Can you really lose weight by drinking tea? (Lin Longyong/People's Network)
Why does drinking tea make people hungry faster?
According to Life Times, tea contains caffeine, theophylline and theobromine, which can stimulate gastric acid secretion. Ruihua Shi, director of the Department of Gastroenterology, Zhong Da Hospital affiliated to Southeast University, said in an interview with Health Times that gastric acid can stimulate the human body to secrete a variety of enzymes, hormones and neurotransmitters related to digestion, thus contributing to food digestion. So, after drinking tea, you will be hungry faster.
Can you lose weight by drinking tea?
Does the faster hunger after drinking tea mean that drinking tea can lose weight? In an interview with Life Times, Wang Xingguo, director of the Nutrition Department of Dalian Central Hospital, reminded everyone that drinking tea can't lose weight, because drinking tea only changes the digestion process, not the digestion result. In other words, although people are hungry faster after drinking tea, the energy consumed during eating will not decrease, so it is impossible to lose weight.
In addition, according to the Beijing Morning Post, any weight-loss and lipid-lowering products in the name of tea have little to do with the tea itself. If it really has weight loss effect, it is also because some drugs with weight loss effect have been added. As far as tea itself is concerned, unless you drink too much strong tea every day, people will be too excited to sleep, thus increasing the basic metabolism of the human body, thus causing the effect of "falling off the scale" to some extent. But if you drink strong tea to lose weight, the effect is actually very small, and it is harmful to human health, so it is not recommended that you choose this method.
What's the point of drinking tea?
First, it is not advisable to drink tea on an empty stomach before meals. Because drinking tea on an empty stomach before meals will dilute gastric juice and affect its secretion, which is not conducive to food digestion.
Second, it is not advisable to drink tea immediately after meals. If you drink tea immediately after meals, the tea polyphenols contained in tea can easily react with iron and protein in food, thus affecting the absorption of iron and protein by human body. According to Life Times, the most reasonable time for drinking tea should be half an hour after meals.
Third, don't drink tea before going to bed. Caffeine contained in tea has the function of exciting the central nervous system, and drinking tea before going to bed will make it difficult for people to fall asleep; In addition, tea is also a diuretic, coupled with a large amount of water intake when drinking tea, drinking tea before going to bed will also lead to an increase in the number of trips to the toilet at night, thus affecting the quality of sleep.
