Exercise, meal timing, and sleep are three powerful tools for optimizing metabolic health, a key factor in healthy aging. Even slightly elevated blood glucose levels, but within the "normal" range, can contribute to brain atrophy in areas linked to aging and neurodegeneration. Long-term glucose elevations (high HbA1c) also promote harmful compounds that stiffen blood vessels, reduce heart flexibility, and raise cardiovascular risk. In this episode, recorded at the American Academy of Anti-Aging Medicine conference in Palm Beach, Florida, I provide practical, science-backed protocols on how to implement HIIT, circadian-timed eating, and optimized sleep strategies to dramatically improve metabolic health and protect against these harmful effects.
