Why would you think that there are such choices? The obesity epidemic did not come about out of a desire to avoid famine. It came about because the American Heart Association took flimsy scientific evidence that high levels of saturated fat in the diet increased risk of heart disease and then sought to reduce the American intake of saturated fat. They succeeded. They successfully reduced the percent of the average Americans dietary calories which came from saturated fat by 15% which was their goal. Unfortunately, removing saturated fat from foods makes them taste like cardboard. So to combat that, food makers added salt and sugar to restore some flavor. As a result, the total amount of calories consumed on average ballooned, diabetes became an epidemic, and even the heart disease they were intending to avoid through their efforts reached all-time high levels along with a host of other health problems. No one was starving, and famine wasn't the alternative. The alternative was educating the public and leaving them with the choice, a situation which is less totally effective but more flexible and seemingly less prone to large scale unintended consequences. I won't get into genocides in too much detail, but the concentration camps were an outgrowth of eugenics, an attempt to improve human health and well-being through "scientific" engineering of the gene pool. It was based, however, upon fundamentally incorrect ideas about how genetics and evolution work, flaws which were known at the time but which were ignored because the idea of rounding up anyone not liked and wiping them out was apparently too alluring for them to step back and say 'we don't have sufficient evidence this would even work'.
