"There isn't a drug that lowers triglyceride levels well, which is why mainstream medical doctors don't pay much attention to them. But triglycerides respond very strongly to dietary changes. If you reduce your carbohydrate intake, you tend to have ideal triglyceride levels, in the 50 to 60 range. Additionally, the triglyceride-to-HDL ratio is a good indicator of how well your diet is dialed in. If the ratio is high, you might benefit from eating more saturated fats and fewer carbs."
