Having a poor diet that is high in ultra-processed foods, sugars, unhealthy fats, and low in nutrients can not only cause obesity, but also metabolic disorders and reproductive issues in men.
According to a 2014 study, obesity in men leads to lower total and free testosterone. This also increases aromatase activity in fat tissue that converts testosterone to estrogens, disturbing the hormonal balance and lowering testosterone further.
In the long run, all of this can lower one’s libido and damage sperm production and quality.
