  • Tea, the second-most popular drink in the world, behind water, has its origin dating

  • way back to 4,000 years ago in China.

  • And one of the earliest types of tea is green tea, which you'll find in pretty much everywhere

  • in the world.

  • Its extreme popularity is owed to the extravagant amounts of health benefits it contains.

  • And, by and large, these benefits are definitely true and researched extensively.

  • From preventing cancer to just making you feel better, there's no doubt that green tea

  • can do amazing things for your health.

  • In this video, we're just going to focus on its properties pertaining to exercise and

  • fat loss.

  • A green tea leaf has two substances that are the primary players providing the highest

  • amount of health benefits.

  • The first one is very obvious and exists in pretty much all teas, and that is caffeine.

  • At about 75 milligrams per cup, it definitely trails the 150 milligrams from the king of

  • all caffeinated beverages, coffee, but it's still quite a respectable amount and still

  • deliver quite the caffeine kick if you drink two cups in the morning.

  • But one thing that green tea has that coffee doesn't are catechins.

  • Roughly one third of a green tea leaf is composed of four different catechins.

  • We have epicatechin, epicatechine gallate, epi-gallocatechin, and by the most important

  • catechin, epigallocatechin gallate.

  • Woo, that's a lot of epi gallo everything.

  • Once again, epigallocatechin gallate, also known as EGCG, appears to be the most potent

  • in regards to all four catechins.

  • And its effects are simply outstanding.

  • EGCG has the ability to inhibit COMT, an enzyme that degrades catecholamines.

  • Catecholamines are hormones used to increase muscle contraction, and also release energy

  • sources into the bloodstream, such as glucose and fatty acids.

  • By inhibiting COMT, EGCG stops it from inhibiting the effects of catecholamines, which ultimately

  • means stronger muscle contraction as well as increased lipolysis, aka fat breakdown.

  • And the cool thing is that when paired with caffeine, the effects of catecholamines are

  • further accelerated, since caffeine has shown to increase catecholamine production.

  • So caffeine and EGCG are kind of like a tag team fighting against fat.

  • But there's a big catch here.

  • Studies have shown people who've build up an intolerance to the effects of caffeine,

  • also see a wide drop in the effects of EGCG.

  • So if you've been downing a lot of coffee for the past few years and have recently decided

  • to switch to green tea, the benefits of increased weight loss as well as exercise performance

  • might not be there for you.

  • That also means the more you're not used to caffeine, the more you benefit from the fat

  • burning and performance increasing effects.

  • And one extra "benefit" of EGCG is how it might inhibit the body's absorption of carbohydrates.

  • Some studies show that EGCG does in fact suppresses the effects of a glucose transporter protein

  • called GLUT4, which means more carbs coming out of your back end.

  • The effects are only to a small degree, but for some, that might be worthy enough.

  • In order to achieve these benefits from green tea, however, you're gonna have to drink quite

  • a lot.

  • Fat burning effects usually kicks in at roughly 400 milligrams of EGCG consumed.

  • A cup of green tea has roughly 50 milligrams of EGCG.

  • Do the math and that means you're drinking at least 8 cups of green tea.

  • For some, that's actually not hard at all, especially since green tea is mostly water

  • and can serve as a water alternative.

  • And in case you're concerned with tea possibly being a diuretic, aka make you pee more, when

  • compared to water, studies show that urination levels are roughly the same.

  • And remember that green tea is usually effective only if you are sensitive to caffeine, and

  • it's best to drink on an empty stomach.

  • That being said, if there ever was a true superfood, or super drink, green tea perhaps

  • might be taking that title.
