The last time I saw these products demonstrated the guest was being amazingly harsh, forcing the models to undo their garments live on air so as to show the before / after shots. The products did appear to make a difference. I don't believe in such products though. Who would want to be squashing all that flab in when you could just go down the gym / go running / swimming / cycling and have a super healthy diet and not have the flab in the first place.
