Ketogenic diet

Definition

A ketogenic diet is a high-fat, low-carbohydrate dietary regimen that induces ketosis, a metabolic state in which the body uses fat as its primary energy source. It has been studied for its effects on lipid profiles and potential benefits in managing certain health conditions.

5 Must Know Facts For Your Next Test

1. The ketogenic diet can significantly increase levels of high-density lipoprotein (HDL) cholesterol.
2. Low-density lipoprotein (LDL) particle size tends to increase on a ketogenic diet, which may reduce cardiovascular risk.
3. Triglyceride levels often decrease substantially when following a ketogenic diet.
4. The production of ketone bodies from fatty acids occurs during ketosis and provides an alternative energy source for cells.
5. The long-term effects of the ketogenic diet on overall cardiovascular health are still under investigation.
