Catechins are the substance in green tea that are believed to aide in weight loss and fat burning. Green tea, black tea and oolong tea are all derived from the Camellia sinensis plant. The difference in the teas is in the processing. Green tea is made using the leaves in their unfermented state, while black and oolong tea are both fermented. In this unfermented state, green tea has a greater concentration of polyphenols and less caffeine than other teas. These polyphenols in green tea are primarily catechins, as well as five other types of catechin compounds that all help to support weight loss.
