Oolong tea
Another tea that has been proven to help with abdominal fat is oolong tea.
Oolong tea comes from the same leaves where you'd find green and black tea, but it's partially oxidized, whereas green tea is unoxidized, and black tea goes through full oxidation. Oolong is made by drying the leaves under the sun until they're wilted and curled up.
Research shows that oolong tea also contains polyphenols linked to faster metabolism and reduced abdominal fat. One animal study published in The Journal of Nutrition showed that the polyphenols in green, black, and oolong teas all had the ability to help lower visceral fat tissue.
One 2020 study from the University of Tsukuba even found that oolong tea increased the breakdown of fat by around 20%, and continued to do so while participants slept.
