Gary Brecka is a renowned human biologist, longevity expert, and one of the leading voices in data-driven health optimization. With more than two decades of experience analyzing human biomarkers, Gary has built a reputation for translating complex science into clear, actionable insights that help people live better, fuller lives.

Before launching his work in public health and media, Gary served as a leading mortality researcher in the life insurance industry, where he helped predict health outcomes using comprehensive medical and lifestyle data. That experience gave him a rare, behind-the-scenes understanding of how health risks are measured, priced, and predicted at the highest levels.

But Gary’s mission was never about predicting how long people live — it was about changing how well they live.

As the founder of The Ultimate Human, Gary has helped shape the modern conversation around longevity, healthspan, and personalized wellness. His work emphasizes prevention, measurable outcomes, and empowering individuals with the knowledge to take control of their health before problems arise.

Now, Gary Brecka brings that perspective to The Concierge Doc Podcast, joining Dr. Jason Littleton for a powerful conversation on health, fulfillment, and what it truly means to live a longer, more meaningful life. Together, they explore how data, proactive medicine, and personalized care can give people access to their lives — not just more years on the clock.

This is a conversation about longevity with purpose — and why health is the foundation of everything that matters.

Dr. Sahil Chopra is reimagining sleep as the single most powerful lever we have to extend vitality and unlock human potential. The Harvard-trained sleep physician explains how his company is pioneering continuous longitudinal sleep testing using medical-grade wearables and AI to create personalized interventions for patients.

• Traditional medicine fails patients with sleep issues by prescribing medications without investigating root causes
• Most physicians receive only four hours of education on sleep during medical school
• Multi-night sleep testing at home provides more accurate data than single-night lab studies
• Effective sleep assessment requires asking specific questions about falling asleep, staying asleep, feeling rested, and daytime tiredness
• Melatonin supplementation is most effective for circadian rhythm disruptions at doses of 0.5-3mg
• Key sleep hygiene principles include consistent sleep/wake times, bedroom darkness, morning light exposure, and reserving the bedroom only for sleep
• The best approach for weaning off sleep medications involves gradual tapering while monitoring sleep data
• For shift workers, strategies include melatonin, timed eating, and appropriate use of FDA-approved stimulants
• Dr. Chopra maintains his own sleep health through regular exercise, time-restricted eating, and consistent sleep/wake times
