Live Like a Caveman for Better Sex
Human metabolism reflects millions of years of evolution. Over time, human genes adapted to thrive on the caveman diet and whole-body physical activity. Our genes, however, are not prepared for a sedentary lifestyle or the modern diet, which increase the risk of poor sexual performance, obesity, and degenerative diseases.
Food and exercise are critical to survival, but physical inactivity and poor diet can result in sluggish metabolism, bad sex, and chronic disease. Human diets have changed during the past 10,000 years from a caveman diet that was high in fruits, vegetables, nuts, lean grass-fed meats, and seafood to a modern diet that is high in calorie-dense, low-fiber processed foods high in salt and saturated fats. We have substituted whole-body physical activity of the caveman for a sedentary lifestyle centered on television and the Internet. We are genetically programmed to thrive on the caveman diet and whole-body physical activity.
Sexual problems, such as erectile dysfunction (ED), poor sex drive, and lack of energy for sex, are surprisingly common in 20-, 30-, and 40-something-year-old men. It accounts for the mega sales of erection-boosting drugs like Viagra and Cialis. What most guys don’t understand is that following the caveman lifestyle can do more for their sex lives than a boatload of erection-promoting pills. Americans want it easy: Why exercise and eat healthy foods if you can get the same results from a pill? Cure the cause of the problem— poor metabolic health— and you will improve sexual performance, achieve harder erections, and look better in bed. And, you won’t need drugs like Viagra that may have side effects.
German scientists found that exercise was as effective as Viagra for improving erection capacity in men with ED. Erection problems often stem from abnormalities in the cells lining the blood vessels. Healthy cells secrete more nitric oxide, which is important for delivering blood to the penis and other organs and tissues. Blood vessels of obese, out of shape men have a reduced capacity to release NO, control blood flow, and promote healthy erections. Excess abdominal fat, and heart disease risk factors such as high blood pressure, high blood cholesterol, and diabetes, are sure signs of poor metabolic health and impaired NO control.
Recent studies found that the caveman lifestyle improved metabolic health and reduced the risk of heart disease, insulin resistance, type 2 diabetes, high blood pressure, and obesity. However, the diet is low in vitamin D and calcium and high in fish, which often contains contaminants such as mercury. The modern equivalent of the caveman diet contains high fruits, vegetables, nuts, lean grass-fed meats, and seafood, but can be supplemented with nutrients that benefit the metabolism of modern humans. Including foods and supplements containing Omega-3 fatty acids, polyphenols, fiber, and plant sterols may improve sexual health and prevent heart disease, diabetes, and cancer.
Problems with sexual performance and fatigue have increased in American men at a time when obesity rates have sky rocketed. In the past five years, the number of obese and overweight people in some states has increased by more than 100 percent. That’s an astounding figure that can’t be blamed on our genes. We are eating too much and not getting enough exercise, which conflicts with genes controlling metabolism that developed over millions of years. Insulin resistance and abdominal fat are responsible for an epidemic of bad sex.
Excess gut fat is the kiss of death in the bedroom. High amounts of abdominal fat make you less attractive to women, but the problem is a lot more serious than that. Gut fat reduces blood testosterone levels, which decrease sex drive, the capacity for erections, energy levels, aggressiveness, and self-confidence. Too much fat is a triple-whammy threat: women find you less attractive, low testosterone destroys your game, and sexual performance goes down the drain. The caveman lifestyle enhances metabolic control, which decreases abdominal fat deposition, reduces insulin resistance, and improves the capacity for erections.
Adequate testosterone levels are important for optimal sexual performance and abdominal fat control. Scientists from Norway and the University of California, San Diego— led by Johan Svartberg— found that men with higher waist sizes had lower levels of testosterone. Men with waist circumferences greater than 40 inches had 30 percent lower testosterone levels than men with waists less than 37 inches. Large waist size depressed testosterone most in men 25 to 50 years old— the time they are most sexually active. Dr. E.C. Tsai and co-workers from the University of Washington School of Medicine— in a seven-and-a-half-year study of body fat and sugar metabolism in Japanese-American men— found that those with the lowest testosterone levels gained the most abdominal fat.
Low testosterone impairs metabolic health, promotes obesity, and decreases sexual performance. Testosterone has important effects on sex drive and sexual performance. The hormone contributes to sperm cell production and semen volume, sex drive, and the capacity for erections. Overweight, inactive men often have decreased sex drives and difficulty getting or maintaining erections. These sexual problems can begin as early as the mid-20s. The combination of whole-body physical activity and the caveman diet help minimize abdominal fat deposition and boost sexual performance.
