Many people like to drink green tea because it is good for their health, and it can also help them lose weight. But how does green tea do that, and how much do you need to drink to see the results? Here are some things you should know about green tea and weight loss.
Green tea has some chemicals called catechins, which are good for your body because they can make your metabolism faster and help you burn fat better. Catechins can also lower the swelling, blood sugar, and insulin in your body, which can affect your weight (1).
One of the most important catechins in green tea is EGCG, which can stop an enzyme that makes the hormone norepinephrine less. This hormone tells your fat cells to let go of fat into the blood, where it can be used as energy by your muscles and other parts of your body. By making more norepinephrine, EGCG can make the fat-burning better (2).
Green tea also has caffeine, which can make you more active and make you use more energy. Caffeine and EGCG can work well together, meaning that they can make your metabolism and fat-burning stronger than either of them alone (3).
But drinking green tea alone is not enough to make you lose weight. You also need to eat healthy food and do exercise regularly, as these are the main things that decide how many calories you take in and use up. Green tea can only help you use up a little more calories than you take in, which is needed for weight loss, but not enough by itself.
The amount of green tea you need to drink to see the benefits may be different for different people, depending on things like your weight, age, gender, and genes. Some studies have said that drinking three to four cups of green tea a day can help you lose weight, especially if you drink it before or while you eat, as it can make you feel full and eat less (4)(5). But drinking too much green tea can also have some bad effects, such as not sleeping well, feeling nervous, feeling sick, and having stomach problems, because of its caffeine and tannin. So, it is better to drink no more than five cups of green tea a day, and not drink it too late at night or if you don’t like caffeine (6).
To sum up, green tea is a good drink that can help you lose weight by making your metabolism and fat-burning faster, but only if you also eat well and exercise. The best amount of green tea for weight loss may be different for different people, but it is usually good to drink three to four cups a day, before or while you eat, and not drink more than five cups a day or drink it too late at night. By doing these things, you can get the good things from green tea and reach your weight loss goals.
