Using Green Tea in Weight Loss Programs

Posted on/at 7:35 AM by Feliciana

There are countless health benefits associated with drinking green tea. For centuries, the Chinese people have been drinking and using green tea as cure for several ailments. Today, cancer prevention, weight loss, antioxidant applications, anti-inflammatory and anti-microbial properties are only a few of the proven benefits contained within a single cup of green tea or a capsule of green tea extract.

Green Tea: An Introduction

Green tea comes from the plant native to Asia called Camellia sinensis. This plant is rich in the green tea substance called epigallochatechin gallate or EGCG. Green tea’s EGCG is the substance responsible for destroying free radicals in the body which are the number one causes of aging and diseases. The antioxidant EGCG in green tea also helps in lowering down cholesterol levels.

Green Tea for Weight Loss Programs

A university study conducted by American and Swiss scientists show that green tea can be used in weight loss programs. Using ten healthy young men as subjects for their weight loss program, the scientists compared the difference in energy expenditures of green tea and that of caffeine or standalone placebo. The results show that green tea boosts energy expenditure by a significant four percent increase. This led many people to believe that green tea can have a significant impact on increasing the efficacy of weight loss programs.



Green tea is a great alternative for people who are on weight loss programs because it can help them lead a healthier lifestyle. For instance, instead of drinking coffee and cream which area high in calories, green tea weight loss programs can not only save you from taking in too much calories but also let you take in several healthful substances like polyphenols and flavonoids. Green tea also contains a small amount of caffeine, a key substance used in most weight loss programs because of its appetite-suppressant properties.

Other studies show that green tea in weight loss programs can help reduce fat by inhibiting the effects of insulin. Insulin is responsible for converting glucose into energy for the body to be stored into fat. By delaying insulin, green tea weight loss programs enable sugar to be sent directly to the muscles for instant use, thus preventing fats from forming.

Green tea in weight loss programs can also promote thermogenesis, the process by which the body burns fat and releases calories. This process is brought on by the interaction of the caffeine content and catechin polyphenols present in green tea. This is why weight loss programs based on green tea is an effective way to stimulate metabolic rates.

No supplement or weight loss program is known to work miracles. However, studies do indicate that green tea have many benefits in store for those enrolled in weight loss programs.

The Weight Loss Benefit of Green Tea

For 4,000 years, Asians have regarded green tea as something more than just a beverage. Green tea was used as herbal medicine and treatment for everything from headaches to depressions and even to weight loss.

Researches have been conducted over the last few years to identify what compound present in green tea makes it a potent health drink. The scientists have found that green tea contains several antioxidants which are responsible for many of green tea’s health benefits, including weight loss benefit.



A research study by American and Swiss scientists on the weight loss benefit of green tea was concluded and the results of which were published in the American Journal of Clinical Nutrition and Urology. During the course of their study, they have found that green tea contains certain compounds that contribute to its weightt loss benefit.

Lead researcher, D. Abdul Dulloo said in a press release that there are only two ways to achieve weight loss – either reduce energy intake or increase energy expenditure. Green tea, it seems, has compounds that can increase the body’s normal metabolism rate, thus giving it its weight loss benefit.

At the University of Geneva, where the study was conducted, Dr. Dulloo and his colleagues experimented on ten healthy young men. They theorized that the main contributor to green tea’s weight loss benefit is its caffeine content. To test this hypothesis on green tea’s weight loss benefit, they placed the study’s participants on a typical “Western” diet which is about forty percent fat, thirteen percent protein, and forty-seven percent carbohydrates.

Thrice everyday, the researchers measured their subjects’ energy expenditure (the measurement used in determining the number of calories burned in 24 hours) and monitored their respiration quotient to find out how well they utilized their carbohydrates, proteins, and fats.

When they interpreted the data they collected, they found out that the men receiving regular dosages of green tea extract showed a significant increase in their 24-hour energy expenditure and a reduction in their respiration quotient (which means that more fat is burned, thereby achieving maximum weight loss). On the other hand, those men who were only given caffeine or placebo with every meal showed only minimal increases in their metabolism rates.

The scientists construed that the substance catechin polyphenol present in green tea adds to its weight loss benefit. These substances in green tea may alter how the body uses the hormone norepinephrine which is responsible for increasing the metabolism rate, thus leading to weight loss.

In their conclusion, the scientists inferred that green tea owes its weight loss benefit to the presence of antioxidants and the substance catechin polyphenol. These substances help increase fat and calorie burning and optimize weight loss.

Green Tea Extract and Weight Loss

Posted on/at 2:15 AM by Feliciana

Green tea has always been known to have several health benefits, but who knew that it could contribute to weight loss as well?

A recent study published in the American Journal of Clinical Nutrition show that green tea extract can increase metabolism and fat oxidation of the body. In theory, scientists believe that the weight loss benefits of green tea extracts are due to their caffeine content but the results of the study show otherwise as they discovered that green tea extracts have weight loss benefits beyond that of caffeine.

In their study, the researchers administered alone the same amount of caffeine as that in green tea extracts but found that it did not make any significant changes in the body’s overall energy expenditure. This led them to conclude that green tea extracts have ingredients in them that actively interact with each other, promoting increased metabolism and fat oxidation that lead to weight loss.




Further findings indicated that a certain compound found in green tea extracts might be the ingredient that causes weight loss. These green tea extract compounds called Flavonoids may alter the way the body uses norepinephrine, a hormone that monitors how calories are burned. When flavonoids interact with other green tea extract ingredients, more calories are burned thus contributing to weight loss.

Another ingredient that actively contributes to the weight loss benefits of green tea extracts is the compound catechin polyphenols. These compounds also interact with other green tea extract ingredients in order to promote weight loss by fat burning and thermogenesis (a process of losing energy by daytime heat).

The great thing about the weight loss benefit of green tea extracts is that it does not have any adverse side-effects. Unlike other herbal products like ephedra and prescription drugs for obesity, green tea extract does not increase the speed of heart rates or raise blood pressure. In this regard, green tea extract is an effective and safer alternative to other weight loss products which may cause harm to the user.

The study conducted by the University of Geneva on the weight loss benefit of green tea extract implicated that green tea extract can also help thyroid patients. According to dietitian Lynn Moss, M.S., R.D., green tea extract is a healthier choice for people with thyroid who may be too sensitive to stimulants. Green tea extract can promote weight loss by increasing metabolism without over stimulating the adrenal glands.

A common beverage all throughout Asia, green tea has recently gained popularity in the West. Further researches were conducted to identify other health benefits of green tea extracts aside from weight loss. It was found that certain green tea extract compounds can significantly reduce the risk of heart disease, cancer, and even ulcers.
