Russia and Germany answered. The study found that drinking 8 grams of oolong tea every day can make half of obese people lose weight. Another study confirmed that drinking 2 cups of oolong tea with high concentration of catechins every day can reduce the weight, waist circumference and body fat rate of obese people after three months. Further research found that green tea and black tea extracts contain some effective components, which can reduce the absorption of food fat, promote the oxidative decomposition of fatty acids and inhibit the activity of lipoxygenase. These effects cannot be completely replaced by caffeine. But be careful. . . Myth 1: The more expensive the tea, the better the weight loss effect. Because the effective weight-loss components of tea are tea polyphenols and theaflavins, as well as caffeine and theophylline, it is necessary to choose tea with high content of these substances, and these factors have nothing to do with the price. Myth 2: Drinking light tea can help you lose weight. Any active substance needs enough dosage to play its health role. In the study of effective weight loss, the daily intake of tea polyphenols is between 90-690mg. Just drinking three or two cups of fragrant light tea won't help you lose weight. Myth 3: The effect of drinking tea to lose weight can be maintained for a long time. Drinking tea may not have a long-term maintenance effect on weight control. Once you stop drinking tea, you will probably regain your weight. Myth 4: Drink a lot of tea at night to lose weight by sleeping less. For people who are sensitive to caffeine, drinking strong tea may affect their sleep, so drinking tea in the morning and in the morning is more appropriate. If you drink tea after 5 pm, it may cause insomnia at night. Reducing sleep will not only improve the weight loss effect, but also increase blood sugar and increase the hormone level that promotes appetite, which is not worth the candle. Of course, if you don't need to lose weight, especially children, it's best to control the amount of caffeine. Advocating drinking light tea is still a healthy formulation for most people. . . I hope the above suggestions can help you. ~ ~ ~ hee hee.
