According to the Wu-Yi Source, this tea may diminish the fattening effects of carbs, reverse the signs of ageing, prevent plaque build-up and boost energy levels. Wu-Yi tea is a type of oolong tea that is thought to burn twice as much fat as green tea.

One study showed that by consuming oolong tea 15 minutes before eating carbs, the occurrence of insulin spikes was reduced. Wu-Yi should be consumed at breakfast and before or with the evening meal. While many people can expect to lose weight after 10 days, most results happen within 30 days. One box of Wu-Yi has 60 total servings.
