This has failed though. Over 40% of Americans are obese. This costs us as a society hundreds of billions in healthcare costs, much of it federally subsidized.

Being obese is a simple choice now, one can choose to be fat or choose to take a once weekly shot and not be fat. Take Elon Musk, he is clearly overweight. Is your argument that he lacks self-discipline as a person and is as such a complete failure? Of course not, the man is clearly more disciplined and driven than most people. He just eats like crap as he has other priorities. I am open to you explaining the argument as to why 40% of people being obese so that they have to learn self discipline in just that single area of their life and all of the associated social, health and financial costs is more beneficial to society as a whole than people taking a shot and losing weight and gaining all of the benefits that being obese robs society of. Society evolves as its technology does. I'm sure its not the case but your argument appears to devolve to "Back in my day we didn't need a shot to be thin like you young kids, we walked up hill both ways to school with our little brother on our back. IN THE SNOW!"
