Which lifestyle change is likely to raise HDL levels?

Regular exercise is known to be one of the most effective lifestyle changes for raising high-density lipoprotein (HDL) levels, which is often referred to as "good" cholesterol. HDL cholesterol plays a protective role in heart health by helping to transport cholesterol away from the arteries and back to the liver, where it can be processed and eliminated from the body. Engaging in aerobic exercises, such as walking, running, cycling, or swimming, has been shown to positively influence HDL levels, making this option the best choice for promoting cardiovascular health and improving lipid profiles.

In contrast, increased sugar intake, increased saturated fat intake, and weight gain tend to have negative effects on lipid levels. High sugar intake can lead to higher triglyceride levels and lower HDL, while consuming saturated fats is generally associated with increased low-density lipoprotein (LDL) levels rather than raising HDL. Weight gain, particularly if it leads to obesity, is also correlated with lower HDL levels, which would be detrimental to cardiovascular health. Therefore, exercise stands out as the most favorable change for increasing HDL levels.
