But what exactly about that situation makes it worse? Let's assume for a moment that a therapy exists that is funtionally identical to proper diet. It seems that each person could choose to weigh the costs of the drug vs. the increased enjoyment of eating whatever, or vs. the decreased time spent at a gym. The way things work today, you're right. People "should eat less". It used to be that if you didn't want children, then you shouldn't have sex. Thankfully we have a wide variety of options that allow us to decouple sex from reproduction. I don't see why we shouldn't also have options to decouple eating from getting fat.
