The Claim
A low-carbohydrate diet was associated with a large standardized effect size (Hedges’s g = 0.99) for systolic blood pressure reduction compared to usual care in patients with diabetic cardiomyopathy, though the difference was not statistically significant (p=0.39), indicating a potential trend that requires further investigation.
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.
In patients with diabetic cardiomyopathy, a low-carbohydrate diet was linked to a large average reduction in systolic blood pressure compared to usual care, but the difference was not statistically significant.

Eating fewer carbohydrates lowers insulin levels, which causes the kidneys to release more salt and water, reducing blood volume and pressure. At the same time, the heart switches to using ketones for energy instead of sugar, which reduces stress on heart muscle and improves its function.
What the research says
1 studyPeople with diabetic heart problems who ate fewer carbs tended to have lower blood pressure than those who ate normally, but the group was too small to be 100% sure it wasn’t just luck. More research is needed to confirm it.
