The keto diet may have both positive and negative effects on testosterone levels.

The positive impact lies in the fact that following the keto diet can lower insulin levels, which may contribute to improved insulin sensitivity and reduced inflammation. This, in turn, may help increase testosterone levels.

However, improper adherence to the keto diet, without an adequate intake of vegetables and greens, may lead to insufficient carbohydrate consumption, which in turn can result in decreased testosterone levels.
