Studies have shown lower triglyceride levels in those who eat low-carbohydrate diets as compared to those on low-fat diets, according to the National Center for Biotechnology Information. The subjects also maintained healthier levels of both high-density lipoprotein (good cholesterol) and low-density lipoprotein (bad cholesterol).
Many concerns have been raised about low-carbohydrate diets, including less fiber intake and more fat, reports the National Center for Biotechnology Information. However, low-carbohydrate diets have been found to be a safe alternative to low-fat diets for weight loss. The higher intake of protein and foods with a low glycemic index helps to suppress the appetite, making it an effective diet for weight loss.
Studies conducted over the course of a two-year period showed that subjects on a low-carbohydrate diet maintained higher levels of high-density lipoprotein consistently over a longer period of time, according to WebMD. Those on a low-fat diet showed positive results with improving cholesterol levels in the first six months, but the improvement dwindled over the remaining course of the study.
The key diet choices for improving and maintaining healthy triglyceride levels include eliminating sugar, refined foods and alcohol, which increase triglycerides, according to the Mayo Clinic. Additionally, reducing saturated fat and avoiding any foods containing partially hydrogenated oil, or trans fat, helps to manage cholesterol levels.
