The Health Edge: translating the science of self-careAuthor: Mark Pettus MD and John Bagnulo PhD, MPH
Its not what we dont know that gets us into trouble. Its what we know that aint so. Will RogersWe believe the explosion of life science research from many disciplines had catapulted ahead of our capacity to process, integrate, understand, and apply. We are interested in translating all that is out there as news to use. A fundamentally different understanding of human biology has emerged. The implications from the perspective of self-care are profound. We are rapidly moving away from the debate of nature versus nurture toward an understanding that life emerges from a dynamic landscape of nature via nurture. We are passionate about the science. We are passionate about the implications. We believe in the capacity and possibility made possible by being alive here and now! We are beautifully designed to be on the African Savannah, living fully integrated with our planet, and in the context of social relationship. Our modern environment is not well designed to promote human health and the capacity to thrive. Many are struggling to maintain balance and traction in lives that often feel overwhelming and frightening.The challenge is to better leverage our superb ancestral adaptation for a different and radically challenging modern environment. Everything that touches us today has the potential be be very familiar or totally foreign. The less aware one is of the day to day distance between what we are biologically , as a species, familiar with and what we actually encounter, the fewer the possibilities for more effective alignment. Leaving ones health trajectory to chance in our modern environment is a very risky proposition. We are interested in holding the science to the light with an open and humbled mindset. Like you, We are intrepid explorers interested in how we emerge in the midst of our relationship with the environmental inputs of our liveshow we eat, how we move, how we sleep, how we navigate the mind fields of conflict in our lives, how socially conn Language: en Genres: Alternative Health, Health & Fitness, Medicine Contact email: Get it Feed URL: Get it iTunes ID: Get it |

Chrononutrition And Biological Aging
Friday, 17 April, 2026
Send us Fan MailYour body keeps time, and your fork might be one of the strongest signals it listens to. We get into chrononutrition, the growing science of meal timing, and why aligning breakfast and dinner with circadian biology may change far more than your waistline. Using a new large-cohort analysis from NHANES, we talk through how first meal time, last meal time, and the length of your daily eating window correlate with biological aging models, including organ-specific aging patterns in the heart, liver, and kidneys.We also make the research practical. We share why late dinners and long grazing-style eating windows can push you toward insulin resistance, weight gain, and worse sleep, and why shutting down food earlier in the evening often becomes the “linchpin” habit that makes everything else easier. Then we zoom in on breakfast strategy, including why a high-protein, higher-fat morning meal can improve satiety, muscle protein synthesis, thermogenesis, and energy through the day, plus examples of simple high-protein breakfasts you can actually repeat.Finally, we explain biological age testing in plain language. We compare epigenetic clocks based on DNA methylation with functional blood-based models like KDM and PhenoAge, and why trending these markers can motivate real behavior change. If you care about healthy aging, metabolic health, time-restricted eating, better sleep, and a routine that works with your biology instead of against it, this conversation gives you a clear place to start.
