EGCG (epigallocatechin gallate) from green tea increased fat and protein excretion in the feces of mice fed a high-fat diet according to a study from Germany.

EGCG (epigallocatechin gallate) from green tea did not affect food or calorie intake of mice fed a high-fat diet according to a study from Germany.

EGCG (epigallocatechin gallate) from green tea increased fat oxidation, that is the burning of fat, of mice fed a high-fat diet according to a study from Germany.

It also reduced the amount of dietary fat that was incorporated into tissue.

Tea drinkers have less body fat and a smaller waist-to-hip ratio than non-tea drinkers according to a study from Taiwan. People who have been drinking tea at least once a week or more were found to have 19.6 percent less body fat than non-tea drinkers and have a 2.1 percent lower waist-to-hip ratio than non-tea drinkers.

A caffeine-free supplement of EGCG (Epigallocatechin-3-gallate) does NOT increase resting metabolism, nor does it increase thermogenesis following a meal according to a new study from researchers at Colorado State University in Fort Collins, Colorado, USA.

These results were the opposite of what these researchers expected.

“Contrary to our hypothesis, we found no stimulatory effect of short-term administration on either [ resting metabolic rate ] or [the thermic effect of food ], the researchers concluded.

Five servings of oolong tea per day increases the number of calories burned per day by 2.9 percent, or about 66 calories per day, and the amount of fat that is burned by 12 percent in men according to a recent study.

Men drinking one bottle of oolong tea per day lost an average of 5.3 pounds in three months compared to 2.9 pounds for men in the control group according to a study from Japan.

Oolong tea may help to prevent weight gain by increasing the amount of fat that is burned and, surprisingly, by reducing fat absorption in manner similar to the fat-blocking drug Xenical (orlistat) and Alli (orlistat sold over-the-counter) according to mouse study from Japan.

There are three types of tea: black, oolong and green.

Of the three, oolong is traditionally reported to have an weight-reducing effect as well as a cholesterol- and triglyceride-lowering effect according to Han et al (1999).

Green tea catechins (EGCG) reduce body weight by an average of 2.9 lbs according to a meta-analysis of 11 studies.

“[White tea] has been shown to contain the largest amount of catechins, from which EGCG is also present abundantly,” a recent paper notes.

“The amount of caffeine in [white tea] is also substantially larger compared with for instance [green tea].”

“More research is needed to study [white tea’s] effect on thermogenesis.”

After losing 15 pounds in one month on a very-low-calorie diet, people were able to maintain this weight loss either by taking 90 mg of EGCG plus 50 mg of caffeine after each meal, or by eating a high-protein diet containing 100 grams of protein per day, which included 50 grams of a simple protein powder called calcium caseinate according to a study from Maastricht University in Maastricht, Netherlands.

People eating a diet containing adequate protein of only 50-60 grams of protein per day regained 6 pounds during the three months of intended weight maintenance.

Lean people burned the most fat, and obese people burned the least fat according to a new study. “The observed reduction in dietary fat oxidation in subjects with a higher percentage body fat may play a role in human obesity,” the researchers concluded.

Men and women who consumed three servings of a beverage containing green tea, caffeine and calcium, increased the amount of calories burned each day by 106 calories per day or by 4.6 percent according to a new study from researchers from Lausanne University in Lausanne, Switzerland and Purdue University in West Lafayette, Indiana, USA.

A supplement containing green tea catechins, caffeine, capsaicin from hot peppers and the amino acid L-tyrosine increased metabolism in overweight people by 20 calories during the following four hours and increased fat loss by 2 pounds after two months according to a study from A. Belza in Denmark.

A mixture of 100 mg of black tea extract, 100 mg of green tea extract and 1,000 mg of mulberry tea extract decreased carbohydrate absorption by 25 percent according to a new study.

Xenadrine-EFX, a nutritional supplement containing bitter orange, green tea and guarana, did not affect metabolism at rest or during light exercise according to a study from University of Chichester in Sussex, UK.

Green tea increases metabolism by 4 percent per day according to one study.

AN IN VITRO STUDY using brown adipose tissue from a rat found that a preparation of dried tea leaves increased thermogenesis when used alone and more strongly when combined with ephedrine.

“Keemun black tea extract significantly reduced food intake, body weight and blood triglyceride of diet-induced obesity rats via oral administration,” according to a new study from the Graduate School of Chinese Academy of Sciences in Beijing, China.

Epigallocatechin gallate (EGCG), the primary health-promoting ingredient in green tea, dose-dependently inhibits accumulation of fat in fat cells, and increases the rate of programmed cell death of mature fat cells according to a new study from researchers at the University of Georgia in Athens, Georgia, USA.

Epigallocatechin gallate (EGCG), an ingredient in green tea, dose-dependently—in other words, the higher the dose, the larger the effect—reduces body fat and body weight according to a new study in mice.

“An extract of Green tea has thermogenic properties and promotes fat oxidation beyond that explained by its caffeine content,” says obesity researcher Abdul Dulloo, M.D., Ph.D. from the Institute of Physiology at the University of Fribourg in Fribourg, Switzerland.

Oolong tea may help to prevent weight gain by increasing the amount of fat that is burned and, surprisingly, by reducing fat absorption in manner similar to the prescription fat-blocking drug, Xenical (orlistat).

“Green tea extract stimulates brown adipose tissue thermogenesis to an extent which is much greater than can be attributed to its caffeine content per se,” concluded Abdul Dulloo and colleagues in a paper which explains how green tea extract stimulates thermogenesis.
