So if cholesterol is abnormally high, we really want to focus on reducing inflammation and in turn, your body won't need as much of the bandage and will naturally reduce elevated cholesterol levels (and exercise helps to quickly excrete excess cholesterol). There are multiple factors that can lead to this chronic inflammation:
