Fitness and metabolic health are the keys to good sex because they provide physical and mental benefits.

Metabolically fit men can control blood flow to the penis that gives them erections on demand, staying power for prolonged, wild sex and hormone regulation that maximizes desire, instills confidence, but maintains control.

A study of young men (aged 20-45) showed that obesity increased the risk of erectile dysfunction (ED) by a high percent.

Obesity was defined as a body mass index of 30 or more (BMI is a measure of the proportion of height to weight). Surprisingly, ED was more prevalent in obese non-smokers than smokers. Obesity was not related to premature ejaculation, retarded ejaculation or problems with sexual desire (libido).

Abdominal obesity is an important sign of poor metabolic health and sexual dysfunction. Men who have big guts often have insulin resistance, which is a sure sign of poor blood flow control to the penis, reduced testosterone levels, poor physical fitness and a host of health problems that increase the risk of heart attack, stroke and some types of cancer.

Diet and exercise are the keys to reducing abdominal fat, improving metabolic health and boosting sexual performance.
