I never heard of it, but it does not work, unless you tighten it so
much that you cannot eat as much as you used to.

I know a few people who say they work.  But everyone of them says you have
to wear them really really regularly and for an awfully long time each
session - plus not mind twitching the whole time you are wearing it!  Far
quicker and more effective to do a few crunches!
