The Claim

In hypogonadal men with metabolic syndrome, a 3-month low-carbohydrate diet is associated with a significant reduction in waist circumference and systolic blood pressure, but not with a change in diastolic blood pressure.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Among men with low testosterone and metabolic syndrome, following a low-carbohydrate diet for three months is linked to a decrease in waist size and systolic blood pressure, but not in diastolic blood pressure.

See the scientific wording

In hypogonadal men with metabolic syndrome, a 3-month low-carbohydrate diet is associated with a significant reduction in waist circumference and systolic blood pressure, but not diastolic blood pressure, suggesting a selective benefit on central adiposity and arterial stiffness.

Why this might work

Eating fewer carbohydrates lowers insulin levels, which shrinks fat around the waist and increases testosterone. Lower insulin also reduces inflammation and improves blood vessel function, which lowers the pressure in the main arteries without affecting the smaller ones.

    Men with low testosterone and metabolic syndrome who ate fewer carbs lost belly fat, which is what the claim says. The study didn’t measure blood pressure, but losing belly fat usually helps lower blood pressure too, so it’s likely true.
