One of the biggest money-making industries in the world is built on people's hope that they will somehow magically lose weight without doing anything differently. Every week, there's a new diet system or a new approach and consumers jump all over it.
I mean, look, we all know how it works: eat less and get more exercise. EVERYBODY knows this. But because carrying it out would take discipline and commitment, they keep looking for a shortcut or an easier way that gets them washboard abs while they live like couch potatoes.
They rely on hope. They hope they can eat half a gallon of ice cream and still wake up three pounds lighter in the morning. They hope they can watch Seinfeld reruns instead of working out and somehow that beer gut will just disappear.
