This is one of my favorite topics, and I’ve discussed it in great detail several times on the Nutrition board.
The various ways of naturally boosting your body’s anabolic hormone levels primarily produce miniscule results by themselves, but if you employ enough of them, many little things lead to big things.
You’ve listed some good practices above.
I will simply add a bit to them.
limiting carbs for about 2 hours prior to bed to NOT hamper gh release.
Also avoid excessive fats before bed. Studies indicate that hGH secretion is greatest in an environment of low carbs, low fatty acids, and high amino acids.
I prefer to take either some BCAA’s and/or desiccated liver tablets just prior to bed.
You can also elevate growth hormone secretions by using higher rep schemes with shorter rest periods during your training.
Eating some red meat a few times a week
Do not underestimate the value of healthy fats - especially when cutting. Your gonadotropic hormones (testosterone) are cholesterol derivatives. Increasing healthy fats will have a positive effect on your sex hormone levels. Think egg yolks, red meat, olive oil, fish oil, CLA, etc.
Supplementing with zinc/zma
Many people believe they are getting sufficient levels of zinc through their food & multi-vitamin. However, don’t forget that intense training depletes those levels. Zinc is an excellent anti-aromatase, as is broccoli, spinach, and brussel sprouts.
According to Charles Poliquin, he tests every one of his athletes for zinc deficiencies, and almost every single one is deficient.
Getting 8 full hours of sleep a night.
Quality sleep is crucial for optimal hGH output. There are thousands of articles on improving sleep architecture - many of which, say the same things - so I won’t bother listing them here. It’s an easy Google search.
These are very brief outlines of effective principles.
A little searching will reveal greater details for those who are interested and put in the time.
I believe that through exercise and dietary manipulation, you can aid your anabolic hormone levels just as - or more - effectively as many OTC supplements that claim to work miracles.
