This is another controversial common keto question. Keto might raise total cholesterol a little, but it will mostly raise your good cholesterol (HDL). More than likely it will also lower triglycerides, blood pressure, and A1C (blood sugar). Additionally, Keto has also been shown to improve liver function tests and lower inflammation. Inflammation oxidizes the cholesterol (which is bad). It (inflammation) is measured by a C-Reactive Protein Test. This scientific study titled: "Comparison of C-reactive protein and low-density lipoprotein cholesterol levels in the prediction of first cardiovascular events," suggested that: "The C-reactive protein level is a stronger predictor of cardiovascular events than LDL cholesterol."
