In terms of properties, black tea and red tea also work the same way as green tea in terms of helping you lose weight. They all act as a diuretic which helps prevent bloating. They all contain powerful antioxidants which help flush off toxins and revive the body’s metabolism. And they all can combat excess fat. So what is the difference? Why is the Green Tea Weight Loss method getting more attention? The difference is with the potency. It is believed that green tea contains more antioxidants than other types of tea. As a result, it is more effective in inducing a faster weight loss. At first though, it may not seem that way because green tea looks lighter in color.
