Diet and Commerce

I'm hungry. why? That's because I haven't eaten much food today. If so , why don't you just eat it? you might say. But I have something I have to do. It is a diet. For that I have to put up with some hunger. But starvation is hard. Very painful. That is why there are so much books on dieting in the world. And the same books sell many times over. The reason is simple. Because people fail to lose weight over and over again, and they try to lose weight over and over again. The challenger of people is an important lifeline in business. So many times, they'll help you lose weight and advertise the feast as often as they can.
