Statin therapy is not warranted for a person with high LDL-cholesterol on a low-carbohydrate diet.
Study Goal
The researchers aimed to assess the cardiovascular disease (CVD) risk associated with low-carbohydrate diets (LCD), particularly focusing on LDL-C levels, and evaluate whether statin therapy is necessary for individuals on LCD with elevated LDL-C.
Results Summary
The study found that LCD is safe and effective, improving robust CVD risk factors like hyperglycemia, hypertension, and atherogenic dyslipidemia, while also demonstrating that LDL-C is ineffective in predicting CVD risk. Statin therapy was deemed unnecessary for individuals on LCD with elevated LDL-C if they achieved a low triglyceride/HDL ratio.

PURPOSE OF REVIEW: Although there is an extensive literature on the efficacy of the low carbohydrate diet (LCD) for weight loss and in the management of type 2 diabetes, concerns have been raised that the LCD may increase cardiovascular disease (CVD) risk by increasing the level of low-density lipoprotein cholesterol (LDL-C). We have assessed the value of LDL-C as a CVD risk factor, as well as effects of the LCD on other CVD risk factors. We have also reviewed findings that provide guidance as to whether statin therapy would be beneficial for individuals with high LDL-C on an LCD. RECENT FINDINGS: Multiple longitudinal trials have demonstrated the safety and effectiveness of the LCD, while also providing evidence of improvements in the most reliable CVD risk factors. Recent findings have also confirmed how ineffective LDL-C is in predicting CVD risk. SUMMARY: Extensive research has demonstrated the efficacy of the LCD to improve the most robust CVD risk factors, such as hyperglycemia, hypertension, and atherogenic dyslipidemia. Our review of the literature indicates that statin therapy for both primary and secondary prevention of CVD is not warranted for individuals on an LCD with elevated LDL-C who have achieved a low triglyceride/HDL ratio.
