Consumption of any food in excess leads to weight gain, which is the number one sex drive killer for any man, according to Corey B. Schuler, functional medicine nutritionist at the Metabolic Treatment Center. “The worst food that a man can have for his sex drive is too much of it,” he says.
“Diet accelerates the aging process. Anyone carrying extra weight from ages 35 to 60 is accelerating the aging process—anyone living a high stress, poor diet and no exercise lifestyle. Midsection increase is probably the number one reason for lost sex drive.” A good diet equals good sex. “People ask if there’s some magic to it, but it’s nothing like that,” says Yarian. “The better the person’s diet is, the more healthy their sex drive.”
But the fact is that the more that I look at this situation (swear to God or not), it is BS. No reference to physician testing. No mention of Lab results (the only way that you know what your TT or FT or SHBG or Prolactin or Estrogen levels are… which a physician would insist on knowing all of those). No mention of a physician doing initial testing to see what your LH and FSH levels were to see if you were primary hypogonadal or secondary hypogonadal (one of the causes for a young man past puberty start to be hypogonadal is a tumor on your pituitary gland… it is THAT serious – and isn’t caused by generic stress; long-term stress in the range of PTSD type stress could cause it in some cases).
9. CAUTION: Chasteberry (Vitex agnus castus) . Chasteberry has been shown in several in vitro studies to bind to dopamine receptors in pituitary cells.  It also has a history of being used in women for hyperprolactinemia.  Unfortunately, there appear to be no studies on men and, at least in women, it has some unusual affects such as increasing progesterone and LH (leutinizing hormone) while decreasing FSH (follicle stimulating hormone). In my opinion, this seems like an unpredictable mix of effects for long term usage.
