Which of the following is NOT a risk factor for high cholesterol (HLD)?

Regular exercise is known to have a positive impact on cholesterol levels and overall cardiovascular health. Engaging in physical activity can help raise high-density lipoprotein (HDL) cholesterol, often referred to as "good" cholesterol, while simultaneously lowering low-density lipoprotein (LDL) cholesterol, or "bad" cholesterol. As a result, regular exercise is considered a protective factor against developing high cholesterol rather than a risk factor.

In contrast, obesity, family history, and diabetes mellitus are all established risk factors for high cholesterol. Obesity is associated with increased levels of LDL cholesterol and triglycerides, whereas a family history of hyperlipidemia can increase an individual's genetic predisposition to elevated cholesterol levels. Diabetes mellitus, particularly if not well controlled, contributes to lipid abnormalities, including higher triglycerides and lower HDL cholesterol. Understanding these distinctions helps in managing and mitigating the risks associated with high cholesterol.
