LDL cholesterol-lowering drugs reduced overall mortality by 20% in high-risk patients without a history of heart attack or stroke.

Deeply lowering low-density lipoprotein cholesterol may not only prevent a first heart attack or stroke, but may also potentially be associated with increased life expectancy in patients at very high cardiovascular risk.

According to clinical studies, the keto diet has more health benefits than other popular weight loss diets.
