Changing what you eat can boost your performance in bed

It’s no secret that the unhealthy American diet is contributing to an epidemic of obesity. But there’s another hidden epidemic that our fatty diets are at the root of: a national sex crisis.

One of the big culprits, for both men and women, is obesity. As a person's weight soars, their libido plummets due to biochemical changes that result in diminished bloodflow—there's simply no sex without strong bloodflow. And even when Americans do manage to have sex, the extra weight they're bringing to the bedroom also hinders their ability to have children—with men, it's damaged sperm; with women, it's ovulation problems.
