Story
at-a-glance
-
Beginning around age 30, a man’s testosterone levels
begin to decline, and continue to do so as he ages,
leading to symptoms such as decreased sex drive,
erectile dysfunction, depressed mood, and difficulties
with concentration and memory
-
Dietary and exercise changes, particularly limiting
sugar/fructose, eating healthy saturated fats and
engaging in high-intensity exercises and strength
training, can be very effective at boosting testosterone
levels naturally
-
Other strategies to boost testosterone include optimizing
your vitamin D levels and reducing stress
Testosterone,
a hormone produced primarily by the testicles, is
often associated with the epitome of "manhood" (although
women have testosterone, too).
Indeed,
it does play a large role in male sexuality and reproduction,
impacting such factors as sexual and reproductive
function, muscle mass, and hair growth, but also has
some less "flashy," albeit equally important, roles
like maintaining bone density, levels of red blood
cells and a sense of well-being.
Beginning
around age 30, a man's testosterone levels begin to
decline, and continue to do so as he ages.
A
wide range of chemical exposures included prescribed
drugs like statins, adversely impact testosterone
production in men. At the same time, estrogen levels
typically increase due to widespread exposures to
estrogen-mimicking compounds in food, water and environmental
pollutants.
What
are Your Options for Replacement?
If
you're a man who's experiencing symptoms such as decreased
sex drive, erectile dysfunction, depressed mood, and
difficulties with concentration and memory, and you
think low testosterone may be to blame, you can have
your levels tested. Since testosterone levels fluctuate
throughout the day, you'll probably need more than
a blood test to get a true picture of your levels.
If
your levels are indeed low, there are a number of
synthetic and bioidentical testosterone products on
the market, as well as DHEA, which is the most abundant
androgen precursor prohormone in the human body, meaning
that it is the largest raw material your body uses
to produce other vital hormones, including testosterone
in men and estrogen in women.
I
only recommend using bioidentical hormones, and only
then under the guidance of a holistic doctor who can
monitor your hormone levels to ensure you need supplementation.
But,
before you opt for this route, there are numerous
strategies you can try to boost your testosterone
levels naturally. These are appropriate for virtually
anyone, as they carry only beneficial "side effects."
9
Ways to Naturally Increase Testosterone Levels
1. Lose
Weight
If
you're overweight, shedding the excess pounds may
increase your testosterone levels, according to research
presented at the Endocrine Society's 2012 meeting.
Overweight men are more likely to have low testosterone
levels to begin with, so this is an important trick
to increase your body's testosterone production when
you need it most.
If
you are serious about losing weight, you have got
to strictly limit the amount of processed sugar in
your diet, as evidence is mounting that excess sugar,
and fructose in particular, is the primary driving
factor in the obesity epidemic. So cutting soda from
your diet is essential, as is limiting fructose found
in processed foods, fruit juice, excessive fruit and
so-called "healthy" sweeteners like agave.
Ideally
you should keep your total fructose consumption below
25 grams per day and this includes fruits. This is
especially true if you have insulin resistance and
are overweight, have high blood pressure, diabetes
or high cholesterol.
In
addition to eliminating or severely limiting fructose,
it will be vital to eliminate all grains and milk
(even raw) in your diet. Milk has a sugar called lactose,
which has been shown to increase insulin resistance
so it will be wise to avoid it if you are seeking
to lose weight.
Refined
carbohydrates like breakfast cereals, bagels, waffles,
pretzels, and most other processed foods also quickly
break down to sugar, increase your insulin levels,
and cause insulin resistance, which is the number
one underlying factor of nearly every chronic disease
and condition known to man, including weight gain.
As
you cut these dietary troublemakers from your meals,
you need to replace them with healthy substitutes
like vegetables and healthy fats (including natural
saturated fats!). Your body prefers the carbohydrates
in micronutrient-dense vegetables rather than grains
and sugars because it slows the conversion to simple
sugars like glucose, and decreases your insulin level.
When you cut grains and sugar from your meals, you
typically will need to radically increase the amount
of vegetables you eat, as well as make sure you are
also consuming protein and healthy fats regularly.
I've
detailed a step-by-step guide to this type of healthy
eating program in my comprehensive nutrition plan,
and I urge you to consult this guide if you are trying
to lose weight.
The
foods you choose to eat will be the driving force
behind successfully achieving your weight loss goals
high-intensity, short-burst-type exercises,
such as my Peak Fitness Program, two to three times
per week, combined with a comprehensive fitness plan,
is important too, and has an additional benefit as
well (see below)!
2. High-Intensity
Exercise like Peak Fitness (Especially Combined with
Intermittent Fasting)
Both
intermittent fasting and short intense exercise have
been shown to boost testosterone. Short intense exercise
has a proven positive effect on increasing testosterone
levels and preventing its decline. That's unlike aerobics
or prolonged moderate exercise, which have shown to
have negative or no effect on testosterone levels.
Intermittent
fasting boosts testosterone by increasing the expression
of satiety hormones including insulin, leptin, adiponectin,
glucagon-like peptide-1 (GLP-1), colecystokinin (CKK)
and melanocortins, all of which are known to potentiate
healthy testosterone actions, increase libido and
prevent age-related testosterone decline.
Having
a whey protein meal after exercise can further enhance
the satiety/testosterone-boosting impact (hunger hormones
cause the opposite effect on your testosterone and
libido). Here's a summary of what a typical high-intensity
Peak Fitness routine might look like:
- Warm
up for three minutes
- Exercise
as hard and fast as you can for 30 seconds. You
should feel like you couldn't possibly go on another
few seconds
- Recover
at a slow to moderate pace for 90 seconds
- Repeat
the high intensity exercise and recovery 7 more
times
As
you can see, the entire workout is only 20 minutes.
Twenty minutes! That really is a beautiful thing.
And within those 20 minutes, 75 percent of that time
is warming up, recovering or cooling down. You're
really only working out intensely for four minutes.
It's hard to believe if you have never done this that
you can actually get that much benefit from four minutes
of exercise. That's all it is.
Keep
in mind that you can use virtually any type of equipment
you want for this – an elliptical machine, a treadmill,
swimming, even sprinting outdoors (although you will
need to do this very carefully to avoid injury)
as long as you're pushing yourself as hard as you
can for 30 seconds. But do be sure to stretch properly
and start slowly to avoid injury. Start with two or
three repetitions and work your way up, don't expect
to do all eight repetitions the first time you try
this, especially if you are out of shape.
You
can find more information about this in an article
previously written on intermittent fasting.
3. Consume
Plenty of Zinc
The
mineral zinc is important for testosterone production,
and supplementing your diet for as little as six weeks
has been shown to cause a marked improvement in testosterone
among men with low levels.1
Likewise, research has shown that restricting dietary
sources of zinc leads to a significant decrease in
testosterone, while zinc supplementation increases
it2
and even protects men from exercised-induced
reductions in testosterone levels.3
It's
estimated that up to 45 percent of adults over the
age of 60 may have lower than recommended zinc intakes;
even when dietary supplements were added in, an estimated
20-25 percent of older adults still had inadequate
zinc intakes, according to a National Health and Nutrition
Examination Survey.4
Your
diet is the best source of zinc; along with protein-rich
foods like meats and fish, other good dietary sources
of zinc include raw milk, raw cheese, beans, and yogurt
or kefir made from raw milk. It can be difficult to
obtain enough dietary zinc if you’re a vegetarian,
and also for meat-eaters as well, largely because
of conventional farming methods that rely heavily
on chemical fertilizers and pesticides. These chemicals
deplete the soil of nutrients ... nutrients like zinc
that must be absorbed by plants in order to be passed
on to you.
In
many cases, you may further deplete the nutrients
in your food by the way you prepare it. For most food,
cooking it will drastically reduce its levels of nutrients
like zinc … particularly over-cooking, which many
people do.
If
you decide to use a zinc supplement, stick to a dosage
of less than 40 mg a day, as this is the recommended
adult upper limit. Taking too much zinc can interfere
with your body's ability to absorb other minerals,
especially copper, and may cause nausea as a side
effect.
4. Strength
Training
In
addition to Peak Fitness, strength training is also
known to boost testosterone levels, provided you are
doing so intensely enough. When strength training
to boost testosterone, you’ll want to increase the
weight and lower your number of reps, and then focus
on exercises that work a large number of muscles,
such as dead lifts or squats.
You
can “turbo-charge” your weight training by going slower.
By slowing down your movement, you’re actually turning
it into a high-intensity exercise. Super
Slow movement allows your muscle, at the microscopic
level, to access the maximum number of cross-bridges
between the protein filaments that produce movement
in the muscle.
5. Optimize
Your Vitamin D Levels
Vitamin
D, a steroid hormone, is essential for the healthy
development of the nucleus of the sperm cell, and
helps maintain semen quality and sperm count. Vitamin
D also increases levels of testosterone, which may
boost libido. In one study, overweight men who were
given vitamin D supplements had a significant increase
in testosterone levels after one year.5
Vitamin
D deficiency is currently at epidemic proportions
in the United States and many other regions around
the world, largely because people do not spend enough
time in the sun to facilitate this important process
of vitamin D production.
So
the first step to ensuring you are receiving all the
benefits of vitamin D is to find out what your levels
are using a 25(OH)D test, also called 25-hydroxyvitamin
D.
A
few years back, the recommended level was between
40 to 60 nanograms per milliliter (ng/ml), but more
recently the optimal vitamin D level has been raised
to 50-70 ng/ml.
To
get your levels into the healthy range, sun exposure
is the BEST way to optimize your vitamin D levels;
exposing a large amount of your skin until it turns
the lightest shade of pink, as near to solar noon
as possible, is typically necessary to achieve adequate
vitamin D production. If sun exposure is not an option,
a safe tanning bed (with electronic ballasts rather
than magnetic ballasts, to avoid unnecessary exposure
to EMF fields) can be used.
As
a last resort, a vitamin D3 supplement can be taken
orally, but research suggests the average adult needs
to take 8,000 IU's of vitamin D per day in order to
elevate their levels above 40 ng/ml, which is the
absolute minimum for disease prevention.
6. Reduce
Stress
When
you’re under a lot of stress, your body releases high
levels of the stress hormone cortisol. This hormone
actually blocks the effects of testosterone,6
presumably because, from a biological standpoint,
testosterone-associated behaviors (mating, competing,
aggression) may have lowered your chances of survival
in an emergency (hence, the “fight or flight” response
is dominant, courtesy of cortisol).
In
the modern world, chronic
stress, and subsequently elevated levels of cortisol,
could mean that testosterone’s effects are blocked
in the long term, which is what you want to avoid.
My
favorite overall tool to manage stress is EFT
(Emotional Freedom Technique), which is like acupuncture
without the needles. It's a handy, free tool for unloading
emotional baggage quickly and painlessly, and so easy
that even children can learn it. Other common stress-reduction
tools with a high success rate include prayer, meditation,
laughter and yoga, for example. Learning relaxation
skills, such as deep breathing and positive visualization,
which is the "language" of the subconscious.
When
you create a visual image of how you'd like to feel,
your subconscious will understand and begin to help
you by making the needed biochemical and neurological
changes.
7. Limit
or Eliminate Sugar from Your Diet
Testosterone
levels decrease after you eat sugar, which is likely
because the sugar leads to a high insulin level, another
factor leading to low testosterone.7
Based
on USDA estimates, the average American consumes 12
teaspoons of sugar a day, which equates to about TWO
TONS of sugar during a lifetime. Why we eat
this much sugar is not difficult to understand
it tastes good, and it gives us pleasure by triggering
an innate process in your brain via dopamine and opioid
signals.
What
it is doing to us on both a physical and emotional
level is another story entirely, and most people stand
to reap major improvements in their health by cutting
back on, or eliminating, sugar altogether from their
diets. Remember foods that contain added sugar and
fructose, as well as grains like bread and pasta,
should all be limited.
If
you're struggling with sugar addiction and having
trouble dealing with cravings, I highly recommend
trying an energy psychology technique called Turbo
Tapping, which has helped many "soda addicts"
kick their sweet habit, and it should work for any
type of sweet craving you may have.
8. Eat
Healthy Fats
By
healthy, this means not only mon- and polyunsaturated
fats, like that found in avocadoes and nuts, but also
saturated, as these are essential for building
testosterone. Research shows that a diet with less
than 40 percent of energy as fat (and that mainly
from animal sources, i.e. saturated) lead to a decrease
in testosterone levels.8
My
personal diet is about 60-70 percent healthy fat,
and other experts agree that the ideal diet includes
somewhere between 50-70 percent fat.
It's
important to understand that your body requires
saturated fats from animal and vegetable sources
(such as meat, dairy, certain oils, and tropical plants
like coconut) for optimal functioning, and if you
neglect this important food group in favor of sugar,
grains and other starchy carbs, your health and weight
are almost guaranteed to suffer. Examples of healthy
fats you can eat more of to give your testosterone
levels a boost include:
| Olives
and Olive oil |
Coconuts
and coconut oil |
Butter
made from raw grass-fed organic milk |
| Raw
nuts, such as, almonds or pecans |
Organic
pastured egg yolks |
Avocados |
| Grass-fed
meats |
Palm
oil |
Unheated
organic nut oils |
9. Boost
Your Intake of Branch Chain Amino Acids (BCAA) from
Foods Like Whey Protein
Research
suggests that BCAAs result in higher testosterone
levels, particularly when taken along with resistance
training.9
While BCAAs are available in supplement form, you'll
find the highest concentrations of BCAAs like leucine
in dairy products – especially quality cheeses and
whey protein.
Even
when getting leucine from your natural food supply,
it's often wasted or used as a building block instead
of an anabolic agent. So to create the correct anabolic
environment, you need to boost leucine consumption
way beyond mere maintenance levels.
That
said, keep in mind that using leucine as a free form
amino acid can be highly counterproductive as when
free form amino acids are artificially administrated,
they rapidly enter your circulation while disrupting
insulin function, and impairing your body's glycemic
control. Food-based leucine is really the ideal form
that can benefit your muscles without side effects.
