I eat a very clean anti-inflammatory diet. Why is my hs-CRP still elevated?

Because the anti-inflammatory diet claim is substantially overstated when it is not accompanied by meaningful visceral fat reduction. Dietary quality changes alone, without a change in body composition, typically reduce hs-CRP by 0.2–0.5 mg/L. A man with an hs-CRP of 4.5 who adopts a Mediterranean diet and maintains his waist circumference will likely have an hs-CRP of 4.0–4.3 mg/L six months later. This is measurable improvement, not transformation.

The most powerful single lifestyle lever on hs-CRP is visceral fat loss, approximately 1–3 mg/L reduction per 5 kg of fat mass lost. If your diet is clean but your waist circumference is unchanged, you have improved dietary quality without addressing the primary driver. The second and third most commonly missed drivers in clean-eating men are obstructive sleep apnea (which many fit, health-aware men have undiagnosed) and periodontal disease (which has no dietary fix). If your diet is genuinely anti-inflammatory and your hs-CRP persists above 2.5 mg/L, these two deserve immediate investigation. (Pannacciulli et al., International Journal of Obesity, 2001)

Cardiologist's calibrated position, Promising (2) for Mediterranean diet effects on hs-CRP. The effect size is modest without weight change.

What to do: Get a STOP-BANG questionnaire score for sleep apnea risk. Schedule a dental evaluation specifically for periodontal pocket depth measurement. Get a fasting insulin to check for insulin resistance that dietary change has not fully resolved.
