La Mar Reducing Soap
Our world has a long history of schemes that have promised to help you lose weight fast, without any exercise or changing your diet… or really doing anything at all. But notably, in the 1920s and ’30s, women bought lots of “La Mar Reducing Soap” and a bunch of other products that promised to wash your pounds away while taking a bath.
The truth? It was just hand soap, and no amount of scrubbing would make the fat fade away. If a product existed that could wash the fat right off of your body, it would probably still be around today.
