Maximilian Gotzler's presentation discusses an experiment focused on the impact of diet on testosterone levels, noting that while his biomarkers were normal, they were not optimal, particularly with low testosterone and vitamin D. He outlines a high-fat, low-carb diet combined with lifestyle factors such as sleep and stress management, which affected his testosterone levels, leading to fluctuating results. Ultimately, while he experienced mood improvements with increased testosterone, he humorously concludes that it did not transform him into 'Wolverine.'
