According to Dayspring (an expert on lipids) the most effective way to lower triglycerides is a low carb diet. By low carb I mean starting at 20 gm/day for a couple of weeks, then gradually adding in a few until weight loss stops. It's the classic Atkins approach, updated. Worked for me, cut mine in HALF in a few weeks. There's a lot of unnecessary worry about very low carb diets out there; they are the most effective for weight loss according to the A to Z trial in 2007 and also had the best results on blood chemistries.
