Specifically the section titled dietary protein intake on testosterone.
Notable quotes:
“A cross over design study used seven normal men from 23-43 years of age and compared a high protein diet to a high carbohydrate diet (15). This study has been referenced many times and cited as proof that high protein diets lower total T levels in the blood. The high carbohydrate diet from this study will be covered in Part II. The high protein diet consisted of 44% protein, 35% carbohydrate, and 21% fat and supplied between 2400 and 2500 kilocalories per day (kcals/d). Let?s assume it was an even 2450 kcals/d. The men also had bodyweights that ranged from 64-72 kg.”
…
While subjects followed the high protein diet, their total T levels were 28% lower than on the higher CHO diet (15)."

Your thoughts??
The s0-called “high” protein diet isn’t too different from the 40/40/20 that a lot of people recommend.
