Matcha, a finely ground powder of specially grown and processed green tea leaves, has transcended its traditional Japanese roots to become a global health and wellness phenomenon. Celebrated for its vibrant green color, distinctive flavor, and impressive nutritional profile, matcha is now a staple in health stores and coffee shops, appearing in everything from matcha shots and lattes to teas and desserts. This article delves into the preparation of matcha tea, its potential weight loss benefits, and other health advantages, providing a comprehensive guide for both beginners and seasoned enthusiasts.
What is Matcha?
Like other green teas, matcha comes from the Camellia sinensis plant, but its cultivation and preparation set it apart. Farmers shade the plants for most of their growth period, a practice that boosts chlorophyll production, increases amino acid content, and gives the leaves a darker green hue. After harvesting, the stems and veins are removed, and the leaves are ground into a fine powder. This powder is then dissolved in water, offering a unique way to consume the tea and harness its benefits.
Nutritional Profile of Matcha
Matcha distinguishes itself from regular green tea through its preparation and nutritional density, making it a potentially superior aid for weight loss and overall health. Because matcha tea involves consuming the whole leaf, it boasts a higher concentration of fiber, antioxidants, and other beneficial compounds compared to regular green tea.
A single teaspoon of matcha green tea powder contains approximately:
- 12 calories
- 2 grams of carbohydrates
- 2 grams of fiber
- Zero grams of protein and fat
- Bioactive compounds like catechins and lutein
- Vitamin K
Lutein is known for promoting eye health, improving cognitive function, and protecting the skin, while vitamin K is essential for blood clotting and bone health.

Matcha vs. Regular Green Tea
Matcha tea differs from regular green tea in its preparation and nutritional profile, which can make it a superior weight loss aid. When the leaves are harvested, the catechin content is lower than in other types of green tea. However, when dissolved in water, it produces 3 times more catechins.
Health Benefits of Matcha
Matcha is not only a beverage but also a powerhouse of health benefits, largely attributed to its high antioxidant content.
Antioxidant Properties
Matcha is rich in antioxidants, particularly catechins, including epigallocatechin gallate (EGCG), which can help protect against oxidative stress and chronic diseases. Studies have shown that matcha supplements can reduce damage caused by free radicals and enhance antioxidant activity. Including matcha in your diet could increase your antioxidant intake, which may help prevent cell damage and lower your risk of several chronic diseases.
Liver Health
The liver plays a vital role in health, including flushing out toxins, metabolizing drugs, and processing nutrients. Some studies suggest that matcha could prevent liver damage and decrease the risk of liver disease. A review of studies found that drinking green tea was associated with a decreased risk of liver disease. However, some experts note that while matcha may benefit people with nonalcoholic fatty liver disease (NAFLD) by reducing liver enzymes, it may increase liver enzymes in people without NAFLD.
Brain Function
Research indicates that components in matcha could enhance brain function. Studies have shown that consuming matcha improves attention, reaction time, and memory compared to a placebo. Matcha also contains caffeine and L-theanine, which can improve several aspects of brain function. L-theanine alters the effects of caffeine, promoting alertness and helping avoid the crash in energy levels that can follow caffeine consumption.

Cancer Prevention
Matcha contains compounds that have been linked to cancer prevention in test tubes and animal studies. Some laboratory and animal studies have suggested it may help prevent some types of cancer, although more research is needed.
Heart Health
Drinking green tea, which has a similar nutrient profile to matcha, may help protect against heart disease. Green tea consumption has been linked with a lower risk of cardiovascular disease, and some studies have suggested it might help lower the risk of high blood pressure and other complications in people with heart disease.
Matcha and Weight Loss
Matcha has garnered attention for its potential to aid weight loss efforts through various mechanisms.
Boosting Metabolism and Fat Burning
Matcha tea has been found to increase metabolism, which is the process by which the body converts food into energy. Studies have shown that participants who consumed a combination of catechins and caffeine experienced significant increases in fat oxidation and energy expenditure compared to a control group. Some studies show that green tea extract helps increase metabolism and fat burning, both of which may aid weight loss.
Appetite Reduction
Matcha tea contains a type of carbohydrate called EGCG, which has been found to reduce appetite and food intake. Matcha tea is a low-calorie and nutrient-dense beverage that can help curb cravings and promote satiety, which can lead to consuming fewer calories overall.

Energy Levels and Exercise Recovery
Matcha tea is known for its ability to boost energy levels due to its high caffeine content. Unlike coffee, however, matcha tea also contains L-theanine, an amino acid that has been found to promote relaxation and reduce stress. Matcha tea may help reduce fatigue and soreness after workouts, which can help individuals stay active and burn more calories.
Sleep Quality
Matcha tea may help improve the quality of sleep, which is important for weight loss as sleep deprivation has been linked to increased appetite and decreased metabolism. A study has found that L-theanine is a natural and safe sleep aid, improving the quality of sleep.
Scientific Studies and Reviews
A review of scientific studies found that body weight, body mass index, and waist circumference were reduced in obese subjects who consumed green tea. The researchers also point out that green tea consumption should be combined with a healthy, balanced diet and physical activity.
A 2020 review concluded that, together with dietary measures and exercise, taking up to 500 mg per day of green tea for 12 weeks might reduce body mass index.
Matcha and Exercise
A small study found that after three weeks of matcha supplementation, women who went on regular 30-minute walks experienced an increase in fat oxidation. However, researchers note that when regular brisk walks are part of the picture, the “metabolic effects of matcha should not be overstated.”
Gut-Liver Axis Homeostasis
Studies in obese mice have demonstrated that matcha green tea can ameliorate the development of obesity, lipid accumulation, and hepatic steatosis induced by a high-fat diet. Dietary matcha supplementation can restore alterations in fecal bile acid profile and gut microbial composition. Matcha intervention can make significant regulatory changes on the multiple metabolic pathways of hosts involved in glucose, lipid, and bile acid metabolism.
Potential Risks and Considerations
Despite its potential health benefits, it’s best to consume matcha in moderation.
- Caffeine content: Matcha contains more caffeine than green tea. While some caffeine may be beneficial, too much can have adverse effects, such as increasing the heart rate.
- Catechin intake: Some scientists say that a high intake of catechins can cause liver problems, although they note that this is unlikely when people consume green tea as food or drink.
- Contaminants: Drinking matcha may also increase your exposure to contaminants like pesticides, chemicals, and even arsenic found in the soil where the tea plants are grown.
Research has suggested that 338 mg of catechin and EGCG per day is safe for adults to consume, which is the amount in around 4 g of matcha, or 2 level teaspoons. However, the maximum tolerable intake of matcha powder may depend on the individual. To be safe, make sure to consume matcha in moderation. Also, look for certified organic varieties to reduce the risk of impurities.
How to Prepare Matcha Tea
There are many ways to enjoy matcha, so you can choose the one you like best. It can also be incorporated into a range of different recipes.
Traditional Matcha Tea
You can make traditional matcha tea by sifting 1-2 teaspoons (2-4 grams) of matcha powder into your cup, adding 2 ounces (59 ml) of hot water, and mixing it together with a bamboo whisk. You can also adjust the ratio of matcha powder to water based on your preferred consistency.
For a thinner tea, reduce the powder to a half teaspoon (1 g) and mix with 3-4 ounces (89-118 ml) of hot water.
