Losing fat, particularly in the abdomen, can be a challenging process that often requires significant changes in diet and exercise habits. Although some foods and beverages, such as green tea, may help speed this process by boosting metabolism, they are unlikely to cause a significant loss in belly fat when used alone.
Green Tea and Metabolism
Green tea has many compounds, including caffeine and polyphenols that affect the body in a number of ways. These different chemical compounds may be able to boost your metabolism, helping to speed up the rate at which your body burns calories and contributing to weight loss. An article published in "The American Journal of Clinical Nutrition" in 1999 found that an extract made from green tea increased metabolism by up to 4 percent. This suggests that green tea may be able to help increase the loss of belly fat, but it will be more effective if you use green tea as part of an overall change in diet and exercise.
