I see what you're saying as advocating keeping people a little hungry so that they appreciate food more.

If it's a little hungry and not massive specieswide sex-drive mismatch the way we have now, then sure. You don't necessarily want to match the histograms - to eliminate the current bipolar orientation of human sexuality - just nudge them close enough together that the sexes aren't so frustrated with each other.

In my head I have an image of the parliament of volitional shadows of the human species, negotiating a la Nick Bostrom. The male shadows and the female shadows are pretty much agreed that (real) men need to be able to better read female minds; but since this is a satisfaction of a relatively more "female" desire - making men more what women wish they were - the male shadows ask in return that the sex-drive mismatch be handled more by increasing the female sex drive, and less by decreasing male desire...

Maybe it's just my mortal caution speaking, but whenever I envision tampering with human nature, I try to envision soft and subtle changes. At least to start with.
