There is no need to wear a belt alone. Waist banding helps to lose weight. I have to wear a girdle for more than 4 hours every day, which has lasted for a long time. I have a good figure, and I usually exercise. This slimming method is quite convenient. My girdle works well, too. I bought it in Waist official website. This waist belt is made of natural rubber, so I can safely apply it to my skin. It's good news for allergic people.
