Summary

High cholesterol has been treated as the main cause of heart disease for decades. But over the years, I've changed my mind. Today, I believe cholesterol is only part of the story, and that inflammation, insulin resistance, and metabolic health are often the real drivers of cardiovascular disease. In this encore episode, I'm revisiting one of my most talked-about Office Hours conversations to share how my thinking has evolved and why understanding the root cause of heart disease can completely change the way you approach prevention. In today's episode, I discuss: Why cholesterol alone is a poor predictor of heart disease—and the biomarkers I believe matter even more, including ApoB, lipoprotein(a), inflammation, and insulin resistance The surprising role sugar, refined carbohydrates, and metabolic dysfunction play in driving cardiovascular disease Why two people with the same cholesterol can have dramatically different heart disease risk—and how a personalized approach changes the conversation The nutrition, lifestyle, and testing strategies I use to help reduce inflammation, improve metabolic health, and lower cardiovascular risk at its source Heart disease isn't simply a cholesterol problem—it's often a metabolic and inflammatory problem. When you understand what's really driving your risk, you can stop chasing a single number and start addressing the underlying biology that supports lifelong cardiovascular health.

0:00.0	What if brain fog, anxiety, and mood swings aren't simply all in your head?
0:04.7	What if the health of your mind actually starts deeper in your body, in your gut,
0:09.7	and your hormones, metabolism, and your immune system?
0:12.3	Well, let me tell you, the connection is real, and it affects how you think and you feel
0:16.4	every single day.
0:17.3	And that's why I created Brain Shaping Academy, a six-week program that shows you how
0:22.1	healing your body can help you heal your mind. Brain Shaping Academy relies on the same targeted
0:27.6	nutrition and lifestyle strategies that I've used for 30 years to help my patients improve their
0:31.9	mental, emotional, and cognitive health. So if you want to feel calmer, clear, and more in control,
0:37.4	and stay sharp and
0:38.3	protect your brain as you age, check out Brain Shaping Academy at Dr.hyman.com or slash brain shaping.
0:45.0	That's Dr.heimen.com or slash brain shaping. Let me ask you this. If cholesterol were truly
0:51.0	the main cause of heart disease, then why to half the people who have heart attacks have normal LDL levels? And there was a study like 136,000 people who had heart attacks went to ER and 75% had a quote normal LDL level. So that begs the question, then what the hell's going on here? Welcome back to office hours. Over the summer, we're revisiting a few of the conversations that resonated with most of our audience, and this one was at the very top of the list. When this episode first aired,
1:14.8	it sparked a huge response because it challenged something many of us have been told for decades,
1:19.0	and that is this. Cholesterol is the primary driver of heart disease. Well, it might not be
1:24.2	and find out why if you listen. In this conversation, I dive into the latest science around cholesterol and inflammation,
1:30.2	around insulin resistance, and something called APOB, which is super important to know about,
1:34.0	and metabolic health.
1:35.2	And I ask whether we've been focusing on the wrong markers all along.
1:38.9	What's interesting is that since this episode first came out,
1:42.3	the conversation around cardiovascularis has only continued to evolve. And listening back today, many of these insights feel even more relevant than they did the first time. So whether you're hearing about it for the first time or coming back for a second listen, I think you'll walk away with a different perspective on what really drives heart disease risks and what you can do about. Let's get into it. this episode is brought to you by Function Health, empowering you to live 100 healthy years
