Hello xanga,
Your cholesterol results are not bad at all, provided that you do not have heart disease or other risk factors for heart disease.
Diet, exercise, and genetics are the three important factors that determine your cholesterol profile. Exercising 4 times a week for 40 minutes even if you are not overweight is an important way to improve your cholesterol levels. Also, if you want to lower your LDL and raise your HDL, you could increase the amount of fiber in your diet by eating whole grains, legumes, fruits and vegetables. Consider trying to eat fish high in omega-3 fatty acids at least twice a week.
Some people, regardless of the intensity of their diet or exercise regiments, have a genetically high cholesterol. This is especially true if your family memebers have high cholesterol, too.
Be sure to continue to monitor your lipid profile with your physician and inform him of your lifestyle modifications!
To your health,
Neil MD
