We have heard it all - exercising helps reduce bad cholesterol (LDL), but how? Exercising helps maintain a healthy body weight, which decreases the amount of Low Density Lipoprotein, LDL, in blood. Second, exercising stimulates enzymes that move LDL to liver, which convert cholesterol to bile for digestion or excrete it. In addition, exercising increases the size of protein particles that carry cholesterol. As protein particles get bigger, they don’t squeeze into linings of heart or blood vessels and create clogs that lead to heart diseases. Doctors, trainers, and medical researchers recommend exercising moderately 30 minutes a day everyday.
