Understanding Cholesterol and Its Importance

Cholesterol represents a type of lipid vital for cell membrane integrity, hormone synthesis, and vitamin D production. Your body produces cholesterol naturally through the liver, but you also absorb it from animal-derived foods. Lipoproteins transport cholesterol in your blood as either low-density lipoprotein (LDL) or high-density lipoprotein (HDL). LDL carries cholesterol to tissues, which, if elevated, often causes plaque buildup in arteries. HDL removes excess cholesterol, transporting it to the liver for excretion.

Blood cholesterol measurements show correlations with heart disease risk. Elevated LDL cholesterol increases atherosclerosis risk, while low HDL levels associate with higher cardiovascular events. Standard metrics include total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides, representing types of fats in blood. Advanced testing further explores particle number and size, which, according to Dr. Peter Attia, offer a more comprehensive heart health profile.

Peter Attia’s Philosophy on Cholesterol Testing

Peter Attia prioritizes advanced cholesterol testing to assess cardiovascular risk more accurately than standard lipid panels. You find that his approach shifts focus from basic measures like total cholesterol or calculated LDL to direct measurement of atherogenic particle numbers. He emphasizes the use of ApoB and LDL-P as primary markers, both shown in research to predict atherosclerotic cardiovascular disease (ASCVD) more reliably than LDL-C or non-HDL cholesterol [JAMA Cardiol. 2022;7(8):858-862].

You see Attia recommend expanding routine cholesterol assessment with additional metrics. Examples include lipoprotein(a), which independently raises ASCVD risk even with normal cholesterol, and triglyceride-rich lipoprotein particles like VLDL, which reflect metabolic health. He considers insulin resistance and inflammatory markers such as hsCRP for a comprehensive risk profile.

You gain actionable insight from Attia’s philosophy, which centers on frequent, individualized testing over time rather than one-off measurements. He advocates trend analysis, helping detect early changes and guiding interventions for longevity-focused heart disease prevention.

Core Cholesterol Tests Peter Attia Recommends

Peter Attia recommends a panel of core cholesterol tests to achieve a more accurate cardiovascular risk assessment. These advanced measurements deliver nuanced data beyond conventional lipid screening.

Lipid Panel

Attia includes the lipid panel in every cholesterol workup. Panel results report total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. Total and LDL cholesterol values reflect the amount of cholesterol circulating in low-density lipoproteins, while HDL cholesterol represents cholesterol in high-density lipoproteins. Triglyceride levels supply information on the presence of remnant particles implicated in atherogenesis. Attia interprets standard lipid panel metrics in context, correlating results with particle-based markers to generate individualized risk profiles.

ApoB Test

Attia places special emphasis on apoB testing. The apolipoprotein B test quantifies the number of atherogenic lipoprotein particles such as LDL, VLDL, IDL, and Lp(a). Each atherogenic particle contains exactly one apoB molecule, which makes apoB a direct proxy for total atherogenic burden. Elevated apoB levels correlate strongly with coronary artery disease risk, outperforming LDL cholesterol in risk discrimination, according to JAMA Cardiology (Sniderman et al, 2019). Attia prioritizes apoB over LDL-C in longitudinal monitoring and intervention planning.

LDL-P (LDL Particle Number)

Attia uses LDL particle number, or LDL-P, as an advanced metric. LDL-P provides a direct count of LDL particles, which can vary independently from the cholesterol carried within those particles. Nuclear magnetic resonance (NMR) spectroscopy enables LDL-P measurement. Research from the Multi-Ethnic Study of Atherosclerosis (Otvos et al, 2011) shows increased cardiovascular event risk correlates better with high LDL-P than with high LDL cholesterol. Attia recommends routine inclusion of LDL-P, particularly for those with discordant LDL-C and apoB levels.

Lp(a) Test

Attia includes lipoprotein(a), or Lp(a), measurement for comprehensive risk evaluation. Lp(a) is a genetically determined cholesterol-rich particle that independently increases atherosclerosis risk. Levels above 30 mg/dL signify significant vascular risk, based on Circulation (Tsimikas et al, 2018). Lp(a) does not respond to diet or most lipid-lowering drugs; recognizing elevated levels helps stratify lifetime cardiovascular risk and informs decisions about early interventions and family member testing.

Inflammation Markers

Adding inflammation markers enhances cardiovascular risk prediction. The hs-CRP assay measures high-sensitivity C-reactive protein, identifying low-grade vascular inflammation linked with higher atherosclerosis risk (Ridker et al., NEJM 2002). Attia routinely includes hs-CRP in comprehensive lipid evaluations, especially for those with multiple risk factors or unclear risk levels. Some assessments also incorporate GlycA, quantifying inflammation-related glycoproteins, and Lp-PLA2, indicating vascular plaque activity. Elevated levels signal increased probability of future cardiovascular events, even when cholesterol appears controlled.

Advanced Lipoprotein Analysis

Expanding beyond basic cholesterol, advanced lipoprotein analysis quantifies particle properties that standard panels miss. An NMR (nuclear magnetic resonance) lipid profile delivers direct particle counts and sizes for LDL, HDL, and VLDL, providing a granular portrait of atherogenic risk independent of cholesterol content. Attia prefers apolipoprotein-based markers—especially apoB for all atherogenic particles and apoA1 for cardio-protective HDL subsets—alongside LDL-P, VLDL-P, and HDL size distribution. This multi-dimensional approach pinpoints hidden risk in those with "normal" cholesterol and guides aggressive prevention for those at higher risk from inherited or metabolic causes.

How Often Should You Get Tested?

Testing frequency matters for accurate cardiovascular risk detection, according to Dr. Peter Attia. He suggests baseline advanced cholesterol tests for adults age 18 or older, before risk factors or symptoms emerge. People with high-risk traits—such as family history of heart disease, elevated lipoprotein(a), insulin resistance, or metabolic syndrome—benefit from annual testing. Those without significant risk factors may repeat advanced lipid panels and particle number assessments every 3 to 5 years, if earlier results were normal.

Trend evaluation over time offers better insight than a single blood draw, so schedule testing at consistent intervals. If you start or adjust diet, exercise, or medication, check updated cholesterol and ApoB numbers within 3 to 6 months to see if interventions are effective. Always discuss exact intervals with your healthcare provider for a plan tailored to your personal risk profile and health changes.

How to Discuss These Tests With Your Doctor

Approach your doctor with preparation when considering Dr. Peter Attia's cholesterol testing recommendations. Bring a complete list of your personal risk factors, including family history of cardiovascular disease, past lipid panel results, and any metabolic or inflammatory conditions. Reference authoritative terms like ApoB, LDL-P, and lipoprotein(a), as these specific markers increase clarity in medical discussions about particle-based cholesterol risk assessment.

Ask your doctor for advanced lipid testing if standard panels don’t provide enough data about your heart health. Request specific tests—such as apoB, LDL-P, Lp(a), triglyceride-rich particles, and hs-CRP—and clarify your reasons by explaining their association with atherosclerotic risk, as supported by research (JAMA Cardiology, 2021; Circulation, 2018).

Discuss test frequency with your provider, noting Dr. Attia’s guidance on trend evaluation and individualized retesting plans. Use your previous results to support requests for annual or biannual evaluations if you’re at high risk, or every 3–5 years if you’ve had low-risk findings.

Clarify the purpose and actionability of each test result. Ask for interpretation in context with your full risk profile—address how advanced metrics can change your personal prevention strategy or inform early intervention.

If your provider’s unfamiliar with a test, present curated sources or guidelines—such as those from the National Lipid Association or American Heart Association—to support your request and ensure an evidence-based approach.
