We thank Ravnskov [1] for his interest in our recent publication [2]. In our study, low-density lipoprotein cholesterol (LDL-C) and Apolipoprotein B-100 (ApoB) almost doubled in young, healthy women when they followed the ketogenic low-carbohydrate high-fat (LCHF) diet. According to the European Society of Cardiology (ESC) and the European Atherosclerosis Society (EAS) Guidelines for the management of dyslipidaemias [3] “…there is no longer an ‘LDL-C hypothesis’, but established facts that increased LDL-C values are causally related to atherosclerotic cardiovascular disease, and that lowering LDL particles and other ApoB-containing lipoproteins as much as possible reduces cardiovascular events.” Therefore, we think it is reasonable to conclude that the alterations in blood lipids reported in our study should be a cause for concern in young women following this kind of LCHF diet.
