Effects Of N 3 Polyunsaturated Fatty Acids (ω 3) Supplementation On Some Cardiovascular Risk Factors With A Ketogenic Mediterranean Diet

This study examined whether adding omega-3 fatty acid supplements (the healthy fats found in fish oil) could boost the cardiovascular benefits of a ketogenic Mediterranean diet. Researchers followed 34 overweight men aged 25-65 for four weeks, with half following the diet alone and half adding omega-3 supplements to their regimen.

Both groups experienced significant weight loss (about 4-5 kg) and improvements in key health markers including total cholesterol, LDL ("bad") cholesterol, and blood sugar levels. However, the group taking omega-3 supplements showed additional benefits that the diet-only group didn't achieve. Specifically, they had greater reductions in triglycerides and insulin levels, and more comprehensive improvements in inflammation markers throughout their bodies.

The omega-3 group also saw increases in adiponectin, a beneficial hormone that helps regulate metabolism and reduces inflammation. Most notably, while both groups showed some reduction in inflammatory proteins, the omega-3 group had decreases across multiple inflammation markers, suggesting better overall anti-inflammatory effects.

This research suggests that combining omega-3 supplementation with a well-formulated ketogenic approach may provide superior metabolic and cardiovascular benefits compared to dietary changes alone. At VALIA Health, this type of evidence helps inform personalized nutrition strategies that optimize both weight management and long-term cardiovascular health through targeted supplementation alongside dietary interventions.
