Drinking Green Tea Lowers Body Weight


 Compelling evidence presented in the journal Nutrition Research makes the irrefutable connection among green tea consumption, lowered body weight and reduced levels of dangerous belly fat. Drinking between 5 and 8 cups of green tea each day was shown to lower body weight by 5.6% and to decrease abdominal fat stores by 17.8% over a period of 8 weeks. Green tea consumption has long been associated with lowered risk of cancer, metabolic syndrome and heart disease. This research provides compelling evidence that green tea boosts metabolism to target fat stores and assists weight loss efforts.

Green tea extracts have been researched extensively over the past decade and are shown to dramatically lower the risk of Alzheimer`s disease and dementia, cardiovascular disease and many forms of cancer. Additional studies have shown that the polyphenols in green tea are a significant factor in improved oral health and can provide necessary support for weight management and control. Green tea is composed of four primary polyphenols (epigallocatechin gallate (EGCG), epigallocatechin, epicatechin gallate, and epicatechin) that are shown to influence genetic signaling and metabolic rate.


The study was conducted by Polish researchers and used an animal model to determine weight loss and fat accumulation characteristics. The researchers also analyzed cardiovascular risk factors and atherogenesis over an 8 week period. The animals were fed a high fat diet and drank green tea made from either a 1.1% or 2% extract of the active phenolic compound. The results indicate that body weight and fat reduction are dose dependent with maximum results (5.6% lower body weight, 17.8% fat reduction) achieved with the 2% extract.



Researchers also found that both concentrations of green tea extract reduced atherogenesis (initial loss of coronary artery elasticity leading to artery hardening and future heart disease) by 14.3% compared to non-supplemented subjects. The study authors did not determine the mechanism for cardiovascular risk reduction. Prior research has shown that the potent antioxidant content of green tea is responsible for significantly lowered levels of oxidized LDL cholesterol and increased particle size that are consistent with reduced heart disease risk.This study used the equivalent of 5 to 8 cups of green tea consumed each day to achieve optimal weight management, fat reduction and cardiovascular risk reversal. Researchers found that the green tea concentration is important to achieve optimal weight lowering results. Drink 6 cups of green tea daily to help prevent coronary artery disease, assist weight loss and boost fat reduction efforts.


Green tea aqueous extract reduces visceral fat and decreases protein availability in rats fed with a high-fat diet.

Green tea is associated with beneficial health effects mainly because of its body fat-reducing and hypocholesterolemic activities, but an effective dose without pronounced influence on protein availability is unknown. The objective of this study was to examine the hypothesis that green tea aqueous extract (GTAE) depending on dose improves cardiovascular risk indicators such as body weight, visceral fat content, and atherogenic index of plasma and does not have unfavorable effect on protein availability in rats fed with a high-fat diet. The rats fed with a high-fat diet enriched with 1.1 and 2.0% GTAE for 8 weeks had significantly (P < .05) lower atherogenic index (in both groups, about 14.3%). Only administration of 2.0% GTAE significantly (P < .05) decreased body weight gain (5.6%) and prevented visceral fat accumulation (17.8%) in rats. However, considerably (P < .05), reduction in the digestion of protein (but not fat) was observed in both GTAE groups (1.1% GTAE: 82.6% ± 1.8%; 2.0% GTAE: 84.3% ± 0.8%) when compared to the control (93.3% ± 1.5%). It was concluded that GTAE may have preventive effects on the accumulation of visceral fat but only in higher doses. Although both doses improved cardiovascular risk indicators, they, in addition, significantly inhibited protein digestion.
