Auriel Willette and Brandon Klinedinst of Iowa State University discovered people mostly in their 40s and 50s who had higher amounts of fat in their mid-section had worse fluid intelligence as they got older.

These relationships stayed the same even after taking into account chronological age, level of education, and socioeconomic status.

• Adiposity exacerbated cognitive aging.
• Greater muscle mass was protective against cognitive aging.
• The effect of muscle on cognition was more than adiposity.
• Lymphocytes, eosinophils, and basophils may link adiposity to cognitive outcomes.
• Sex-specific mechanisms of action were noted among eosinophils and basophils.

Also, Intermittent fasting could be added to medical school curricula alongside standard advice about healthy diets and exercise.
