On paper it looks simple to raise, in practice though, it's a much different story. Insulin inhibits Testosterone production; more-so it's the insulin resistance that is correlated with low T levels. Relationship between testosterone levels, insulin sensitivity, and mitochondrial function in men. - PubMed - NCBI
In other words, low T is a human caused issue, not an age related issue. As for what causes insulin resistance, the answers should be obvious: Diet, Eating frequency, Stress, Sleep
As for diet, foods that cause large insulin loads leading to insulin resistance over the long-term: Starches, sugars, processed foods. Eating frequency: Continually eating doesn't allow insulin levels to fall. Stress (Cortisol), this is obvious, stress suppresses Testosterone. Sleep (probably should have mentioned this first), is probably the biggest factor, don't sleep enough, Testosterone falls and insulin resistance ensues. Despite all factors; one can have a perfect insulin load diet, good eating frequency, zero stress, and still turn themselves insulin resistant with poor sleeping habits. All factors considered, unless sleep is normalized, adequate, restful, and follows the circadian rhythm, all attempts at raising Testosterone (except for TRT and roids), will be futile.
If you want to raise your Testosterone, it's best to go get a fasting insulin test first. It needs to be low, and by low I mean on the very low end of what doctors consider normal (or maybe even lower than that). Aside from sleep, all out fasting is the best way to lower fasting insulin levels. It's something like 71% more effective than diet at reducing insulin. Of course combining with diet will produce much quicker effects. With diet, you probably shouldn't be eating high carb, but nor should one be eating high fat either. If you think about it from ancestral terms, they didn't "fat bomb" any of their food. Removing any food that's processed removes all oils (including coconut and olive oil), butter, dairy and the like. You're basically left with a diet that is primarily meat based (red) including the internal organs, fruit occasionally as it's seasonal, and vegetables as a last resort, aka, not a significant source in their diet. The insulin load with that type of diet is quite low, and given the fact they'd have extended fasts in between animal kills for food. Diet wise, that is probably your best best at raising T levels.
Edit - I was listening to a strength coach the other day (Charles Poliquin), and take it for what it's worth, but from his observation, it wasn't necessarily high T levels that was correlated with benefits associated with Testosterone, its high levels of DHEA sulfate. He's witnessed benefits generally listed with high T levels in people with low T levels by high levels of DHEA sulfate. It's interesting when you think about it.
What you are saying is opposite of what Ray Peat talks about and i dont agree with most of it at all. sugars, starches etc does not cause insulin resistance. Insulin is very anabolic. Insulin lowers cortisol. You talk about fasting and all that, and yeah its just to much total opposite away from Ray that i cant respond to it.
