Green tea powder+yogurt, weight loss method: mix 500 ml yogurt with 3 teaspoons of green tea powder and eat it on an empty stomach. Green tea powder contains catechins, tea polyphenols and caffeine, which has a certain effect on weight loss, but it needs to reach a certain amount. In the study of effective weight loss, the daily intake of tea polyphenols needs to reach 90~690 mg. Green tea powder contains caffeine and other alkaloids. Eating with yogurt on an empty stomach can easily make the intestines absorb too much caffeine, which will cause some people to have hyperthyroidism symptoms such as palpitation, dizziness, weakness of hands and feet, and trance.
