What if the future of weight loss and metabolic health isn’t just about new medications — but about access, personalization, and how the body adapts over time? In this episode of The Better Body Lab Podcast, we sit down with endocrinologist and obesity medicine specialist Dr. Rekha Kumar to explore the evolving science of GLP-1 therapies, hormone health, and sustainable health optimization.

Together, we examine how resilience, recovery, and performance are shaped within the “human ecology” of metabolism — where biology, mindset, environment, and daily habits intersect. We unpack the shift from injectable to oral GLP-1 medications, challenges around affordability and off-label prescribing, and how new delivery technologies may expand treatment access.

We also explore key drivers of metabolic dysfunction, including hormonal transitions, insulin resistance, and muscle loss, along with practical insights on microdosing strategies. Ultimately, we discuss how individualized, evidence-based care can support long-term vitality and performance resilience.

About Dr. Rekha Kumar:
Dr. Rekha Kumar is an internationally recognized leader in Obesity Medicine and serves as Senior Medical Advisor at Found, advancing personalized, technology-enabled weight management. She also practices endocrinology at New York-Presbyterian, helping bridge traditional care with digital health innovation.

What if optimizing longevity isn’t about chasing wellness trends — but about understanding how your cells create energy, repair damage, and adapt over time? In this episode of The Better Body Lab Podcast, we sit down with exercise scientist and longevity researcher Dr. Rachele Pojednic to explore the science behind NAD, supplementation myths, and sustainable health optimization.

Together, we examine how resilience, recovery, and performance are shaped within the “human ecology” of health — the interaction between biology, mindset, environment, and daily behavior. Dr. Rachele shares her journey from personal trainer to Stanford faculty and industry science leader, offering grounded insight into navigating longevity trends with evidence-based thinking.

This episode reinforces a key truth: sustainable energy, strength, and wellbeing are built through consistent habits — movement, nutrition, sleep, and stress regulation — not quick fixes or hype-driven protocols.

What if the future of health optimization, recovery, and longevity isn’t just about new therapies — but about understanding the science, safety, and regulation behind what we put into our bodies? In this episode of The Better Body Lab Podcast, we explore the evolving landscape of research peptides and how innovation, policy, and personal responsibility intersect within the human ecology of health.

Together, we unpack what peptides are, how they function as biological signaling molecules, and why growing public interest has outpaced scientific validation and regulatory clarity. We examine the current U.S. legal environment, including discussions around accessibility, compounding practices, and the realities of the FDA approval process. Our conversation highlights critical safety considerations such as supply chain transparency, third-party testing, and the difference between anecdotal outcomes and controlled human research.

We also explore how curiosity, resilience, and foundational habits — including sleep, nutrition, movement, and stress regulation — remain central to sustainable performance and wellbeing. This episode offers a grounded, evidence-informed perspective for anyone navigating wellness trends, longevity strategies, or emerging performance tools.
