In this article I’d like to talk about testosterone from the viewpoint of its anti-aging effects. And how the lowering of testosterone levels in society, not just in the elderly, speeds up our biological aging.
Testosterone, like Growth Hormone, plays a large role in muscle bulk and strength, as well as fat-burning — in both men and women.
Known as the “male” hormone, we see much higher numbers in men than in women, though women still need this just as men still need some estrogen, the “female” hormone.
Normal testosterone levels give men that chiseled look, high energy levels, and strength.
In women, we also see more definition, muscle, and energy.
And it gives men and women smoother, firmer skin.
But the lower our testosterone levels get, the more fatigued we can feel, and it becomes harder to build muscle and lose fat. It also increases the risk of disease due to its role in conjunction with our immune system and healthy cellular responses.
And, due to its anti-aging effect, lowered levels of testosterone also increase wrinkles and sagging skin.
But, while most people think lowering testosterone levels has to do with aging — and it does — overall, this process is actually being sped up.
Testosterone levels, even in young men, have been dropping for decades now.
This isn’t “dropping as one gets older.” This is a man in his 30s today having lower average testosterone levels than a man in his 30s forty years ago.
In fact, overall levels have been dropping about 1% each year for the last 50 years at least… for all ages.
We see this most dramatically in sperm counts, which are down an average of 60% since 1970. This is why we have so many fertility clinics now. We didn’t need them before.
It’s gotten so bad that LabCorp, the largest medical testing company, lowered their standards for what are considered “normal” testosterone levels due to too many men no longer fitting into the earlier known healthy levels.
As they said in their release, this was: “… endorsed by a group of professional associations, government agencies, and commercial entities in 2010.”
So government and for-profit companies pushed for this. Strange place to get a nudge from on this subject.
And doctors were not happy with it, some outright attacking LabCorp on their own websites and blogs, and validly so. Testosterone is a vital hormone in our bodies, and the lower our levels are, the lower our levels of overall health will be, and the faster our biological age advances.
The idea to lower standards of what healthy testosterone levels are to fit the average man today, instead of raising the health levels of the average man to where their hormone levels are in actual normal ranges is, quite honestly, outrageous.
Instead of rolling up our sleeves and finding the cause of the problem… we’re just going to pretend that lower levels of health is actually normal?
No.
While there could others (your body is a complex organism), we do know many key points that absolutely lower testosterone levels and which, when prevented, can result in rising testosterone levels.
And almost all of them come from what is currently the Common Western Diet, which didn’t exist 40 or 50 years ago.
Sugar is an energy source. And natural sugars are just fine for the body.
But in today’s food we’ve grown so accustomed to the high number or sugars, processed sugars and other carbohydrates that we don’t realize just how much our sugar intake has grown.
It’s A LOT.
Our bodies certainly don’t need it. Though they sure are addicted to it. Just try ask most people to not eat even something ax simple as bread for a week. It will be hard for them. Most breads are almost completely sugars once inside the body, and our cells are addicted to them.
But high sugar levels bring on high cortisol levels and cortisol works on a seesaw with testosterone. When cortisol rises, testosterone lowers. And, unfortunately, the more testosterone lowers, the more cortisol rises and stays dominant, keeping testosterone levels low.
But this isn’t just from sugars. There are two essential fatty acids our cells need. One is Omega 6, which is used to make inflammatory signaling molecules, and the other is Omega 3, used to make anti-inflammatory signaling molecules.
As we know, with inflammation comes cortisol rising.
Our omega 6 to 3 ratios in our cells should be about 1 to 1.
But our foods today are incredibly high in omega 6 and very low in omega 3. This is in large part due to the vast use of corn and soy (both very high in omega 6) as the bases for almost all processed, packaged foods today.
We also see this in our meats. Cows fed corn and soy — not their natural diet — achieve ratios of about seventeen omega 6 to one omega 3, something they then pass on to us, while 100% grass-fed cows have a natural internal ratio.
This has gotten to the point where most people have an omega 6 to 3 ratio of 20:1 and even as high as 40:1.
This lifts cortisol significantly, lowering and keeping low our testosterone levels.
We also have foods so thoroughly processed that many are quite barren in real nutrition in the form of vitamins and minerals needed by the body to both manufacture testosterone, keep cortisol levels low, and properly utilize the testosterone.
And then there is the attack on cholesterol. Your body needs cholesterol to survive. As covered in this article, individuals with cholesterol levels in the low 200’s were actually found to live the longest.
Well, cholesterol is one of the main constituents of testosterone. Without it, your body can’t make testosterone, at least not in the quantities it needs.
Then there is the matter of toxins in our environment as covered earlier.
While there can be other cases, these are some of the largest culprits and points which, if handled, can significantly benefit our testosterone levels and overall health and longevity.
As far as what to do with this, beyond eating organic and grass-fed, staying away from processed foods and processed sugars, getting in your proteins levels and working out to trigger testosterone synthesis and use, I’ll cover that in the wrap up for this series as it all comes together.
But I hope this helps.

We know about amino acids, hormones, and how different foods affect our ability to build lean muscle, burn fat and stay healthy.
But if we want to achieve maximum levels of energy, recovery, health and performance, and build the most lean muscle, then we need to go down to the cellular level.
After all, our bodies are just one big mass of some 100 trillion cells all bonded together.
How well we're doing is an exact reflection of how well our cells are doing.
And they require a multitude of nutrients and biochemicals, all held in equilibrium, to ensure they can work properly, produce energy, build muscle, and keep our body going.
When these aren't properly balanced we can get headaches, brain fog, low levels of energy, muscle cramps, slower recoveries from workouts, and imbalances in hormones.
But when everything is in place, we have the most powerful you that you can be.
So let’s see how this works.
While Heart Rate measures the amount of beats per minute of your heart, and Resting Heart Rate measures the amount of beats per minute when your body is at rest (not active), Heart Rate Variability measures the natural variation in time between beats.
When we measure heart rate (how many beats per minute), we’re getting a large picture of how the heart is doing. For example, if we’re running or exercising, our heart speeds up. Then, when we’re resting, it slows down.
Before we cover what actually causes Heart disease, I want to cover something that doesn’t, or at least not in the way most people think: Cholesterol.
You’ve probably heard of the Cholesterol Hypothesis.
This hypothesis states that higher levels of cholesterol, particularly LDL Cholesterol, are associated with higher rates of Heart Disease.
To prevent heart disease then, we take drugs known as statins that lower our liver’s ability to produce cholesterol.
This hypothesis has been so deeply ingrained in our understanding of how the body works, that the idea of challenging it is almost laughable. (Even though it’s still just a hypothesis after all this time.)
