6. It Can Help Lower Triglyceride Levels

Blood triglycerides are an important marker of heart health, and describe the amount of fat in your blood. High levels are linked to an increased risk of heart disease (24, 25).
The increased risk can be as high as 30% in men, and 75% in women (26).
This study found that a ketogenic diet lowered fasting triglyceride levels by 44%, while no change was found with the low-fat, high-carb diet (24).
Additionally, the amount of fat in the blood after meals was significantly reduced, as shown in the graph above.
The ketogenic diet also improved other markers of metabolic syndrome. For example, it caused more weight loss, decreased the triglyceride:HDL ratio and reduced blood sugar levels (24).
Bottom Line: Despite a very high fat content, the ketogenic diet can cause massive reductions in blood triglyceride levels.
