For centuries, green tea has been hailed as a weight loss solution, from ancient China to modern diet trends. Recently, TikTok videos have gone viral, claiming that green tea can act as “nature’s Ozempic,” helping to shed pounds. But does the science support these claims?

The Science Behind Green Tea and GLP-1

Many TikTok users suggest green tea increases the production of GLP-1, a hormone that helps regulate hunger and insulin levels. Medications like Ozempic work by mimicking GLP-1 to reduce appetite and cravings. While some studies on animals suggest green tea might have a similar effect, human research has been inconclusive. Experts like Dr. Jyotsna Ghosh from Johns Hopkins University argue that any impact green tea might have on GLP-1 is likely minimal and temporary.

Caffeine, Antioxidants, and Weight Loss

Green tea contains caffeine, which can slightly boost metabolism, and polyphenols, antioxidants that may improve metabolism and reduce fat absorption. However, studies on green tea’s weight loss effects have produced mixed results. While some people may lose a few pounds, it’s not comparable to the effects of drugs like Ozempic, says Rob van Dam, a professor of nutrition sciences.

The Bigger Picture in Weight Loss

Experts caution against relying solely on green tea for weight loss. Julia Zumpano, a dietitian from Cleveland Clinic, stresses the importance of considering broader lifestyle factors such as diet, exercise, stress, and sleep quality when aiming for weight loss.

While green tea may offer some benefits, its impact on weight loss is likely to be small. For those seeking significant results, experts recommend focusing on lifestyle changes rather than any single food or drink.
