Macro partitioning

A very-low-carbohydrate ketogenic diet (VLCKD) significantly improves triglycerides (TAG) and diastolic blood pressure (DBP) compared to a low-fat diet (LFD) over the long term, but also increases LDL-C and HDL-C levels.

Switching to a very-low-carb diet improves triglycerides and blood pressure more than a low-fat diet, but it will raise your LDL and HDL cholesterol. Discuss these changes with your doctor, as the increase in LDL may be less harmful than traditionally thought due to particle size changes.
