    Starving Cancer: A Metabolic Therapy Approach (Episode 25)

    Metabolic therapy as a promising complementary cancer treatment. This approach focuses on depriving cancer cells of essential energy sources like glucose, glutamine, and fatty acids, using a combination of drugs, supplements, dietary changes, and integrative therapies. The "press-pulse" method involves consistent metabolic stress and intermittent, higher-intensity interventions. While showing promise, the article emphasizes the critical need for more robust clinical research to validate the effectiveness and safety of this approach when combined with conventional cancer treatments. Dr. Brian Lawenda calls for greater collaboration between researchers, physicians, and patients to advance research in this area of cancer care.

    Low-Dose Radiation Therapy for Osteoarthritis (Episode 24)

    This podcast details low-dose radiation therapy (LDRT) as a treatment for osteoarthritis. LDRT uses low doses of X-ray radiation to reduce inflammation and pain, offering a non-invasive, long-lasting alternative to NSAIDs, steroid injections, and surgery. Studies show significant pain relief in 60-72% of patients for 2-3 years or more, with minimal side effects and a low cancer risk. It's widely used in Europe and is gaining popularity in the U.S. due to its effectiveness and improved insurance coverage. The procedure is painless, requires minimal recovery time, and may delay or prevent the need for joint replacement surgery.

    Unlocking Better Health Through Gut Testing (Episode 23)

    The podcast reviews Dr. Brian Lawenda's article on the crucial role of gut health in overall well-being, arguing that imbalances like dysbiosis and leaky gut significantly impact energy, mood, and immunity, often manifesting as subtle symptoms. He highlights the importance of stool testing to identify these hidden issues early, even in seemingly healthy individuals. The article details how stress negatively affects gut health and proposes solutions such as probiotics, prebiotics, and stress management techniques to restore gut balance. A case study illustrates how a seemingly healthy patient, upon testing, revealed significant underlying gut problems. Ultimately, the article advocates for proactive gut health monitoring through stool testing to prevent the development of chronic conditions.

    Forever Chemicals: A Toxic Threat to Human Health (Episode 22)

    This podcast discussed Dr. Brian Lawenda's article on the pervasive presence and severe health risks associated with per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals." These man-made chemicals are highly persistent in the environment and the human body, accumulating over time and causing a wide range of health problems, including cancers, immune system dysfunction, and hormonal imbalances. Dr. Lawenda's article details how PFAS contaminate various products and water sources, stressing the urgent need for increased awareness, testing, and preventative measures. It also explores functional medicine approaches to address the health impacts of PFAS exposure. Finally, he offers practical steps individuals can take to minimize their exposure and support their body's detoxification processes.

    Semaglutide & Tirzepatide For Cancer Prevention (Episode 21)

    This podcast reviews Dr. Brian Lawenda's article examining semaglutide and tirzepatide, medications for insulin resistance and obesity and their role in cancer prevention. The podcast details the mechanisms of these drugs, focusing on their potent appetite-suppressing effects and resultant weight loss. It emphasizes the importance of comprehensive monitoring, including DEXA scans, to track body composition changes and prevent muscle loss. Lifestyle modifications, such as resistance training and high-protein diets, are presented as crucial components for optimal results. Finally, the podcast highlights the potential of these medications to reduce cancer risk by improving metabolic health and reducing inflammation.

    Blood Sugar, Insulin Resistance, and Cancer (Episode 20)

    Dr. Brian Lawenda's article argues that cancer is a metabolic disease fueled by high blood sugar and insulin resistance. He explains the Warburg Effect, where cancer cells preferentially use glucose for energy, and how insulin resistance, often undiagnosed, creates a perfect environment for cancer growth. The article emphasizes the importance of achieving optimal metabolic health, including maintaining low blood sugar levels, which can be monitored using Continuous Glucose Monitors (CGMs). Lawenda details lifestyle changes, such as diet, exercise, and stress management, to reverse insulin resistance and reduce cancer risk. Ultimately, the piece stresses proactive health choices to prevent cancer development.

    The Testosterone Crisis: Diagnosis and Treatment (Episode 19)

    Dr. Brian Lawenda (through podcasters) examines the significant decline in testosterone levels among men today compared to the 1980s. This decrease is attributed to poor diet, sedentary lifestyles, environmental toxins, stress, and insufficient sleep. The podcasters highlight the health consequences of low testosterone, including increased risks of obesity, diabetes, and cardiovascular disease. It emphasizes the importance of measuring free testosterone, not just total testosterone, for an accurate assessment of hormonal health. Finally, they discuss various medical interventions for low testosterone, including testosterone replacement therapy (TRT) and other options, along with lifestyle changes that can improve testosterone levels.
