Green tea contains antioxidants called catechins that promote weight loss. Catechins stimulate the production of brown fat, which burns calories to produce heat through thermogenesis. Studies show green tea can help burn fat and reduce body fat when consumed regularly. Green tea has about 30 mg of caffeine per cup, less than coffee or black tea, and up to 300 mg of caffeine per day is considered safe for most adults. Drinking 3-4 cups of green tea daily may aid in fat loss when combined with calorie reduction and exercise.

Both green tea and black tea come from the same tea plant, Camellia sinensis. The
leaves are simply processed differently. Green tea leaves are not fermented; they
are withered and steamed. Black tea undergoes a crushing and fermenting process.
Both black and green tea not only has their own distinctive colors, flavors and
aromas but also their own specific benefits
Some terms explained -
Polyphenols
Polyphenols are antioxidants in plants that may have health benefits for .The two
classes of polyphenols are non-flavonoids and flavonoids.

3. Flavonoids
Flavonoids are a most powerful group of antioxidants found naturally in plants.
Flavonoids are one of the reasons fruits and vegetables are so good for you
Catechin
• Catechins are flavonoids found primarily in green tea.
• Catechin is a powerful, water soluble antioxidant that is easily oxidized.
• Catechins are not stable. They deteriorate when come in extended contact
with oxygen, light, moisture and other reactive substances in the
environment.
How Green Tea helps to burn fat
The answer is “Catechins!” . Green Tea contains a powerful antioxidant called
Catechins.
Catechins are responsible for Green Tea’s amazing health benefits. Green Tea
contains 8 times more Catechins than Black tea. Catechins are readily oxidized, and
because of the way black tea is processed, there is very little left in it.
A cup of Black tea contains 5-10 mg of Catechin, compared to Green Tea which
contains 40-90 mg.
Catechins stimulate the body’s own brown fat, which is known to burn excess
calories, becoming heat. The process of this brown fat burning calories and becoming
heat is called thermogenesis.
Catechins promote weight loss by increasing the amount of energy your body uses
and by making it easier for your body to use excess body fat.
The antioxidant benefit of green tea also include these antioxidants protects cells
from free radicals, the damage that can lead to blood clot formation, atherosclerosis
and cancer.
Studies have shown that regular intake of Green Tea can help with fat burning. Ref
