The Claim
After 16 weeks of a low-carbohydrate diet compared to usual care, there were no statistically significant changes in New York Heart Association (NYHA) functional class in patients with diabetic cardiomyopathy.
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 for 16 weeks did not result in a measurable improvement in heart failure severity as assessed by the NYHA functional class compared to standard care.
See the scientific wording
No statistically significant changes were observed in New York Heart Association (NYHA) functional class in patients with diabetic cardiomyopathy after 16 weeks of a low-carbohydrate diet compared to usual care, indicating the diet did not improve objective heart failure severity.
Eating fewer carbs lowers insulin and makes the body burn fat for fuel, producing ketones that the heart can use instead of sugar. This reduces fat buildup and fluid retention, but the heart's muscle remains stiff and cannot fill properly with blood, so heart failure symptoms do not improve.
What the research says
1 studyThe study found that eating fewer carbs didn't make people with diabetic heart failure feel any better or improve their heart failure classification after 16 weeks, even though they lost weight. So, the diet didn't help their heart failure symptoms as measured by doctors.
