Ok here goes: I was 285lbs, diagnosed medically as having less Testosterone than a baby kitten. I think this was one of the things that got me seriously digging in studies and information in books and online until ultimately logic brought me kicking and screaming to whole natural foods.

To stimulate testosterone production, the hypothalamus releases a substance to the pituitary gland called gonadotropin-releasing hormone (GnRH). This hormone, in turn, causes the gland to produce two other hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), collectively known as gonadotropins. LH is released into the bloodstream where it travels to the male testes and triggers the production of testosterone from cholesterol. If this process continues until the testosterone level becomes too high, the pituitary slows the release of LH so production slows down. FSH is similarly involved in the increase and decrease in sperm production.
When LH reaches the testes, it influences activity in the Leydig cells, which are where cholesterol is gradually changed into a series of compounds until it becomes testosterone. When the small but vital amount of testosterone produced is released into the bloodstream, it is mostly bound to a special "carrier" compound called sex hormone binding globulin or SHBG. SHBG, which is produced by the liver, plays an important role in regulating the amount of "free" testosterone circulating in the body at any one time. The more SHBG there is the less unbound, active testosterone is able to move from the blood stream into cells where it is needed. As SHBG levels rise and fall, so do free testosterone levels, except in reverse.
There are 2 major parts to Increasing your Testosterone. Precursors(Lutenizing Hormone) and Anti-Estrogenics.(Block Conversion of Testosterone into Estrogen and block SHBG:sex hormone binding globulin)
Its all whole food, I do not condone supplements.
Zinc- luteinizing hormone AND anti-aromatase

- Wild Fish (best)
- Shellfish
Vitamins A, B, C, E - Testosterone Production
- Wild Meat!
- Avocado

- Wild Meat
- Eggs
- Liver
- Shellfish
Potassium
- Avocado
- Potatoes
- Sweet Potatoes
- Spinach
Sleep. Seriously. its when you produce the most Testosterone, and lower stress/more rest will inhibit estrogen conversion.
Sex. Seriously. More of it, or even thinking about it, boosts Test Production.
HIIT - High Intensity Workouts. Train Fasted, Train hard, if you're not breathing heavy and sweating afterwords, you did it wrong.
I dropped to 185lbs, then went on a heavy weight gaining regimen, have gained back 25lbs of muscle and can still see my abs. My testosterone is now well above average.
The beauty of it, other than a few veggie focuses, its a meat dominant paleo diet to the core.
