Increase Testosterone With the Right Fats
The more fat you eat, the more testosterone you produce. This is a basic and irrefutable fact of human physiology. Of course, if you dine on whale blubber all day long, or the fat-calorie equivalent, you'll soon get fat yourself, which will negate all those testosterone-increasing effects.
Body fat is the main repository of aromatase, the enzyme that converts testosterone into estrogen. So, lots of body fat, lots of aromatase; lots of aromatase, not much testosterone. You can't go hog-wild on eating fat, but the fat you do consume should be chosen wisely, as some fats raise testosterone a lot more than others.
Scientists at the Instituto de Investigaciones Bioquimicas de La Plato tested the effects of four dietary fats on male rats. The rats were given soya oil, olive oil, coconut oil, or grapeseed oil (mixed in with their feed) for 60 days.
Olive oil and coconut oil led to increased production of testosterone in the rats, along with heavier testicles. Soya oil and grapeseed oil were a complete bust, leading to neither significantly increased testosterone nor heavier nuts.
By the way, don't discount this study because it was done on wee beasties. Here's why.
It works because the Leydig cells in the testicles convert cholesterol into testosterone. Eating a lot of coconut oil or olive oil helps the Leydig cells absorb more cholesterol.
Furthermore, olive oil and coconut oil increase the activity of an enzyme involved in the production of testosterone.
If you want to increase testosterone levels, make coconut oil or olive oil your main source(s) of fat. Cook with either of these oils, add them to your protein shakes, drizzle olive oil over your cooked vegetables, add coconut oil to your coffee, or even eat a tablespoon of either in-between meals. In addition to allowing you to produce more testosterone, it'll also help quell hunger.
Likewise, make sure you're getting enough omega-3 fatty acids, which can also optimize testosterone levels and lead to better reproductive health. More info here.
