I am one who does not place a lot of faith in “reduced carb” diets affecting SHBG. My SHBG was high when I ate a normal diet; and is still high on a reduced carb diet. I don’t eat breakfast either - and NEVER have. But, as part of my attempts to reduce my SHBG, I now eat a protein bar (NOT energy bar) every morning as “breakfast”. Has it helped? No. But I have grown used to it, and I figure the extra protein can’t hurt.
My thread is here:
My experience is limited, and anything I say is ONLY based on what I have seen in my situation. It may or may not apply to anyone else. I have had average-to-high LH & crazy-high-FSH all along because my testicles were working overtime to produce enough T to satiate the SHBG (which it was incapable of doing). Once you start TRT, they both drop to (virtual) zero.
I am still a guinea pig trying to work through the high SHBG … and continue to try new things.
Good luck.
