This just begs the next "why". Why are people eating more now?
Such a significant behavior change across a large population is not well explained by "we just did".
I'm not sure fast food consumption or huge portion sizes is a great explanation. If fast food is the problem, why does that matter if it just comes down to calories? As for larger portion sizes, would even larger portions make us continue eating? Would tiny portion sizes make us all deadly malnourished?
