Burning excess body fat by drinking green tea

From the Camellia sinensis plant are extracted the green tea and also the black tea and Oolong tea. Green tea is not fermented, unlike the other two, allowing the conservation of polyphenol, the main responsible for their beneficial effects.

The four major flavonoids in green tea are the catechins, epicatechin (EC), epigallocatechin (EGC), epicatechingallate (ECG) and epigallocatechin gallate (EGCG). In addition, green tea also includes some polyphenols like caffeine, theanine, theaflavin, thearubigin,quercetin, chlorogenic acid, and gallic acid.

In November 1999, the American Journal of Clinical Nutrition published the results of a study at the University of Geneva in Switzerland. Researchers found that men who were given a combination of caffeine and green tea extract burned more calories than those given only caffeine or a placebo.

The EGCG in green tea diet also acts with the compound caffeine. A cup of green tea contains between 15–50 mg of caffeine. The interaction of these two compounds causes green tea diet to promote thermogenesis in the body. It has been noted by a study published in the American Journal of Clinical Nutrition that, with the consumption of green tea diet, the body’s total 24-hour energy expenditure is increased by up to 4%. This is roughly equivalent to losing more than 10 pounds of weight a month. Green tea diet helps increase the body’s metabolic rates.

Both the catechins and the caffeine, which are the major components of green tea, inhibit the enzymes taking role in the pathways, where the norepinephrine is active and affect thermogenesis. Because the central nervous system activity is affected from the norepinephrine concentration, the more norepinephrine activity means the more activity and energy expenditure.

Excess glucose found in the body is turned into fats by the hormone insulin. Because green tea diet has an inhibiting effect on insulin, green tea diet therefore helps keep sugar from being stored as fats and, instead, sends them directly into the muscles for immediate use.

Lipases are the type of enzymes that, among other functions, play a role in metabolizing fats. Gastric and pancreatic lipases are the ones that directly perform this operation. These are also the lipases that the catechins in green tea inhibit. One in vitro study was able to show how a green tree extract containing 25% of the catechins was able to reduce the gastric lipase breakdown of fats by around 96% and partially do the same for pancreatic lipase at 66%.

When fats in food aren’t properly broken down in the digestive system, they can’t get absorbed and just pass through.

Researchers on a study that was investigating the impact of green tea on glucose, insulin and satiety levels found that the participants who took in green tea along with a meal felt fuller and had no desire to eat more. They theorized that the green tea catechins enabled the neurotransmitter called norepinephrine to act longer on the brain and establish the feeling of satiety. The reason is that the catechins blocked the enzyme (catechol-o-methyl-transferase) that breaks down the neurotransmitter.
