When it comes to men's health, the conversation often revolves around testosterone levels and ways to boost this vital male hormone. However, few realize that the foods men eat can significantly impact their body's ability to produce testosterone optimally. This article explores the connection between diet, gut health, and testosterone with renowned expert Dr. Robert Silverman.
Dr. Silverman is a chiropractic doctor, clinical nutritionist, speaker, and author of the Amazon bestseller "Inside-Out Health." As the founder and CEO of Westchester Integrative Health Center, he has helped countless patients understand how their gut health influences various aspects of their well-being, including hormone production.

The Gut-Testosterone Connection
According to Dr. Silverman, the link between gut health and testosterone levels is rooted in a phenomenon known as the "GELDING theory" – Gut Endotoxin Leading to a Decline IN Gonadal function. He explains:
"Essentially, gut health and damage to gut health leads you down a path of decreased testosterone because if you've got a compromised gut and you release something called LPS, or lipopolysaccharide, which holds gram-negative bacteria on the inside of the intestinal wall. When that gets through it hangs on the outside of the wall... and it gets through into the bloodstream, it's called an endotoxin. This endotoxin attaches to the testes and causes a decreased production in testosterone."
In simpler terms, when the gut lining becomes compromised (a condition known as "leaky gut"), harmful substances like bacteria and toxins can escape the intestines and enter the bloodstream. These endotoxins can then travel to the testes, disrupting the body's natural testosterone production.
The Role of Inflammation
Inflammation is a key player in this gut-testosterone dynamic. Dr. Silverman emphasizes that inflammation, particularly hidden or chronic inflammation, is a primary driver of many diseases and conditions. And one of the main sources of this harmful inflammation? Food sensitivities.
"I believe that food sensitivity is that source or one of those main sources of hidden inflammation," says Dr. Silverman. "Now, why is food sensitivity so interesting versus food allergy? Well, a food allergy is real easy in that you'll know it. I mean, you'll go around itch you'll swell and you'll say, 'I'm not going to eat that shrimp,' 'I'm not going to eat that peanut' you know it, but if you were sensitive to that nut, you wouldn't know it."
Unlike food allergies, which trigger immediate and obvious reactions, food sensitivities can manifest up to 72 hours after ingestion, making them challenging to identify without proper testing. According to Dr. Silverman, the prevalence of food sensitivities has increased by 50% in adults and 70% in children over the past five years.
Common culprits include dairy, soy, eggs, wheat, peanuts, tree nuts, fish, and shellfish, as well as food additives and emulsifiers. When these problematic foods are consumed regularly, they can contribute to a chronic state of inflammation in the gut, setting the stage for a leaky gut and the subsequent decline in testosterone production.
Testing for Food Sensitivities
To help his patients identify potential food sensitivities, Dr. Silverman relies on KBMO Diagnostics' 176-Fit test, which screens sensitivities to 176 different foods, additives, and emulsifiers.
"What's unique about this 176, in addition it adds in additives and emulsifiers, but it's a unique test. It's the only test that tests for what we call IgG and everybody knows IgG is an antibody. There's actually four IgG's, one through four. Most testing companies test IgG one through two. KBMO tests one through four."
The Gut-Brain-Testosterone Axis
The connection between gut health and testosterone production extends beyond the gut-testes relationship. Dr. Silverman emphasizes the importance of the gut-brain axis, which refers to the bidirectional communication between the gut and the brain.
"Whatever you do to your gut you do to your brain, whatever you do to your brain, you do to your gut," he says. "Your brain reads and registers to specific nerve impulses through this nerve called the vagus nerve, cranial nerve number 10, the great wonderer. The vagus nerve communicates through a neuronal impulse from the gut to the brain, and the brain and the gut."
This intricate communication pathway means that gut inflammation and dysfunction can impact brain function and vice versa. Given the brain's role in regulating hormone production, including testosterone, maintaining a healthy gut-brain axis is crucial for optimal testosterone levels.
Beyond Food: Other Factors Affecting Gut Health
While diet plays a pivotal role in gut health, Dr. Silverman emphasizes that various other factors can also contribute to gut dysfunction and impact testosterone production. These include:
- Antibiotics: Overuse of antibiotics can severely disrupt the delicate balance of gut bacteria, leading to dysbiosis and inflammation.
- Proton Pump Inhibitors (PPIs): Acid-blocking drugs like PPIs, often taken for heartburn, can impair gut function when used long-term.
- Environmental Toxins: Exposure to heavy metals, pesticides, and other toxins can damage the gut lining and contribute to a leaky gut.
- Stress and Sleep Deprivation: Chronic stress and insufficient sleep can impair gut function and exacerbate inflammation.
- Alcohol and Nicotine: Both alcohol and nicotine can damage the gut lining and disrupt the gut microbiome.
Lifestyle Recommendations
To maintain a healthy gut and support optimal testosterone levels, Dr. Silverman offers several lifestyle recommendations:
1. Avoid GPS: Gluten, Processed Foods, and Added Sugars
"Understand that it's diet, exercise, and mindset. I'll give you a couple of acronyms to remember on foods that you definitely want to avoid because you cannot run a bad diet and you cannot supplement a bad diet. That said, GPS. GPS, no gluten, no processed food, no added sugar."
2. Ditch DNA: Dairy, Nicotine, and Artificial Sweeteners
"Take care of your DNA, no dairy, no nicotine, no artificial sweeteners."
3. Eliminate Vegetable Oils
"Avoid vegetable oils. Vegetable oils are not vegetables. They're seed oils and they're used most commonly in restaurants. Everybody after today, please, whatever you do, become allergic to vegetable oils and make them cook with something else."
4. Get Tested
"Go test and see if you have a food sensitivity or a leaky gut because the gut is the epicenter of your health."

The Importance of a Holistic Approach
Throughout the conversation, Dr. Silverman emphasizes the importance of a holistic approach to health that recognizes the interconnectedness of various body systems and the impact of lifestyle factors on overall well-being.
"You want to test and not guess. I believe serum tests and many of these functional medicine tests are great baselines to be added into any doctor's armamentarium," he says. "For me, again, the gut is the epicenter of your health. It's a great choice to start looking at for vast different things. It's not the end-all but it's probably at least the starting point."
The connection between men's food choices, gut health, and testosterone production is undeniable. By being mindful of their dietary habits, identifying potential food sensitivities, and addressing other factors contributing to gut dysfunction, men can support their body's natural ability to produce testosterone and maintain overall health. As Dr. Silverman wisely notes, "Take care of your body it's the place you have to live."
