What is the "ApoB under 80" target — and how hard is it to achieve?

An ApoB below 80 mg/dL is the target associated with the lowest quartile of cardiovascular risk in most large cohort studies, achievable in average-risk men without pharmacological therapy through: LDL-C-reducing dietary changes (saturated fat reduction, soluble fiber increase), visceral fat loss of 5–10% body weight, and right insulin sensitivity, combined these can reduce ApoB by 15–25 mg/dL from an elevated baseline in 3–6 months; men starting above 100 mg/dL typically require statin therapy to reach below 80 mg/dL (Sniderman et al., JAMA Intern Med, 2019).

The 80 mg/dL target applies to average-risk men. High-risk men (prior cardiovascular event, significant family history, diabetes) should target below 65 mg/dL. For reference, the ApoB of a man with perfectly healthy metabolic function throughout his life would be approximately 60–70 mg/dL, the "population average" of 90–95 mg/dL reflects decades of processed food, insulin resistance, and insufficient exercise in most Western male populations.

Honesty Scale: Solid (1) for the ApoB targets based on cardiovascular risk stratification data.

What to do: Test ApoB. If above 80 mg/dL: pursue the lifestyle interventions described above for 3 months, retest, and discuss statin therapy if lifestyle optimization alone is insufficient to reach target.
