In fact, it may have some benefit in this regard, but there are some special precautions to take with thyroid problems.

How Green Tea Helps You Lose Weight

When your thyroid doesn't produce enough hormones, your metabolism slows down, reducing the number of calories you burn and often leading to weight gain. Simply put, green tea can help increase your metabolic rate so you burn more calories.

In a 2008 study published in the American Journal of Clinical Nutrition , green tea extract was found to significantly increase energy expenditure and have a significant effect on fat burning. While some of the effects were initially thought to be related to the caffeine content of green tea, the researchers found that the tea actually has properties that go beyond those that could be attributed to caffeine.

The same amount of caffeine as green tea, taken alone, did not affect energy expenditure in other studies. This led researchers to believe that there is some interaction with the active ingredients in green tea that promotes faster metabolism and fat oxidation.

Additional research has linked the metabolism-enhancing effect to a combination of caffeine and catechin , a type of flavonoid found in green tea. For example, a 2010 study published in the Journal of Physiological Behavior found that catechins can help break down excess fat, while catechins and caffeine can increase the amount of energy used by the body.

While this all sounds reassuring, it's important to put things in perspective. Even in studies that found weight loss among green tea drinkers, the rate of weight loss was quite small. In fact, if you drink sweetened green tea, the calories you add will outweigh the extra calories you can burn. …

Green tea and thyroid cancer

Green tea has been touted as having cancer-fighting properties, and some studies show that drinking it can reduce the risk of thyroid cancer.

In a meta-analysis published in the International Journal of Clinical and Experimental Medicine in 2015, scientists analyzed 14 studies with more than 100,000 subjects, nearly 3,000 of whom had thyroid cancer. Researchers have found a strong link between higher tea consumption and a lower risk of thyroid cancer.

However, it is not clear if the compounds in tea are the only reason for the reduced risk, or if the anticancer benefits are due to the fact that people who drink green tea may be more likely to lead healthier lives. usually. …

Side effects

Green tea is considered safe for thyroid patients. In this regard, it differs from some prescription obesity medications, as well as herbal products such as ephedra, which can increase heart rate and blood pressure, and are not recommended for people with thyroid disease .

However, there have been some studies that suggest that consuming large doses of green tea in extract form can have adverse effects on the thyroid gland by reducing blood T3 and T4 levels and significantly increasing TSH levels. However , it is important to note that this study was conducted in rodents, so the results may not necessarily apply to humans.

While drinking a cup or two of green tea a day is likely harmless, drinking green tea extract can be a different story. Several studies using green tea extract (which strongly concentrates the catechins found in green tea) have reported signs of liver damage. Taking green tea extract is a bad idea.

How-Tos Tea

There are no official guidelines on how to incorporate green tea into your diet. It is available in various forms, such as tea bags, bulk tea, additives, extracts, and iced tea. With the exception of additives and extracts (which can be toxic if overused), any of these forms of green tea will work.

Although green tea contains significantly less caffeine than coffee, it still contains between 30 and 40 mg per cup. Caffeine is known to interfere with the proper absorption of the common thyroid hormone replacement drug, levothyroxine. If you are taking this medicine, it is best to wait 30 minutes before drinking green tea.

Get the word of drug information

While green tea can have some metabolic-enhancing effects, it should only be taken in conjunction with standard weight loss programs and will not help you lose significant amounts of weight on your own.

Additionally, green tea extracts and additives, in particular, are not regulated by the FDA and can provide toxic levels of catechins. It's best to avoid these forms of green tea altogether.
