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. Not only that, but it also appears that green tea diets may act as a mild appetite-suppressant because of the presence of caffeine. Caffeine may be harmful for the body since an excess of it can cause heart palpitations, hypertension, and insomnia. However, because green tea diets contain only very low levels of caffeine, there is no danger of experiencing these side-effects.
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.
Green Tea and Weight Loss
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.
