The new co-host of Iron Culture, Eric Trexler, is back with another (monster) episode. In this episode we take a look at everyone's favorite hormone, testosterone.
Specially, Dr. Trexler examines the role of maconutrient changes on testosterone levels. How does fat & carbohydrate intake impact a person's testosterone?
We also explore body composition differences and how this can have an even larger impact on one's testosterone. Lastly after sharing the not so pleasant realities of dieting and experiencing low testosterone symptoms, Eric shares key points for maintaining a healthy level of testosterone.
