Our research project aims to investigate the impact of low-carbohydrate diets on cardiovascular health, focusing specifically on the relationship between high levels of low-density lipoprotein (LDL) cholesterol and the risk of cardiovascular events in the absence of other common risk factors. Despite the rising popularity of low-carbohydrate diets for various clinical purposes beyond mere weight loss, there is still limited understanding of their long-term effects on cardiovascular health, particularly when it comes to individuals with isolated high LDL cholesterol levels.
The scientific rationale behind our study stems from the observation that while many studies have highlighted the potential cardiovascular risks associated with high LDL levels, few have examined these risks in individuals following low-carbohydrate diets without considering other confounding cardiovascular risk factors. Our preliminary research, involving a cohort of 548 individuals consuming less than 130 grams of carbohydrates per day, indicated a potential inverse relationship between body mass index (BMI) and changes in LDL cholesterol, prompting further investigation.
The project is set to analyse lipid profiles, dietary patterns, and cardiovascular outcomes among our study participants. We aim to use multivariable survival models, to isolate the effects of LDL cholesterol from other potential risk factors, adjusting for variables like biological sex, age, and serum triglyceride levels to ensure the accuracy of our findings.
Ultimately, our research seeks to clarify whether individuals with high LDL cholesterol but no other cardiovascular risk factors face an increased risk of cardiovascular events when adhering to a low-carbohydrate diet. By providing a more nuanced understanding of these relationships, our findings could have significant public health implications, offering valuable insights for healthcare providers and patients alike regarding the safety and efficacy of low-carbohydrate diets for individuals with specific lipid profiles. This could potentially lead to more personalized dietary recommendations, improving cardiovascular outcomes and overall quality of life for those at risk.
