Darryl -- I don't disagree that healthy diets can be maintained on with a range of macronutrient ratios, including high carb. But you are factually incorrect when you assert that Americans ate more of everything (all the caloric increase was in simple carbohydrates), and that levels of physical exercise decreased (physical exercise increased.
