It is simply because you are not looking far enough. Yes, it is easier to get obese now. Imagine a world centuries ago, in the hunter-gatherer times. It was very hard to get obese then because it was a serious risk. Over time, technology has made it safer to get out of shape and obese. The alternative is they get cancer? Well, now more people might stay obese, perhaps just a small fraction, or people will be less motivated. Maybe it will be hard to calculate based on this one invention, but 100 inventions like this means more and more people will stop caring. Imagine a world where medicine has solved 100% of problems. Then you could just get obese very easily without much consequence. I am not assuming people who are overweight AREN'T aware. Of course they are, and some have a lot of difficulty losing weight. But some do, and now the incentive to do so is imperceptibly lessened.
