The Claim

In obese adults, a three-month ketogenic diet is associated with a reduction in impulsivity on the urgency subscale, while a three-month Mediterranean diet is not associated with a significant change in impulsivity on the urgency subscale.

In plain English

Obese adults who follow a ketogenic diet for three months show lower impulsivity on the urgency subscale compared to those who follow a Mediterranean diet, which shows no change in impulsivity.

See the scientific wording

In obese adults, a three-month ketogenic diet is associated with a reduction in impulsivity, specifically in the urgency subscale, while the Mediterranean diet shows no significant change, suggesting differential effects on behavioral control.

Why this might work

Eating a ketogenic diet changes the bacteria in the gut, which produce more taurine and threonine. These chemicals enter the brain and change how nerve cells communicate in areas that control sudden urges, making people less likely to act on impulse.

  1. Study: Ketogenic diet is less effective in ameliorating depression and anxiety in obesity than Mediterranean diet: A pilot study for exploring the GUT-brain axis.

    In obese adults, eating a keto diet for three months was linked to less impulsive behavior — especially acting on sudden urges — while the Mediterranean diet didn’t have this effect. The study found this difference directly in people.
