Erections are a hydraulic event. Keto improves cardiovascular risk factors: lowers triglycerides, raises HDL, and reduces blood pressure. Better heart health = harder erections. However, there is a catch: a very low-carb diet may reduce arginine (an amino acid needed for NO production) if you avoid nuts and seeds. Eat pumpkin seeds, macadamia nuts, and dark chocolate (85%+ cacao).
One of the most common complaints is an initial drop in libido. When a person first starts the keto diet, the body goes through a period of carb withdrawal, often leading to the "keto flu," which can involve headaches, fatigue, nausea, and dizziness. Experiencing these physical stressors can make anyone feel less interested in sex. However, this is typically a short-term phase. Many who persist report a marked improvement after their bodies adjust. http www keto sex
