Con: May Increase Cholesterol Levels
Because the keto diet is so high in fat, you may end up eating tons of saturated fat from bacon, butter, cheese, and fatty meats, which could negatively impact your cholesterol levels.
"You may see your cholesterol levels skyrocket, as all of these are high in saturated fat, which is known to increase unhealthy LDL cholesterol," Brooking told POPSUGAR. Amnon Beniaminovitz, MD of the Medical Offices of Manhattan, added that this is particularly problematic for people who have heart disease risk factors.
If you want to try the keto diet, Dr. Beniaminovitz advised, "You should have your cholesterol checked routinely and be followed by a cardiologist or a endocrinologist that can modify the diet and help minimize the risks."
