In many parts of the world, obesity has become a greater public-health crisis than hunger. Nearly every region has seen dramatic increases in obesity rates over the past few decades. The epidemic is especially prevalent in wealthier countries, though their poorest citizens tend to be the most affected. While this is by and large true in the U.S., sorting by demographic group reveals complex and surprising patterns. When it comes to how income affects weight—and how weight affects income—men and women generally experience inverse effects.
