As well as burning fat, the super-tea could also aid weight loss by balancing out your blood sugar.
“We need sugars; they’re part of our metabolism, but excess sugar means the spike in blood glucose triggers insulin production which helps shunt the sugars off to be stored,” said Dr Bond.
“An indication in how resistance the body is to insulin and insulin spikes, is fasting blood glucose.”
In a recent study by the Tea Advisory Panel, fasting blood glucose was more stable in those that drank rooibos.
Plus, rooibos is rich in antioxidants including aspalathin, which may help to reduce the risk of developing diabetes for the same reason.
