Lady, if someone invented that they'd be a billionaire and it would be no secret

Even the sugar-free "chocolates" made for diabetics has calories.

If she's truly worried about it, she shouldn't be eating chocolate!

However, super dark chocolate (70% or darker) is actually good for you, but once you turn it into a truffle or something like that that the store the OP works at specializes in, it's not got the same properties as just eating 1/2-1 oz of the plain dark stuff does, due to the addition of the filling.

The closest she would get is Carob - my grandad used to eat the stuff a lot, since it is a recommended alternative for diabetics due to its very low sugar and fat levels.

I've head carob ice cream bars, that stuff is surprisingly good.
