Solution to regulating hormones on long term keto?
 
Ran multiple variations of ketogenic diets over the last 7 years (CKD/TKD/SKD) with phenomenal results and I have always noticed a decrease in both testosterone and libido. I'm aware libido is not necessarily directly related to testosterone.

LCHF diets have shown to increase SHBG while lowering testosterone over the long run.

My personal experience with CKD, 1-3 days of high carb refers do not seem to resolve the issue.

Additionally, I'm also extremely concerned with damaging thyroid glad on long term keto... Maybe I am coming to the sad conclusion that ketogenic diets are just not sustainable year round.... :mad:

So you got blood tests before and during to confirm that testosterone dropped? Or is there some reason aside from libido that you believe testosterone went down?

Is there a valid reason you think a ketogenic diet is going to destroy your thyroid?

No blood tests; although, I feel all of the symptoms of low T and long term studies I've seen on LCHF diets have lowered T levels. I understand libido and T aren't necessarily correlated, but libido also tanks while I'm in Ketosis.

It's confirmed T3 drops in ketogenic / low carb dieting (I know these studies are all done at a caloric deficit -- would be neat to see them done at maintenance calorie level). I assume this lowering of T3 is normal and, maybe, this is "OK" due to the muscle sparing affect of low T3?

However, me being overcautious, I'm concerned with any long term altering of my thyroid (lowering T3), regardless of if it's considered "protective" or not.

I've also read that lower T3 is actually linked to longevity... Maybe I am sticking my head in too many "mainstream" articles on the Low T and Thyroid issue and have answered my own questions :D:D

Don't do a ketogenic diet forever?

Thanks for the reply. Coming to the sad conclusion it's just not sustainable long term.

Didnt wanna waste space for a new topic but something I wondered...i felt very mentally stable and calm doing skd and tkd, but eventually gym performance is meh. Oh highee carbs my performance rocks but hunger isnt as well regulated and concentration and mood isnt as good. How to balance this? Isocaloric setup ala Duchaine? Moderate carbs on training days and lower rest? Pick what's more important priority?

I really feel an isocalorie setup is best for mood stability, appetite control, etc. Carb cycling and ketogenic diets have always messed with my mood. They give better recomposition results, but in the end for me, they're usually not worth it. Everyone's different though. Maybe I'm just a complainer.

Yeah that has been my experience as well. Gonna lower my carbs and up fats for a while see how that goes then. I usually dont end up 33.3 across the board but close enough i guess (28 to 40ish depending on food choices that day for any given macro)

Don't do keto?

Seriously, how difficult is this solution?

I don't like this aspect of keto
So don't do it.

And you cannot damage the thyroid gland on the diet. The issue with T3 is cconversion in the liver.

Since I follow a CKD with weekly or bi-weekly carb ups (and have been for decades) I have not experienced any of these negatives.

It always comes down to the carbs....
