FWIW, my triglycerides were in the very high range before I developed diabetes (>1000mg/dL). That was about 10 years ago, when I was in much better physical shape, doing plenty of strength training and cardio, etc. That was...an unwelcome surprise. Talking with the doctor, her opinion was that there was basically nothing more I could really do in terms of diet and exercise, so she put me on Lopid, and later once diabetes hit, Lipitor. Both were quite effective in pushing my triglycerides and cholesterol into the normal range.
