Often thought as a "physique destroyer", dietary
fat is actually one of the most critical players when it comes to optimizing
natural testosterone production. Long gone are the days in which we associate
fat with heart disease and elevated cholesterol levels; it's now recognized as
a sure way to increase testosterone levels. In fact, a study published in the
"Journal of Applied Physiology" found that diets with higher amounts
of monounsaturated and saturated fats have been shown to increase testosterone
levels.1
In another study, men who switched from a high-fat diet (13
percent saturated fat) to a low-fat diet (5 percent saturated fat) experienced
significantly lower testosterone production rates, and lower circulating
androgen levels.2
"Keep in mind that when it comes to dietary fat, it's
not just the amount of fat you eat, but also the type of fat," says Don
Gauvreau, MSc, co-founder PharmaFreak .
Olive oil, almonds, avocados, peanut butter
EXAMPLES OF QUALITY SATURATED FATS:
Red meat, coconut oil, egg yolks, dark chocolate, cheese
2 DON'T AVOID CHOLESTEROL
Testosterone is derived from cholesterol, so it should come
as no surprise that if your diet is lacking in cholesterol, you're also more
than likely shortchanging yourself when it comes to the muscle-building
hormone. Previous research has demonstrated a strong relationship between HDL
cholesterol levels and free testosterone levels.3 Keep in mind that the
majority of testosterone in your body is bound to proteins, but only the
unattached, or free, testosterone is considered bioavailable and readily
available for tissue uptake.
Furthermore, incorporating whole eggs into a moderately
carbohydrate-restricted diet was shown to improve the lipoprotein profile
(increased HDL cholesterol) and reduce insulin resistance in individuals with
metabolic syndrome, a constellation of health issues that includes hypertension,
abnormally high blood glucose, and other risk factors for heart disease.4
Top cholesterol-containing foods are typically the ones that
are high in saturated fats. Some of your best choices are red meat, egg yolks,
and seafood such as shrimp, squid, and lobster. Whole eggs are a staple in my
diet—I eat three every morning!
3 CONSUME TEST-BOOSTING INGREDIENTS
TESTOFEN® (FENUGREEK EXTRACT)
Testofen®, a standardized extract of fenugreek, is thought

support free testosterone levels, muscle mass, and sexual drive in men. While
the research is still somewhat new in this area, a study out of Australia found
that six weeks of supplementing with a formula containing Testofen® as a major
ingredient showed statistically significant increases in performance, sexual
function, and satisfaction in healthy adult males.5
ZINC
Zinc is an essential mineral that plays a critical role in
testosterone production. Mild zinc deficiency, commonplace among men and women
in the United States, has been associated with suppressed testosterone
concentrations. A notable study out of Wayne State University in Indiana found
that older men who had a mild zinc deficiency significantly increased their
testosterone from 8.3 to 16.0 nmol/L—a 93 percent increase!—following six
months of zinc supplementation. Researchers of the study concluded that zinc
may play an important role in modulating serum testosterone levels in normal
healthy men.6
D-aspartic acid (DAA) is an amino acid present in
neuroendocrine tissues and is believed to impact hormone levels by increasing
the activity of testosterone production. In one human study, 23 men were given
a daily dose of 3,120 mg of DAA for 12 days, whereas another group was given a
placebo. After just 12 days, the subjects supplementing with DAA experienced an
increase in testosterone by an average of 42 percent and luteinizing hormone
(LH) by an average of 33 percent. The results of this study show that DAA may
have a key role in the regulation of the release and synthesis of LH and
testosterone in humans.7
VITAMIN D
Vitamin D is arguably the most important vitamin when it
comes to testosterone. A study published in the "Journal of Clinical
Endocrinology" examined the relationship between vitamin D supplementation
and testosterone levels in men. The authors found that participants with higher
levels of vitamin D had significantly higher levels of free testosterone
compared to those with insufficient levels of vitamin D.8 Based on these study
results, it appears vitamin D has a strong relationship with testosterone levels.
DIINDOLYLMETHANE (DIM)
Diindolylmethane (DIM) is a component of indole-3-carbinol
and formed during the digestion of vegetables such as broccoli and cauliflower.
Research suggests that DIM can help support a healthy balance of the sex
hormones estrogen and testosterone in the body. It does this by converting
potent forms of estrogen into less potent forms, reducing the overall effects
of estrogen in the body.9 The end result is a more balanced hormonal
environment for healthy testosterone production!
4 FAVOR MULTIJOINT FREE-WEIGHT MOVEMENTS
Just as your diet has a major influence on testosterone
levels, so does how you train. Research has proven time and time again that
high-intensity weight training (choosing weights so that you reach muscle
failure by 10 reps) can stimulate increases in testosterone secretion. However,
you must also choose the right exercises and the right tools of the trade if
you want to take full advantage of this T-boost. Essentially, the more muscle
mass you stimulate, the more testosterone you'll secrete. A recent study
conducted on trained subjects showed that squats stimulated a greater
testosterone response when compared to leg presses.10 Stick with multijoint
exercises like squats, bench presses, and deadlifts—as they are prime examples
of the kinds of compound lifts that'll help significantly jack up your
testosterone levels! Since machines better isolate a muscle you're working
(less stabilizer activity), they're not as good a choice compared to free
weights.
