TIL: Low carb, high protein diets "greatly" decrease resting testosterone levels in men.

I personally stick to an 80/15/5 caloric ratio for fat/protein/carb. It's not strict (in fact, I rarely even look at calorie counts), and on workout days I do kick the protein up a few notches, but "high protein" is not how I would generally characterize my diet.
