Longevity Optimization with Kayla Barnes-Lentz

Prof. Belinda Beck, PhD, a bone physiology researcher and LIFTMORE trial leader who changed how we think about osteoporosis. She discusses how bone peaks at 18, why early activity matters, and the trial showing twice-weekly heavy resistance and impact training can increase bone density. Short safety and testing notes on DEXA, impact progression, and age-specific exercise timing.

Dr. Dawn Mussallem, integrative oncologist, lifestyle medicine specialist, stage 4 cancer survivor and heart transplant recipient, shares her story and clinical lens. She discusses rising cancer rates, prevention basics, the power of exercise, metabolic health, sleep, fiber, gut microbiome, advanced screening tools like MRI and liquid biopsies, and practical nutrition tips.

Dr. Brian Kennedy, PhD, a leading biochemistry and aging researcher directing the Center for Healthy Longevity in Singapore. He breaks down how scientists study aging and why molecules like rapamycin and metabolic drugs draw attention. Conversations cover measuring biological age, diet and fasting, exercise and sleep, reproductive aging, and practical low-cost steps people can try.

Dr. Sara Szal, MD, a physician specializing in functional and women’s health, microbiome medicine, hormones, bone health and longevity. She explores the gut-brain link and how antibiotics can disrupt mood and immunity. Hear a practical Weed, Seed, Feed approach to rebuild the microbiome. They also debate GLP-1s, bone and muscle risks for women, and the promise and pitfalls of peptides.

Bérénice Benayoun, associate professor studying female-specific aging and the gut-ovary axis. She explains why ovaries age faster than other tissues. Short takes cover DNA damage, mitochondrial decline, fibrosis, hormonal signaling, and a surprising gut microbiome finding that improved ovarian reserve in mice. The conversation highlights menopause as a broad healthspan issue and emerging translational directions.

Dr. Deb Rivera, neuroengineer and CEO who studies mitochondrial resilience, explains the glutathione ratio as a hidden biomarker of stress adaptation. Short, vivid stories and practical routines illustrate redox balance, mitochondria–gut ties, sleep and recovery, and environmental impacts. Conversation also covers testing glutathione, therapeutic trade-offs, and everyday ways to support resilience.

Dr. Eboni Cornish, a board-certified physician and functional medicine director focused on neuroinflammation and chronic infections. She discusses hidden drivers of brain problems like mold, Lyme, toxins, and oral/gut imbalances. Imaging and biomarkers that reveal early brain stress come up. Practical foundations for brain longevity such as sleep, exercise, omega-3s, vitamin D, hormones, and detox are highlighted.

Jessie Inchauspé, biochemistry-trained author known as the Glucose Goddess, explains why blood sugar patterns matter for mood, energy, cravings, skin aging, and pregnancy. She shares surprising CGM discoveries, common glucose mistakes, simple stabilizing hacks like food order and walking, and how maternal spikes can shape a child’s long-term metabolic risk.

Dr. Deanna Minich, PhD, a functional medicine practitioner and nutrition scientist. She explains circadian timing for meals, macro ranges tailored to pre-, peri-, and postmenopause, and why flexible ranges beat rigid targets. They cover carb roles for ovarian health, protein strategies for aging, omega-3 testing, fiber goals, and practical cooking and oil choices to protect metabolic and bone health.

Dr. Susanna Søberg, PhD, scientist and educator focused on metabolism, cold and heat exposure, and longevity. She explains cold as a short hormetic stressor, why brown fat matters for metabolic health, and how timing cold around the menstrual cycle can change effects. Short, strategic cold exposures and combining cold with heat or exercise get emphasis.
