I think it's more subtle than this in the case of dieting though. Is there even such a thing as a diet that can actually work for everyone? I think there's certain axioms one has to accept when it comes to weight loss. First of which is to lose weight, you will feel hungry. There is no diet that can avoid this. Billions of years of evolution have worked to ensure that we feel hungry when we're losing weight. Diets fail because humans are supposed to feel hungry when they're dieting. No matter what the constraints of the diet are, no matter how much they advertise "you can feel satisfied as long you stick with foods X, Y, and Z", your body cannot be tricked into thinking it's satiated when it's not. At some point, trying to think of this from an engineering standpoint breaks down, because you're solving an intractable problem. Humans really are the issue here. I think we need to redefine diets as not a list of foods to eat or rules to follow, but instead a state of mind you have to have. An acceptance that you'll feel hungry, but it's worth it to be healthy or look good. It's actually kind of obvious when you think about it.
