Triglycerides fall 30-50% on keto — a strong, independent cardiovascular risk factor. HDL consistently rises. LDL particle quality shifts from small, dense (high-risk) to large, buoyant (low-risk). Systemic inflammation markers fall. The Triglyceride:HDL ratio — one of the best single cardiovascular predictors — dramatically improves on keto. Our keto main dishes featuring fatty fish and our keto salads with olive oil provide cardiovascular-protective nutrition.
