      Episode 76 | A System Made of Accidents: The Hidden History Behind U.S. Healthcare – Ragav Sharma, DO
      Nov 26 2025
      Ragav Sharma, DO In this episode, we break down the surprising and often overlooked history of how the U.S. healthcare system came to be—not through strategy or design, but through a series of accidents, policy compromises, and economic incentives that spiraled into today’s crisis.We explore the roots of employer-based insurance, the rise of fee-for-service reimbursement, the unintended consequences of Medicare and the Affordable Care Act, and how hospitals, insurers, and physicians evolved into the fragmented landscape we live with today. From the explosive growth of consolidation to the misaligned incentives driving costs, access issues, and burnout, this episode explains why American healthcare works exactly as it does—and why fixing it requires understanding its origins.Whether you’re a clinician, policymaker, administrator, or simply a curious listener trying to understand why U.S. healthcare is so complex and costly, this deep dive uncovers the structural forces that still shape the system. You’ll learn how major policy decisions, market power, and historical quirks created the misaligned incentives that fuel skyrocketing prices, consolidation, administrative waste, and persistent inequities. Ragav's Social Media: Instagram Link Show Notes Key Topics CoveredHow employer-based insurance began by accident during WWII wage freezesThe rise of fee-for-service and how early insurance models locked in volume-based paymentMedicare and Medicaid’s structural influence on cost and system designHow technology and specialization shifted the system toward high-cost acute careWhy the ACA unintentionally accelerated consolidation among insurers and hospital systemsHow misaligned incentives across hospitals, payers, physicians, and patients drive today’s dysfunctionWhy U.S. healthcare prioritizes volume, pricing power, and market share over actual health outcomesWhat You’ll LearnWhy the system behaves exactly the way it doesHow economic incentives—not clinical priorities—shaped U.S. healthcareWhy costs continue to rise regardless of reform effortsWhy consolidation amplifies prices and reduces competitionThe historical context needed to understand meaningful solutionsIdeal ForCliniciansHealth policy professionalsStudents in medicine, public health, or health economicsAnyone trying to understand why U.S. healthcare feels so broken Join our Mailing List HERE: Mailchimp

      Episode 75 | The Deep Dive on Resistance Training; The Hidden Secrets Your Doctor Doesn’t Tell You – Ragav Sharma, DO
      Nov 19 2025
      Ragav Sharma, DO Ragav Sharma, DO is a Physical Medicine and Rehabilitation (PM&R) physician with training in interventional spine and musculoskeletal medicine. He formerly set powerlifting records and has also completed several races including ultramarathons. He is an avid proponent of resistance training and has coached others, obtaining a Certified Strength and Conditioning Specialist (CSCS) certification, for both general health and powerlifting goals. In this episode, Dr. Ragav Sharma breaks down the science and strategy behind resistance training — one of the most powerful tools for improving long-term health, performance, and longevity. We explore what the evidence says about strength training for muscle growth, fat loss, metabolic health, injury prevention, and healthy aging. If you’ve ever wondered how often to lift, what exercises actually matter, or whether resistance training is “safe,” this episode gives you the no-nonsense, research-driven answers. Dr. Sharma's Social Media Instagram Link Show Notes What Is Resistance Training?Resistance training involves contracting skeletal muscle against external resistance to challenge strength and stimulate muscle growth. That resistance can come from:Bodyweight exercisesFree weights (dumbbells, barbells, kettlebells)Resistance bandsMachinesHousehold objects (backpacks, water jugs, cinder blocks)Strength training is not just for athletes or bodybuilders. It is one of the most potent therapeutic tools we have for improving overall function, mobility, and longevity — and it should be accessible to everyone.The Evidence-Based Benefits of Resistance Training1. Improved Body CompositionResistance training:Increases fat-free mass (muscle)Reduces overall and visceral fatHelps preserve muscle during weight loss or GLP-1/GIP therapyPredicts lower mortality independent of BMIMuscle is metabolically protective. Higher muscle mass is associated with a lower risk of chronic disease and death, even in those with a high BMI.2. Stronger Bones and Lower Fracture RiskBone density peaks around age 25–30 and declines after 40, especially in women. Walking alone does little for bone mineral density.Mechanical loading — squats, deadlifts, step-ups, weighted carries — is essential for:Increasing bone densitySlowing osteopenia and osteoporosisReducing fracture riskMaintaining physical function later in lifeOne of the strongest demonstrations is the Lift More Trial, where women 60+ with diagnosed osteoporosis safely performed heavy squats and deadlifts twice per week. They improved bone density significantly, with only one mild strain in over 2,600 sessions.3. Cardiovascular BenefitsMany people assume aerobics is the only way to protect the heart. The data tells a different story:Any resistance training → 19% lower cardiovascular mortalityImproves LDL, HDL, triglycerides, blood pressureEnhances functional capacity in heart failure patientsThe best results come from combining aerobic exercise with strength training — but strength training alone has a meaningful impact.4. Improved Metabolic HealthStrength training increases insulin sensitivity through GLUT4 upregulation and:Lowers HbA1c in both type 1 and type 2 diabetesReduces visceral fat, a major driver of insulin resistanceImproves metabolic flexibilityFor people unable to tolerate high-impact cardio, resistance training becomes even more important.5. Mental Health BenefitsThe psychological benefits are just as powerful:Significantly reduces anxiety symptomsLowers depressive symptoms in adolescents and adultsBenefits occur regardless of strength gainsSimply engaging in resistance training reliably improves mood and mental well-being.6. Reduction in Chronic PainMovement is medicine — and resistance training consistently reduces pain:Decreases chronic low back painImproves pain and function in knee osteoarthritisHelps patients with fibromyalgia reduce fatigue and tender...

      Nov 12 2025
      Shounuck Patel, DO Join us for an inspiring conversation with Dr. Shounuck Patel, a leader at the forefront of interventional orthobiologics and musculoskeletal ultrasound. A proud alumnus of the Chicago College of Osteopathic Medicine (CCOM), Dr. Patel completed his residency at the prestigious Kessler Institute, followed by world-renowned fellowship training at the Orthopedic and Spine Specialists (OSS).Dr. Patel is a master instructor for the Interventional Orthobiologics Foundation, where he trains physicians globally in cutting-edge regenerative techniques. As the founder of the Patel Center for Functional Regeneration in Newport Beach, he has established a premier destination for patients seeking advanced, evidence-based musculoskeletal care.Internationally recognized for his expertise, Dr. Patel is a sought-after speaker on orthobiologics and ultrasound, sharing his knowledge at conferences and workshops around the world. He also serves as an associate clinical professor, mentoring the next generation of physicians at Western University and Touro College of Osteopathic Medicine.Passionate about education, Dr. Patel regularly shares practical insights and procedural pearls on Instagram and YouTube (@Regendrpatel), making high-level regenerative medicine accessible to clinicians and patients alike.Tune in to hear Dr. Patel’s journey, his approach to innovation in musculoskeletal medicine, and his commitment to teaching and advancing the field. Dr. Patel's Social Media: Instagram Linkedin Show Outline/Transcript What does preventive medicine mean to you?What is regenerative medicine? Can it be used preventively to help regular folks and/or athletes injury free?How did your career progress to what you do now? What does your practice look like on a day-to-day basis?Do you think there is any merit to stem cell therapies found outside of the USA that people often use for biohacking or “reversing aging?"What does the future of regenerative medicine look like?If someone asks you how to get healthy?
