The Claim

Low and very-low carbohydrate diets (<40% energy from carbohydrates) lead to greater reductions in triacylglycerol (TAG) concentrations compared to moderate-low carbohydrate diets, with average decreases of −0.18 mmol/L and −0.27 mmol/L respectively, indicating a more favorable improvement in this cardiometabolic risk marker with stricter carbohydrate restriction.

Support is ahead, but a single strong opposing study can change this.

In plain English

Eating fewer carbs—especially very low amounts—seems to lower blood fat levels more than eating a little more carbs, which might be better for heart health.

See the scientific wording

Triacylglycerol (TAG) concentrations decrease more significantly with low and very-low carbohydrate diets (<40% energy from carbs) than with moderate-low carbohydrate diets, with reductions averaging −0.18 mmol/L and −0.27 mmol/L respectively, suggesting greater improvement in this cardiometabolic risk marker with stricter carbohydrate restriction.

  1. Study: The Effects of Different Degrees of Carbohydrate Restriction and Carbohydrate Replacement on Cardiometabolic Risk Markers in Humans—A Systematic Review and Meta-Analysis

    The study looked at how different low-carb diets affect blood fat levels, and found that stricter low-carb diets lower triglycerides more than milder ones, which supports the claim.
