I don't have access to the Nature article, but on the face of it these concerns seem ridiculous. Perhaps they hold for some extreme (perhaps those very high saturated fat, zero vegetable) lo-carb diets, with extreme ketosis for very long terms. On the contrary, I associate heart arrhythmias and heart muscle problems with low calorie high carb diets, which are known to casue weight loss in part by attacking muscle, including heart muscle, tissue: e.g., the dangers of death from prolonged fasting (even "juice" fasting). I'm interested to hear from our more scholarly list members. John Blank, L.Ac.
