Cholesterol is a fatty substance, but it has no calories.
Cholesterol, fat and saturated fat all circulate in the blood and are deposited on the walls of the arteries. Elevated levels of cholesterol in the blood can lead to coronary artery disease, and puts you at higher risk for developing heart disease. Cholesterol is found ONLY in animal products, like meats, eggs, milk and cheeses. A healthy diet and regular aerobic exercise will lower blood cholesterol levels. LDL's are the BAD cholesterol.
