Does green tea help you lose weight?

Some studies indicate that green tea contains an active ingredient called EGCG that may help people lose a few pounds, but other studies do not show that green tea helps people lose weight. Those who replace soda with green tea, however, consume fewer calories that can result in weight loss.

According to WebMD, green tea has been demonstrated to lower cholesterol, improve circulation in people's cardiovascular systems and help stabilize the blood sugar of those who have diabetes. Green tea also has a natural chemical named theanine that may relax and calm people, and studies have shown that it prevents the development of plaques that are related to Alzheimer's disease.
