What is green tea?
Green tea is a type of tea that is made from the leaves of the Camellia sinensis plant, which is native to China and India. Unlike black tea and oolong tea, which are fermented, green tea is not fermented and undergoes minimal oxidation. This preserves the natural antioxidants and phytochemicals that give green tea its distinctive color, flavor, and health benefits.
Green tea contains a number of compounds that are thought to be responsible for its weight loss effects. These compounds include caffeine, catechins, and EGCG.
Green tea and weight loss
Green tea has been shown to boost metabolism, promote fat burning, and reduce appetite. It may also help to reduce the amount of abdominal fat, which is a harmful type of fat that is linked to an increased risk of heart disease and other health problems.
According to a meta-analysis of 15 randomized controlled trials, green tea consumption was associated with a significant reduction in body weight, body mass index (BMI), waist circumference, and body fat percentage. Another meta-analysis of 11 studies found that green tea catechins, especially EGCG, were effective in reducing body weight and maintaining weight loss.
How green tea works
Green tea contains a number of compounds that are thought to be responsible for its weight loss effects. These compounds include caffeine, catechins, and EGCG.
Caffeine
Caffeine is a stimulant that can boost metabolism and energy levels. It can also increase the breakdown of fat and enhance the effects of other fat-burning compounds, such as catechins. Caffeine can also suppress appetite and reduce food intake.
Catechins
Catechins are antioxidants that can help to reduce inflammation and oxidative stress, which are linked to obesity and metabolic disorders. Catechins can also stimulate the production of norepinephrine, a hormone that triggers the release of fat from fat cells. Catechins can also inhibit the activity of enzymes that are involved in fat synthesis and absorption, such as lipase and amylase.
EGCG
EGCG is a type of catechin that is particularly effective at promoting fat burning. EGCG can enhance the activity of hormone-sensitive lipase, an enzyme that breaks down fat stored in fat cells. EGCG can also increase the expression of genes that are involved in thermogenesis, the process of generating heat from burning calories. EGCG can also modulate the levels of hormones that regulate appetite and energy expenditure, such as leptin, ghrelin, and insulin.
How to consume green tea for weight loss
Green tea can be consumed in a variety of ways, including:
Drinking green tea as a beverage
This is the most common and traditional way of consuming green tea. You can brew green tea leaves or tea bags in hot water for about 2 to 3 minutes, depending on your preference. You can also add lemon, honey, or mint to enhance the flavor and health benefits of green tea. You can drink up to 3 to 4 cups of green tea per day, preferably before or between meals, to maximize its weight loss effects.
Taking green tea supplements
This is a convenient and concentrated way of consuming green tea. You can take green tea capsules, tablets, or powders that contain standardized amounts of green tea extract, which is rich in catechins and EGCG. You can follow the dosage instructions on the label, but generally, you can take up to 500 to 1000 mg of green tea extract per day, divided into two or three doses, preferably before meals.
Eating green tea extract powder
This is a novel and versatile way of consuming green tea. You can use green tea extract powder, which is a fine and soluble powder that contains high levels of catechins and EGCG, to add green tea flavor and benefits to your food and drinks. You can sprinkle green tea extract powder on your yogurt, oatmeal, smoothies, salads, soups, or baked goods. You can also mix green tea extract powder with water, milk, or juice to make a green tea drink. You can consume up to 2 to 3 grams of green tea extract powder per day, preferably before or between meals.
Other health benefits of green tea
In addition to its weight loss benefits, green tea has also been linked to a number of other health benefits, including:
Improved heart health
Green tea can lower the levels of bad cholesterol (LDL) and triglycerides, and raise the levels of good cholesterol (HDL), which can prevent the buildup of plaque in the arteries and reduce the risk of heart attack and stroke. Green tea can also lower blood pressure and improve blood vessel function, which can prevent hypertension and atherosclerosis.
Reduced risk of cancer
Green tea can inhibit the growth and spread of cancer cells, and induce apoptosis, or programmed cell death, in various types of cancer, such as breast, prostate, lung, colon, and skin cancer. Green tea can also protect against DNA damage and oxidative stress, which are the main causes of cancer. Green tea can also modulate the immune system and enhance the effectiveness of chemotherapy and radiation therapy.
Improved cognitive function
Green tea can improve memory, attention, and learning, and prevent cognitive decline and dementia, by enhancing the activity of neurons and neurotransmitters in the brain, such as acetylcholine, dopamine, and serotonin. Green tea can also protect the brain from neurodegeneration and neuroinflammation, which are associated with Alzheimer’s disease and Parkinson’s disease.
Reduced stress levels
Green tea can reduce the levels of cortisol, the stress hormone, and increase the levels of alpha waves, which are associated with relaxation and alertness, in the brain. Green tea can also improve mood and reduce the symptoms of depression and anxiety, by modulating the levels of serotonin and dopamine, the happiness hormones, in the brain.

Other FAQs answered on green tea and weight loss
Here are some of the most frequently asked questions on green tea and weight loss, and their answers:
1. Does green tea have calories?
Green tea itself does not have any calories, as it is mostly water. However, if you add sugar, honey, milk, or cream to your green tea, you will increase the calorie content of your drink. Therefore, it is best to drink green tea plain or with a low-calorie sweetener, such as stevia, to avoid adding extra calories to your diet.
2. Does green tea reduce belly fat?
Green tea can help to reduce belly fat, which is also known as visceral fat, by increasing the breakdown and utilization of fat, especially in the abdominal area. Green tea can also reduce the inflammation and oxidative stress that are associated with belly fat, which can reduce the risk of metabolic syndrome, diabetes, and cardiovascular disease.
3. Which green tea is best for weight loss?
There are many types of green tea available in the market, such as sencha, matcha, jasmine, and oolong. However, the best green tea for weight loss is the one that has the highest concentration of catechins and EGCG, which are the main fat-burning compounds in green tea. According to a study, the highest levels of catechins and EGCG were found in matcha, followed by sencha, jasmine, and oolong. Therefore, matcha may be the best green tea for weight loss, as it can provide the most benefits in the least amount of tea.
4. What is the best time to drink green tea for weight loss?
The best time to drink green tea for weight loss may vary depending on your individual preferences and goals. However, some general guidelines are:
- Drink green tea before or between meals: This can help to boost your metabolism, suppress your appetite, and prevent overeating. It can also help to improve your digestion and absorption of nutrients.
- Drink green tea before or after exercise: This can help to increase your energy, performance, and fat burning during and after your workout. It can also help to reduce muscle soreness and inflammation.
- Drink green tea in the morning or afternoon: This can help to enhance your alertness, focus, and mood throughout the day. It can also help to prevent the afternoon slump and cravings for sugary snacks.
- Avoid drinking green tea in the evening or at night: This can interfere with your sleep quality and quantity, as green tea contains caffeine, which can keep you awake and restless. It can also cause dehydration and frequent urination, which can disrupt your sleep cycle.
