, according to author Dr. Zhaoping Li.
