I'm not sure I follow, especially the focus on overweight women not marrying up. The article has a more egalitarian slant to it than that.

These things can be true, but what is their relation to a disrupted dating market?

If you are at the bottom of the dating hierarchy (for whatever reason) as a male in the USA, you are typically limited to overweight women. The gulf between real and fake sex thus becomes much larger, and fake sex more appealing, than in a society without obesity.
