HDL cholesterol plays a key role in cholesterol metabolism by helping your body either recycle or get rid of it (27, 28).
Higher HDL levels are linked to a reduced risk of heart disease (29, 30, 31).
One of the best ways to raise HDL is to increase dietary fat intake on a low-carb or ketogenic diet (16).
As you can see in the graph above, a ketogenic diet can cause a major increase in HDL levels (16).
Bottom Line: HDL (the “good”) cholesterol plays a key role in cholesterol metabolism, and is linked to a reduced risk of heart disease. A ketogenic diet can cause a big increase in HDL levels.
