What lifestyle change is crucial for patients with high cholesterol levels?

Increased physical activity is a crucial lifestyle change for patients with high cholesterol levels because it directly influences lipid profiles and overall cardiovascular health. Engaging in regular physical activity can help raise high-density lipoprotein (HDL) cholesterol, which is often referred to as the "good" cholesterol, while simultaneously lowering low-density lipoprotein (LDL), or "bad" cholesterol, and triglycerides. Furthermore, physical activity contributes to weight management, which is vital for those dealing with elevated cholesterol. Other benefits of increased exercise include improved circulation, better heart function, and reduced risk of heart disease.

In contrast, increased alcohol consumption does not benefit cholesterol levels and can actually lead to further health complications. A high-protein diet may vary significantly in compositions and sources, and some may be unhealthy depending on the types of proteins consumed. Smoking cessation plays a vital role in overall heart health but does not specifically target cholesterol levels in the same direct way as physical activity. While all these factors are important for cardiovascular health, increased physical activity is particularly effective in managing high cholesterol directly.
