Macro partitioning
Ketogenic diets increase the risk of cardiovascular disease markers, specifically LDL-C elevation, which persists even with weight loss, and are associated with increased risks of kidney stones and chronic kidney disease.
Monitor your LDL cholesterol closely if you follow a ketogenic diet, especially if it is high in animal fats. The risk of kidney stones and chronic kidney disease also increases with high animal protein intake.
