How does a low-carb diet affect cholesterol levels?

In a two-year trial, LDL Cholesterol rose 5%–10%, while other blood fat measures improved or stayed steady. The study compared a Low-Carb Diet high in saturated fat with two lower-fat diets. People eating the other diets ate more Carbohydrates, mainly from whole grains. The higher-fat group cut out most grains. The provided report does not give the group sizes or ages. The standout finding involved Apolipoprotein B (ApoB), a marker of cholesterol-carrying particles in blood. It did not rise or change much differently across the diets. Meanwhile, LDL Cholesterol increased, mainly through larger cholesterol-carrying particles. Smaller, denser particles did not change much. Other results moved in a more favorable direction. Triglycerides, a type of blood fat, fell by 20%–35% in the higher-fat group. HDL Cholesterol, often called “good” cholesterol, rose by 5%–18%. These two measures stayed fairly unchanged on the other diets. These mixed results do not settle the long-term health question. The researchers stressed that the cholesterol rise cannot simply be dismissed. Larger particles do not prove that the increase is harmless. More research is needed to understand what these changes mean together. For BioSocial members, this highlights the value of comparing several bloodwork results. One improved number may not tell the whole story. Tracking results alongside food choices and dates can make community comparisons clearer. This study tested a specific higher-saturated-fat eating pattern, not every way of eating fewer carbs. What changes have you seen in your bloodwork after cutting carbs, and how did your food choices change?
