The Claim
In hypogonadal men with metabolic syndrome, a 3-month low-carbohydrate diet is associated with a 2.4-point improvement in IIEF-5 erectile function scores, reducing the severity of erectile dysfunction from mild-to-moderate to mild, independent of changes in body weight or blood pressure.
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.
Among men with low testosterone and metabolic syndrome, following a low-carbohydrate diet for three months is linked to a 2.4-point increase in erectile function scores, resulting in a reduction of erectile dysfunction severity from mild-to-moderate to mild, regardless of changes in body weight or blood pressure.

Eating fewer carbohydrates lowers insulin levels, which reduces fat tissue inflammation and allows the testes to make more testosterone. Less insulin also means less protein binds to testosterone, so more of it is available to act on the body. Higher testosterone improves blood vessel function in the penis, and lower fat and better blood sugar help blood vessels produce more nitric oxide. This opens up blood vessels in the penis, allowing more blood to flow in and maintain an erection.
What the research says
1 studyMen with low testosterone and metabolic syndrome who ate fewer carbs for three months had better sexual function, and their testosterone levels went up—even though they also lost some weight. The study suggests the diet itself helped, not just the weight loss.
