Black tea is one of the most consumed infusions in the world.
This is not only because, unlike other variants such as green tea, it maintains its flavor for years, but also because it is capable of providing many health benefits, among which the ability to help control or lose weight stands out. weight.
What is black tea?
Black tea is a beverage obtained from the leaves of the plant. camellia sinensis. These are used to produce various varieties of tea, including green, oolong or white.
Black is distinguished from the others because it undergoes a complete oxidation process, which guarantees a unique color and flavor.
Its popularity and incidence in the diet throughout the world led many experts to begin studying its effects on the body.
Different investigations agreed that its consumption is associated with a better distribution of fat, as well as a significant reduction in waist circumference. This is due to the following effects it has on the body:
Black tea tends to have a higher concentration of caffeine than its peers. It works by raising body temperature in a process known as thermogenesis, which triggers reactions in the human body that result in fat burning and better metabolism of nutrients.

This translates into an important help for the body to function better during exercise and to lose weight faster.
The intestinal microbiota refers to the microorganisms that live in our intestine. These have been studied for years for their effects on different physical and chemical processes that occur in the body.
For example, an animal study published in European Journal of Nutrition, showed that both black and green tea changed the ratio of gut bacteria. The percentage of bacteria associated with obesity decreased, while the bacteria associated with lean body mass increased.
“Green tea polyphenols were known to be more effective and offer more health benefits than black tea polyphenols, as the chemicals in green tea are absorbed into the blood and tissue. Our findings suggest that black tea, through a mechanism specific to the gut microbiome, may also contribute to good health and weight loss in humans,” said Susanne Henning, one of the study’s authors.
Naturally, black tea is a calorie-free drink (1 calorie per 100 grams), so many researchers have studied how it can help control or lose weight.
According to experts, drinking this infusion during or before a meal can stimulate the feeling of satiety, avoiding overeating or suffering from the popular “binge” episodes. At the same time, it allows you to avoid other options that are not healthy, such as artificial fruit juices or sugary drinks.
The oxidation process ensures that black tea contains more caffeine than its variants (between 2 and 4%). In addition, this infusion is rich in antioxidants, such as polyphenols and catechins, and in two healthy compounds: theaflavins and thearubigins.
By consuming it regularly, in addition to improving weight control, you can also:
- Increase alertness, attention and performance.
- Develop higher bone density.
- Increase the moisture, brightness and strength of the skin.
- Balance the intestinal microbiota.
- Take care of oral health.
- Fight hardening of the arteries.
Moderate intake of black tea is safe for most adults. However, when it is high (more than five cups daily), it can cause side effects due to caffeine.
Headache, nervousness, sleep problems, vomiting, diarrhea, irritability, irregular heart rate, tremors, heartburn, dizziness, ringing in the ears, seizures, and confusion have been reported in such cases.
To enhance its benefits on body weight, combine a moderate consumption of black tea with a healthy, balanced and sustainable diet, along with regular exercise routines or programs.
