Come on, let's seriously define obesity.
Let Xiao Hu tell you what is true? Obesity.
Body mass index (BMI) is an important international standard to measure obesity and health.
The calculation formula is as follows: body mass index = weight/height squared (kg/㎡).
Determine if you really need to lose weight, and then see how drinking tea can help you lose weight.
First of all, we should know that the root cause of obesity is the imbalance of energy intake and output, which leads to excessive fat accumulation in the body. Many factors such as genes, endocrine, physiology, nutrition and social environment will cause energy imbalance.
The mechanism of reducing obesity is nothing more than the following:
So how does drinking tea play a role in losing weight?
In fact, tea contains a lot of tea polyphenols (18%-36%), and catechin is an important component of tea polyphenols (about 70% of tea polyphenols).
Friends who have bought pure tea drinks in convenience stores don't know if they have noticed that some tea packages indicate the content of tea polyphenols or catechins.
Epigallocatechin gallate (EGCG) is a kind of catechin, and it is a great contributor to the weight loss effect of tea!
So how does EGCG lose weight?
Let the small pot come for you:
First, reduce the survival rate of preadipocytes.
Preadipocytes are usually understood as precursor cells that will become adipocytes.
Researchers at Seoul National University in South Korea are treating 3T3-L 1 mouse preadipocytes with EGCG. The results showed that EGCG could significantly reduce the activity of preadipocytes.
? It means to kill fat cells in the cradle!
Second, increase energy consumption?
Our body fat consists of white adipose tissue (WAT) and brown adipose tissue (BAT). Water is mainly used to store energy, while bats are mainly used to generate heat. Thermogenic activity usually activates the transient receptor potential (TRP) on sensory neurons through cold signals, which transmit signals to the brain and activate sympathetic nerve activity.
EGCG can activate TRP channels on neurons, thus promoting the thermogenesis of brown adipocytes.
? So this is why it is easy to get hungry after drinking tea.
Third,? Inhibition of lipid synthesis
Studies at the University of Merino in Italy found that lovastatin, a compound found in fungi and Pu 'er tea, can inhibit 3- hydroxy -3- methylglutaryl-CoA reductase in the liver, which is the rate-limiting enzyme for cholesterol synthesis, thus reducing cholesterol synthesis.
At the same time, EGCG can also inhibit HMG-CoA in vitro, which may help to reduce the probability of hyperlipidemia and lipid deposition.
? Every time I cross talk with Beckham, it's her, not me. Is it because I love tea and she doesn't?
Fourth, increase the sensitivity of islet β cells and insulin.
Mashhad University in Iran found that catechins can increase the number of pancreatic β cells in animal models of type II diabetes.
Pancreatic β cells can release insulin after food intake. If high school students haven't forgotten, they should remember that insulin is a hormone used to lower blood sugar after eating food.
However, hypertrophic adipocytes will produce proinflammatory cytokines, which will lead to dysfunction, apoptosis and necrosis of β cells, and then affect insulin secretion, which is one of the reasons why fat paper people are prone to diabetes.
Taiwan Province Institute of Traditional Chinese Medicine gave 500mg of green tea extract to patients with type II diabetes, three times a day, for a total of 16 weeks. Compared with the control group, the insulin sensitivity of the experimental group was significantly improved.
? Let the potbellied people around you drink tea quickly!
Thanks to the mice who drink too much spicy tea. I wonder if they like tea?
Having said so much about the mechanism of action, if you ask me: Is it useful for me to lose weight just by drinking tea?
The pot of conscience must remind everyone that if you want to lose weight, please eat reasonably and keep exercising. Drinking tea can only be used as an aid.
The following are the real human test results of the small pot:
Drinking tea alone is easy to get hungry.
I believe many people have this experience. Personally, I especially like to drink black tea and raw tea, and I am hungry.
I really want to eat meat ! !
Eating meat at night is easy to get fat. .....
Xiao Hu always swears that he will never drink night tea again after he dies. He drinks too much at night, tossing and turning in bed, hungry, but his mind is extremely agile!
So don't drink tea at night! ! !
Don't drink tea at night! ! !
Don't drink tea at night! ! !
Of course, those students who have nothing to do after drinking tea should ignore it. ....
Eat greasy food and drink some tea.
If you feel guilty and a little greasy after eating meat during the day, drinking tea is a good choice. I'm not talking about milk tea or milk tea, otherwise it will only be more supportive. Soak a cup of hot tea, clear the intestines and soothe the stomach, and you can lose weight (chi) and (rou) happily at the next meal.
Third, don't drink tea immediately after meals.
After food enters the stomach, the first step of digestion in the stomach is to secrete a lot of gastric acid. If you drink a lot of tea at this time, it will dilute the concentration of gastric acid, affect the activity of pepsin, and make it difficult for food in the stomach to fully chyme into the duodenum. This will not only increase the burden on the stomach, but also affect the absorption of nutrients by the duodenum, which will easily cause digestive tract diseases such as gastrointestinal tract over time.
But to tell the truth, the small pot has the habit of making tea before eating. After eating, the water temperature just drops, and then it is very gratifying! Change it! Change it! !
