Anabolic Diet Effects on Testosterone?

One of the claims I hear constantly with diets like AD that emphasize low carb-high fat-high protein is that it increases the production of hormones like Testosterone. Now I’m not disputing this, and I understand the basic reasoning behind it, but what I’m asking is does anyone have a study or can prove to me that high fat/low carb diets cause a significant increase in T levels?

By significant, I mean an noticeable increase that would reasonably have an effect on strength/mass gain.

Why does everyone around here want people to go find studies for them. How bout you let us know what you find. Good or bad.
