Companies tout the benefits of slimming tea for weight loss, but health authorities don't recommend taking diet products. Whether slimming teas are consumed on an empty stomach or a full stomach, they likely won't help with weight management.
Slimming tea is unlikely to help with weight loss, and it may contain ingredients that pose a health hazard.
Green Tea for Weight Loss?
Some slimming teas contain green tea, which is known for the multiple health benefits it confers. However, research shows that green tea has little, if any, effect on weight loss. A May 2014 study published in the Canadian Pharmacists Journal said that green tea is one of the most common ingredients in weight loss products in Canada. After reviewing randomized controlled trials that explored the effect of the tea on weight, the study found any weight loss associated with the beverage wasn't large enough to be significant.

People interested in trying green tea could certainly drink several cups per day. The National Center for Integrative and Complementary Health says that drinking moderate amounts of the beverage is safe. Except for decaffeinated green tea, it contains caffeine, which can cause nervousness and interfere with sleep. The tea may impart various wellness advantages, but it won't produce a noticeable effect on weight.
While green tea consumption is considered safe, green tea extract is linked to several adverse effects, reports the National Institutes of Health. These include abdominal discomfort, nausea, increased blood pressure, constipation and liver damage.
No Benefit of Slimming Tea
There are many weight loss teas on the market, including China Slim Tea and Closemyer Slimming Green Tea, both of which contain the bowel stimulant senna. According to Truth in Advertising, weight loss teas are often based on senna, an herb with a laxative effect.

Cornell University says laxatives flush wastes from the intestines, but they don't flush calories from the body. Laxatives like senna cause several adverse effects, including dehydration and electrolyte imbalances. Senna can also lead to constipation, because it causes the intestine to become ineffective at moving stools.
It's best to steer clear of slimming teas and other weight loss products, advises the National Institute of Health. Their ingredients often haven't been studied for safety and efficacy.
The Federal Trade Commission states that the claims made by such products are often inflated, and they can have dangerous side effects. Before taking a slimming tea or similar product, it's best to consult your health care practitioner.
Alternatives to Slimming Teas
Weight loss teas and pills sometimes claim to boost metabolism, which manufacturers say leads to easy weight loss. The Mayo Clinic notes that the products have little, or no, benefit, and they aren't safe. Instead of resorting to a tea, adopt dietary and exercise habits that will lead to healthful weight management.
Rather than eating processed food that is high in sugar and low in nutrients, center your diet around fruits, vegetables, whole grains, healthy fats and lean protein. Limit saturated and trans fat consumption, and watch your portion sizes.
Harvard Health advocates adopting an 80/20 rule. This involves eating in a sensible, healthy way 80 percent of the time, but allowing occasional indulgences to prevent feelings of deprivation.
Exercise helps burn calories, and any amount is better than none at all. Start exercising slowly, and gradually include both aerobic exercise and strength training into your workout routine, recommend doctors at the Mayo Clinic.
