The Minnesota Starvation Experiment was such a poorly designed diet that it's not really relevant to the modern discussion of prevent obesity among a relatively prosperous population. According to Wikipedia (https://en.wikipedia.org/wiki/Minnesota_Starvation_Experimen...), the diet was based on "foods that were expected to typify the diets of people in Europe during the latter stages of the war: potatoes, rutabagas, turnips, bread and macaroni." In other words, almost entirely carbs, with practically no fat or protein. Almost every reasonable diet I know of (coming from the modern fitness community at least) focuses first on maintaining adequate protein intake as the top priority, usually followed by at least a reasonable amount of fat. While it may have been useful to understanding starvation in a population with food scarcity, it just doesn't apply when looking at obesity in modern America.
