Reduce insulin resistance to lower DHT
Berg explains that finasteride only blocks the enzyme, but the real problem is metabolic. He details that insulin resistance stems from excessive carbohydrate consumption, frequent eating, and processed foods. By adopting a lower-carb, less frequent eating pattern, the body can restore insulin sensitivity, thereby reducing the hormonal cascade that leads to elevated DHT. He also notes that stress, liver issues, and zinc deficiency contribute, but diet is the primary lever. This approach, he implies, could make drugs unnecessary for many men.
High insulin levels stimulate androgen production, increasing the substrate (testosterone) available for conversion to DHT by 5-alpha reductase. Lowering insulin through diet reduces this drive, normalizing DHT levels.
The number one reason why your DHT is too high is because you have insulin resistance.
