To reduce high cholesterol levels quickly, the individual should use prescribed medication, exercise, avoid foods high in saturated fats, eat foods rich in fiber and omega-3 fatty acids, and replace soft drinks with green tea, claims WebMD. Poor diets and lifestyle habits can raise bad low-density lipoprotein cholesterol levels.
Healthy lifestyle choices lower high cholesterol levels at a moderate pace, but if an individual's levels are too high, these choices may not work fast enough, according to Dr. Michael Richman. Because of this, the most effective way to lower dangerous levels of cholesterol is to take a cholesterol-lowering medication, such as niacin, bile acid resins, fibrates and statins, the latter of which may reduce LDL cholesterol levels by as much as 50 percent.
High but not yet dangerous cholesterol levels may be reduced to safe levels quickly through exercise and a healthy diet, as stated by WebMD. Exercise may even raise good high-density lipoprotein cholesterol levels by 10 percent. Individuals are recommended to introduce regular activity into their lifestyles by exercising at least five days each week.
While individuals should consider cutting back on cholesterol-rich foods, new research suggests that foods high in saturated fats may be much bigger culprits in raising LDL cholesterol levels, according to WebMD. As such, butter and other oil-rich foods must be avoided as well.
