Diet Some teas can help tremendously with weight loss

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

The researchers from the University of California, Los Angeles (UCLA) found in their recent research that consuming black tea has several health benefits. For example, tea affects the energy metabolism in the liver by altering intestinal metabolites. The researchers published the results of their study in the journal 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 alter 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
Previous studies have already shown that certain chemicals in green tea (polyphenols) are absorbed by the body and alter 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 particular type of bacterial metabolite can alter the energy metabolism in the liver.

Green tea polyphenols enter blood and tissues
"It has been known that green tea polyphenols are more effective and have more health benefits than black tea polyphenols. This is because green tea chemicals are absorbed into the blood and tissues, "explains Dr. Susanne Henning from the UCLA Center for Human Nutrition in a press release.

Tea can improve the well-being of people
"Our new findings indicate that black tea can alter the intestinal microbiome through a mechanism of action. This can contribute to improved health and weight loss in humans, "adds 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 the well-being of a person," explains Dr. Henning continues.

Consumption of tea led to weight loss in the study
Four groups of mice were given different diets for the study, and two animals were supplemented with extracts of green tea or black tea. After a period of four weeks, the weight of the mice, which had previously received green or black tea extracts, decreased, the scientists explain. The weight loss was comparable to the mice who had a low-fat diet during the study.

Effects of consuming tea extract
In addition, the researchers also collected samples from the colon of the mice (for measuring the bacterial content) and the liver tissue (for measuring fat deposits). When the mice ingested some kind of tea extract, there were fewer types of bacteria associated with the development of obesity. In addition, more bacteria were found, which are associated with a lean body mass, say the doctors. However, in the mice that consumed the black tea extract, there was an increase in one type of bacteria called pseudobutyrivibrio. This may explain the differences in how black tea and green tea alter energy metabolism, the researchers explain. The findings 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 gut microbiota, according to author.
