A short-term ultra-processed diet increased liver fat by 63% without changing body weight, altered brain insulin activity, and diminished reward sensitivity and white matter integrity.

“A new study found that just 5 days on a high-calorie ultra-processed diet led to: - A 63% increase in liver fat, despite no change in body weight. - Altered insulin activity in the brain, impairing metabolism. - Diminished reward sensitivity and reduced white matter integrity in regions controlling motivation, cognition, and impulse control.”
