The Association between Popular Diets and Serum Testosterone among Men in the United States

Purpose: We examined the relationship of the serum testosterone level to low fat, Mediterranean and low carbohydrate diets in a large, nationally representative patient sample

Conclusions: Men adhering to low fat diets had lower serum testosterone levels even when controlling for comorbidities, age, body mass index and activity levels. As differences in serum testosterone between the diets were modest, the avoidance of fat restrictive diets should be weighed against the potential benefits on an individual basis
