Interesting point, though I do think people tend to do it the hard way. By that, I mean that most people have probably tried some form of extreme calorie deficit diet, which typically doesn't work in the long run. It's exceptionally hard to conform to these for any period of time. Even if it's successful once or twice, I suspect people will have a negative perception of the experience, perhaps feeding a bit into denial in the future. I'm advocating a much slower approach, based on a little bit of knowledge about what you're eating, plus some convenience tricks like swapping out your heavy staple meals for something a bit healthier (that's still easy to make). My guess is that most people want to see rapid, drastic changes, and are demotivated when that doesn't happen (or takes too much effort), hence the failure.
