Hi jskdean76,
As the previous post mentioned, I haven't heard of anything like this either, but let me warn you of these types of marketing tools! Please DO NOT spend your hard-earned money on something that will not promote long-term weight loss or a healthy life-style. It is a tactic, and only that. You do not need a tool to help you lose excess water...with exercise you'll lose the sweat that you need to in order to keep your body cool, etc.
I could go on and on, but just know it is a waste of money. Stick to regular, safe exercise and eating a healthy diet. You don't need a exercise belt!
Yours in health,
Kelli
