The critical role of testosterone in male sexual function and muscle synthesis cannot be overstated. Furthermore, testosterone is intricately tied to brain health, specifically dopamine production, mental well-being, cognitive function, and cardiovascular health.
Alarmingly, testosterone levels in men have been experiencing a global decline. Since the 1980s, male testosterone has been decreasing at an average rate of roughly 1% per year.
Modern men’s testosterone levels are around 20% less than those of men at a similar age from the previous generation. As a result, we’re generally less robust, more overweight, less muscular, more lazy, less fertile, and less healthy than our predecessors.
However, as society wakes up to the significance of testosterone, numerous verified lifestyle interventions can aid in boosting its levels. Let’s dive into these strategies today.
Our bodies predominantly produce testosterone via the gonads, while the adrenal glands also secrete small amounts. Testosterone performs three main functions in our bodies:
- Testosterone circulates in the bloodstream in the form of free testosterone, assisting in the sculpting of defined body contours.
- Testosterone is bound by proteins such as albumin and sex hormone-binding globulin (SHGB).
- Testosterone can be converted into estrogen by the enzyme aromatase.
Given the above, the objective is to maximize the levels of circulating free testosterone. So, what should we monitor and improve upon to accomplish this goal?
1. Adequate Intake of Cholesterol, Fats, and Calories
Cholesterol is essential for hormone health. Insufficient consumption of cholesterol, healthy fats, and adequate calories can seriously limit your testosterone levels.
Research suggests that consuming approximately 0.8-1 gram of fat per kilogram of body weight per day is optimal for promoting balanced hormone levels. Moreover, the type and quality of fat ingested matters significantly. Omega-3 fatty acids stabilize hormone levels, accelerate cellular metabolism, and enhance sexual function. Conversely, omega-6 fatty acids and trans fats can negatively impact testosterone levels.
Long-term body fat reduction can improve hormone levels, but sustained extreme dieting—characterized by a significant calorie deficit and profoundly low-fat intake—can drastically depress testosterone levels. Hence, I share the following three recommendations for fat consumption:
· Prioritize high-quality fats. Aim to avoid foods high in oil and sugar and eliminate trans fats.
· Enhance your intake of omega-3 fats through high-quality foods (fish, meat) or nutritional supplements.
· Ensure that 20% of your daily caloric intake derives from fats to provide sufficient fuel for hormone production.
2. Enhance Sleep Quality
Most testosterone secretion happens overnight. Thus, if your sleep quality is poor, your testosterone levels may likely be at risk.
Sufficient sleep can attenuate the body’s inflammatory response and lower cortisol secretion. It also reduces sex hormone binding globulin (SHBG) levels, naturally elevating free testosterone concentrations.
So, what is considered ‘sufficient’ sleep? Researchers conducted an experiment wherein participants slept 10 hours daily, subsequently reduced to 5 hours in the final week. Results revealed that just a week of sleep deprivation led to a 10-15% drop in testosterone levels.
Age also affects testosterone levels—typically, human testosterone levels dip at 1-2% per year post-age 30. Furthermore, prolonged poor sleep quality can exacerbate this decline.
Sleep apnea is a sleep-related condition that often goes overlooked, It affects approximately 1 in 15 individuals, with 80% of those afflicted paying inadequate attention to it. Sleep apnea involves recurrent upper airway obstruction during sleep—usually characterized by soft tissue tremors causing loud snoring, followed by temporary cessation of breathing and yet more snoring. It’s a serious sleep disorder.
Recent research has linked sleep apnea to sudden cardiac death, stroke, and other severe health conditions. The main contributors to sleep apnea include poor breathing habits, extreme obesity, and excessive neck circumference.
How does this affect testosterone? Well, sound sleep is crucial for maintaining testosterone levels. If your sleep is interrupted consistently due to difficulty breathing, achieving the deep sleep phase vital for optimal testosterone synthesis becomes harder.
Consider employing aids like anti-snoring straps and nasal strips to improve nighttime breathing.
3. Soak Up Some Sun and Supplement with Vitamin D
Exposure to sunlight is excellent for regulating circadian rhythms, enhancing sleep quality, and boosting dopamine levels. Dopamine is not just a ‘feel-good’ neurotransmitter; its secretion can directly signal the testes to produce more testosterone.
Additionally, spending time under the sun can enhance the body’s vitamin D levels—an effect that can also be realized through supplementation with vitamin D. Research indicates that men in the bottom 20% for vitamin D levels tend to have lower testosterone concentrations than those in the top 20% for vitamin D levels.
4. Experiencing Success Elevates Testosterone
Research has shown that winners of competitive sports matches often exhibit higher testosterone levels during subsequent games than the losers, whose testosterone levels decrease significantly.
Healthy competition can stimulate testosterone production, encouraging harder work and increasing testosterone levels.
We frequently find that in physical fitness training, our biggest competition is ourselves. However, the principle remains the same. Continuing to experience a sense of victory fuels a positive hormonal cycle.
This highlights the importance of well-planned training regimes. Rather than rushing and hitting a performance plateau—resulting in disappointment—it’s more effective to progress slowly, achieving smaller goals consistently, instead of regularly facing frustration in not meeting unreachable targets.
5. Strategically Plan Each Training Session
Resistance training is known to boost testosterone levels. However, it’s not as simple as pushing yourself to the extremes.
Training with moderate weights (70-90% of 1RM) while avoiding frequent failure will substantially maximize testosterone gains. Frequently pushing to extreme weights or constantly hitting failure might lead to excessive stress and impede testosterone levels.
Research also suggests that when training extends beyond an hour, cortisol levels gradually rise while testosterone levels progressively decrease.
Moreover, extensive endurance training can elevate cortisol levels while diminishing testosterone.
To optimize testosterone levels, schedule strength training sessions before cardiovascular workouts (and when you are cardio optimally) or separate strength and aerobic exercises to mitigate the potential negative impact of aerobic training on testosterone levels.
6. Select Supplements Wisely and Incorporate Trace Elements
Magnesium deficiency is the second most common nutritional disorder after vitamin D deficiency. Magnesium plays a pivotal role in more than 300 biochemical reactions in the human body, including those related to sleep, recovery, and stress management—all of which are intricately linked with testosterone levels.
Zinc primarily supports testicular function, reproductive health, and immune function. Given the challenge of obtaining sufficient zinc and magnesium through our daily dietary intake, a supplement combining magnesium and zinc has almost become essential.
While the jury is still unsure whether creatine can directly boost testosterone levels, it enhances strength performance, increases muscle mass, and improves mitochondrial function. These benefits are particularly valuable for individuals suffering from hypogonadism.
7. Maintain a Regular Sex Life
Healthy testosterone levels and a vibrant sex life complement each other.
Research indicates that moderate sexual activity can noticeably elevate testosterone levels, while excessive sexual activity can lead to the contrary effect.
However, should you suspect low testosterone levels, it’s advisable to seek a comprehensive blood test at a healthcare facility and maintain annual reviews. This strategy helps determine whether you need long-term strategies for stimulating testosterone production.
