It would be a good idea to change the way you eat now, before you have any kind of heart attack and have a harder time adjusting. Gymcoach is right also in that it can be simple genetics working against you but a change in diet is always a good idea if you are eating a ton of red meat and fats. If diet alone doesn't cut your numbers enough, there are meds that work well for genetic cholesterol problems. I'm 5'10" and weigh 128, very active, and while in nursing school my cholesterol was high because of the fast food diet I was pretty much forced into by the study schedule I kept. I was able to lower it significantly just with diet alone after nursing school and now have great numbers.
