Testosterone, responsible for turning boys into men.
Testosterone is a steroid hormone, from the androgen group. In humans it’s secreted in the testes of the male and ovaries of females. Small amounts of testosterone are also secreted by the adrenal glands.
In men it plays a key role in health and well being. On average an adult male produces 40 to 60 times more testosterone than an adult female. In men it’s responsible for everything that makes us a man. Increased libido, facial hair, chest hair, increase in height, growth of the adams apple, jaw, chin, nose, shoulders, bone density and muscle.
In females, when the ovaries shut down at menopause, the amount of testosterone they produce is reduced by half, resulting, for many women, in diminished sexual desire, flatness of mood, dry skin and decreased mental sharpness.
Looking over this we can see it plays a big role in our lives whether male or female. Wait a second that last one there for men caught my eye, muscle growth. Yep it increases lean muscle mass. You can see why we might want to maximize our testosterone then.
Natural factors we can control that affect testosterone levels include
- Sleep
- Weight training
- Getting enough fat
- Zinc
Okay so getting enough sleep, that’s important and easy enough. Weight training, if you’re reading here chances are you’re already doing that. However if you don’t have the 3 core exercises: Squat, Deadlift and Bench press in your routine you may want to consider it. These three exercises have been shown to increase total testosterone levels much more than any other exercise.
Getting enough fat again isn’t something most of us are deficient in, a whole egg in the morning, flax oil or some olives is all it takes.
How about zinc? Well eating excess amounts of zinc isn’t going to boost your testosterone levels to new heights unfortunately. But making sure you’re not deficient could have a huge impact. 11mg/a day is our target for zinc intake with our upper tolerable level being 40mg/day. Let’s focus on some quality sources of zinc:
- Poultry – a chicken breast will provide about 10 percent of our daily intake.
- Red meat – beef can provide about 25-60 percent depending on the cut.
- Milk – a cup of milk has about 6 percent.
- Beans – provide about 8 percent per half cup.
- Bread – provides about 10 percent per slice.
- Egg Yolks – provide about 3 percent per egg.
Zinc, from plant sources is minimal and harder for your body to absorb. So after looking at these foods, do you get enough zinc in your diet? If not it might be worth considering supplementing with an additional 5mg a day.
If you‘ve been reading a lot about testosterone you might be saying well what about cholesterol? That affects testosterone levels. Well I’m here to argue that eating more or less cholesterol will not have an effect on your testosterone levels because the liver is able to produce more if you don’t eat it. And the liver will produce less if you do eat more. However not taking in enough fats can lead to a deficiency.
