Emerging evidence shows that insulin resistance is the most important predictor of cardiovascular disease and type 2 diabetes.

Aggressive lowering of low-density lipoprotein cholesterol (LDL-C) has been the cornerstone of preventative cardiology for decades. Statins are widely used as the go-to solution for the prevention of heart disease owing to their ability to slash LDL-C levels, a ‘surrogate marker’ of cardiovascular disease (CVD). Indeed, statins are one of the most widely prescribed class of drugs in the world. But this phenomenon begs two questions: is the enthusiasm for aggressive lowering of LDL-C justified; and is pharmacotherapy superior to lifestyle intervention?

Over the years, medical guidelines have continually expanded the number of individuals for whom statin therapy is recommended. Proponents argue that statins are ‘life-savers’ and that ‘people will die’ if they discontinue their medicine[1],[2]. Prominent researchers from reputable universities have declared that ‘everyone over 50’ should be on a statin to reduce their risk of CVD and that even children with high LDL-C as young as 8 years should be afforded statin therapy[3].
