The Claim
In hypogonadal men with metabolic syndrome, a 3-month low-carbohydrate diet is associated with a 2.4-point increase in IIEF-5 score, resulting in a shift in erectile function classification from mild-to-moderate to mild dysfunction, while control diets show no significant change in category.
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 men with low testosterone and metabolic syndrome, following a low-carbohydrate diet for three months is linked to a 2.4-point improvement in erectile function scores, moving the condition from mild-to-moderate to mild dysfunction, while other diets do not produce a significant change.

Eating fewer carbohydrates lowers insulin levels, which reduces fat tissue inflammation and allows the testes to produce more testosterone. Less insulin also means less protein binds to testosterone, so more of it is available to act on tissues. Higher testosterone improves blood vessel function in the penis, allowing more nitric oxide to be made, which relaxes muscles and lets blood flow in to create an erection.
What the research says
1 studyMen with low testosterone and metabolic syndrome who ate fewer carbs for three months had better erections, while those who ate normally didn’t improve. This suggests cutting carbs might help their sexual health.
