Lowfat diets drive T into the ground:
Low-fat high-fiber diet decreased serum and urine androgens in men.
I can't find the damn studies, but there were a number of Authors who doubled or Tripled their Natural Testosterone levels (and posted bloodwirk) by changing their diet
Triple Your Testosterone Cheat Sheet by Tim Ferriss
Edit: Here we go, Evidence-based recommendations for natural bodybuilding contest preparation: nutrition and supplementation
>Reductions in the percentage of dietary fat in isocaloric diets from approximately 40% to 20% has resulted in modest, but significant, reductions in testosterone levels [53, 54]. However, distinguishing the effects of reducing total dietary fat on hormonal levels from changes in caloric intake and percentages of saturated and unsaturated fatty acids in the diet is difficult [51, 52, 55]. In a study by Volek et al. [51], correlations were found between testosterone levels, macronutrient ratios, types of lipids, and total dietary fat, illustrating a complex interaction of variables. In a similar study of resistance trained males, correlations were found between testosterone, protein, fat and saturated fat which lead the researchers to conclude that diets too low in fat or too high in protein might impair the hormonal response to training [52]
>Competing bodybuilders must make an obligatory caloric reduction. If a reduction in fat is utilized, it may be possible to attenuate a drop in testosterone by maintaining adequate consumption of saturated fat [5]."
Study that decreased dietary fat ended up decreasing Testosterone:
Diet and serum sex hormones in healthy men.
"The possible effect of dietary fat content and the ratio of polyunsaturated to saturated fatty acids (P/S-ratio) on serum sex hormones was studied in 30 healthy male volunteers. The customary diet of the subjects, which supplied 40% of energy as fat (mainly from animal sources, P/S-ratio 0.15) was replaced for a 6 weeks period by a practically isocaloric experimental diet containing significantly less fat (25% of energy) with a higher P/S-ratio (1.22) and other environmental factors were stabilized."
But I mean you can get up to ~700ng/dl through diet alone. You can get up to ~1000ng through diet, training and lifestyle.
