The Most Overlooked Number in Your Blood Test (and Why It Matters More Than You Think)

from The Habit Healers · host Laurie Marbas, MD, MBA

In this episode, I walk you through one of the most overlooked numbers on your bloodwork — something almost nobody talks about: ApoB.Think of it like this…It’s not just how much cholesterol is floating around in your bloodstream — it’s how many little particles are actually hitting your artery walls.Imagine someone throwing darts at you. Even if the darts are small, the more darts, the greater the damage. That’s exactly what ApoB is measuring — it’s basically a particle counter for the dangerous cholesterol-carrying lipoproteins in your blood.I break down the three main particles that matter most for heart risk:LDL (low-density lipoprotein)VLDL (very low-density lipoprotein)Lp(a) (lipoprotein(a))Most people only look at total cholesterol or LDL… but ApoB can actually give you a much clearer picture of your real heart disease risk.Give this episode a listen — you’ll come away knowing why ApoB may be even more important than your standard cholesterol levels, and what it means for your long-term heart health.Here is the link to the Substack article: https://drlauriemarbas.substack.com/p/the-most-dangerous-number-in-yourA Big Thank You To Our Sponsors: If you want the best supplement to help you on your plant-based journey, you have to try Complement: https://lovecomplement.com/?aff=62If you are over the age of 50 and want to improve your body composition, build lean muscle (combat sarcopenia), build stronger bones (to combat osteoporosis), and you want to feel your best, I highly recommend exploring the life-changing coaching offered at https://www.fitvegancoaching.com/ Their personalized, whole-food, plant-based approach helped me lose 7% body fat, gain lean muscle, and even improve my running time—all while feeling energized and healthy.
