Biological aging doesn't have to match your birth certificate—and that truth could change everything.

In this episode of The Lisa Fischer Said Podcast, Lisa sits down with Dr. Mark Sherwood to unpack how biological age, circadian rhythm, and metabolic health determine how long—and how well—we live. Dr. Sherwood explains why Americans are "living longer but dying slower," how food timing impacts hormones and cortisol, and why eating after sunset may be accelerating aging.

They dive into intermittent fasting, insulin resistance, food noise, GLP-1 medications like Ozempic, and why weight loss alone is the wrong goal. Dr. Sherwood also breaks down biological age testing, peptides, inflammation, muscle loss, and how to extend health-span—not just lifespan. This is a practical, science-backed conversation that challenges conventional wisdom and reframes what "normal aging" really looks like.
