The Claim
Low-carbohydrate diets increase HDL cholesterol concentrations by an average of 0.08 mmol/L compared to moderate-carbohydrate diets, with greater increases observed when carbohydrates are replaced with fats or proteins, although the clinical significance of this change is uncertain due to concurrent increases in LDL cholesterol.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating fewer carbs might raise your 'good' cholesterol a little, especially if you replace them with fats or proteins, but it could also raise your 'bad' cholesterol, so it's not clear if this is truly helpful for your heart.

Low-carbohydrate diets increase HDL cholesterol concentrations by an average of 0.08 mmol/L compared to moderate-carbohydrate diets, with greater increases observed when carbohydrates are replaced with fats or proteins, though the clinical significance of this change remains uncertain due to concurrent increases in LDL cholesterol.
What the research says
1 studyThe study shows that cutting carbs raises 'good' cholesterol, especially when replaced with fat, which matches the claim. It also notes a rise in 'bad' cholesterol, so the overall heart benefit isn't clear.
