6 Surprising Hormone Truths That Defy Common Wisdom

We all strive for peak vitality that feeling of boundless energy, sharp focus, and steady drive. Yet, many hit an invisible wall, grappling with sluggishness or a nagging sense they’re not operating at full capacity. The search for answers often points to hormones, but the conversation is usually oversimplified into generic rules that fail to capture the intricate, personal reality of our biochemistry.

True hormonal optimization requires moving beyond one-size-fits-all advice. Some of the most powerful levers are surprising, even counter-intuitive, and well-intentioned habits can backfire without the right context. Drawing on insights from Dr. Kyle Gillett on the Huberman Lab Essentials podcast, we explore six takeaways that challenge conventional wisdom and provide a smarter roadmap to unlocking your vitality.

1. Can Eating Less Lower Testosterone in Healthy Men?

Direct Answer: Yes. While caloric restriction improves testosterone in individuals with obesity or metabolic syndrome, it can have the opposite effect, lowering testosterone in young, healthy, lean men.

Explanation & Evidence:
Health strategies are not universal. A systematic review highlights this critical nuance: the hormonal impact of eating less depends entirely on your starting metabolic state. For an already healthy individual, an aggressive calorie cut may undermine the very vitality they seek.

Analysis & Application:
This is a crucial lesson in context. If you’re lean, healthy, and pursuing peak performance, prioritize nutrient density and energy balance over severe restriction. Chronic undereating can signal scarcity to your body, downregulating hormones tied to reproduction and vitality. Focus on fueling performance.

2. Could Your “Healthy” Diet Be Blunting Your Motivation?

Direct Answer: Possibly. Certain celebrated plant compounds, like curcumin in turmeric and piperine in black pepper, can inhibit the enzyme that produces dihydrotestosterone (DHT), a potent driver of motivation, libido, and assertiveness.

Explanation & Evidence:
DHT is a key androgen that contributes to the feeling that “effort feels good.” Dr. Gillett notes that highly bioavailable extracts of common anti-inflammatory polyphenols may inadvertently blunt this pathway.

For individuals with already low DHT or less sensitive androgen receptors, “supplementing with these might actually be detrimental to that feeling of motivation and well-being.”

Analysis & Application:
Don’t indiscriminately mega-dose isolated anti-inflammatory supplements. If you struggle with low drive or motivation, assess your intake of concentrated polyphenol extracts. Getting these compounds from whole foods within a balanced diet is less likely to cause issues than high-potency supplements.

3. Do Women Have More Testosterone Than Estrogen?

Direct Answer: Yes. Almost all women have significantly more total testosterone in their bodies than estradiol (the primary estrogen), challenging the reductive label of testosterone as a “male” hormone.

Explanation & Evidence:
This fact is often missed because the hormones are measured on different scales (nanograms vs. picograms), and most testosterone is bound to SHBG protein, making it inactive. This oversight can obscure a complete picture of female hormonal health.

Analysis & Application:
Recognizing testosterone as a major player in female health is essential. Women experiencing low energy, diminished muscle tone, or low libido should consider a full hormone panel that includes total and free testosterone, not just estrogen and progesterone. A complete view is critical for long-term health and pathology prevention.

4. Why Might Starting Testosterone Therapy Ruin Your Sleep?

Direct Answer: Initiating Testosterone Replacement Therapy (TRT) can increase the risk of sleep apnea, especially in the first 1-2 months, by potentially triggering a hyper-sympathetic state that destabilizes the airway.

Explanation & Evidence:
While low testosterone can cause poor sleep, correcting it isn’t always straightforward. The therapy itself can introduce new complications, particularly at higher doses or in men who started with normal levels.

Analysis & Application:
This highlights that more hormone is not always better. If starting TRT, prioritize sleep monitoring. Be aware of new snoring, gasping at night, or daytime fatigue. Using the lowest effective dose and working with a knowledgeable clinician who monitors for these side effects is paramount for safe treatment.

5. Is Your Relationship Affecting Your Hormones?

Direct Answer: Absolutely. Romantic relationships involve a constant “pheromonal and hormonal cross talk.” Purposefully spending time apart can help regulate dopamine and maintain attraction, while major shared life events like pregnancy cause synchronized hormonal shifts in both partners.

Explanation & Evidence:
Hormones mediate connection. Dr. Gillett observes that perpetual togetherness can dampen excitement, while planned separation can renew it.

“A lot of guys know that when they go on a trip… they come back and see their partner and it’s almost like a new relationship… Purposely building that into every relationship can help significantly.”

Analysis & Application: Strategically build independent time and novel experiences into your long-term relationship. This isn’t about distance but about refreshing your individual and shared neurochemistry. Also, understand that events like having a child will naturally alter hormones like prolactin and dopamine in both partners—planning for this can ease the transition.

6. Is “Spirit” a Real Pillar of Hormone Health?

Direct Answer: Yes. Dr. Gillett positions “Spirit”—your sense of purpose, belief, and connection—as the sixth and foundational pillar, arguing that the mind, body, and soul are an interconnected system.

Explanation & Evidence:
Even with perfect diet, exercise, and sleep, a lack of spiritual well-being can profoundly impact physical health. This moves purpose from a philosophical concept to a clinical consideration.

“If you have all the other five [pillars] dialed in completely but you don’t have your spiritual health… then that’s going to profoundly impact your body and your mind as well.”

Analysis & Application:
Your optimization plan is incomplete without inner work. Actively cultivate your sense of purpose and connection. This could be through community, meditation, nature, faith, or creative pursuits. Auditing your spiritual health is as important as auditing your nutrition for holistic well-being.

Your Hormone Health Questions, Answered

Q: I’m a healthy man trying to get lean. How can I cut calories without crashing my testosterone?
A: Avoid aggressive, prolonged deficits. Opt for a modest deficit (300-500 calories below maintenance), prioritize high protein intake (to support muscle and satiety), and incorporate diet breaks or refeed days every 6-8 weeks to temporarily restore energy intake and help normalize hormone levels.

Q: Should women worried about high testosterone avoid strength training?
A: No. This is a common misconception. Regular strength training is crucial for female bone health, metabolic rate, and functional strength. It does not cause abnormally high testosterone levels. The benefits far outweigh any unfounded concerns. For more on this, see our guide on [strength training for women’s health].

Q: Are there signs that my TRT might be causing sleep apnea?
A: Key signs include new, loud snoring; witnessed episodes where you stop breathing at night; choking or gasping sensations; and unrefreshing sleep despite adequate time in bed. If you notice these, consult your prescribing physician immediately for a sleep evaluation.

Q: How do I practically “work on” the spiritual pillar?
A: Start with reflection. Ask: What gives me a sense of meaning? When do I feel most connected? Dedicate 10-15 minutes daily to an activity that fosters this, whether it’s journaling, walking without technology, volunteering, or a mindfulness practice. Consistency in small doses is key.

Optimizing your hormones is a nuanced journey that defies simple rules. As these insights show, true vitality comes from understanding the complex interplay between metabolism, lifestyle, relationships, and even your sense of purpose. It’s about intelligent application, not blind adherence to trends.

Which of these six surprising pillars presents the greatest opportunity for you to refine your approach? Lasting vitality is built by integrating these layers, not by fixating on just one.
