Black tea
Fans of chai, English breakfast tea, and Earl Grey (all types of black tea) will be pleased to know that research has linked black tea to weight loss and reduced visceral fat.
A 2016 report published in the journal Molecules says that the polyphenols found in black tea have anti-obesity properties and can help with the reduction of body weight and visceral fat, while the animal study mentioned earlier from The Journal of Nutrition includes black tea alongside oolong and green for its effect on abdominal fat.
Participants from a 2014 study published in Food & Function who drank three cups of black tea every day for three months saw more weight loss and reduction in their waist circumference (AKA their belly fat) than those who didn't drink the tea.
