Übergewichtige Menschen hatten ein um 14% geringeres Risiko für die Entwicklung von Demenz im Vergleich zu Menschen mit normalem Gewicht, während übergewichtige Teilnehmer ein geringeres Risiko von 19% hatten. Diejenigen, die von der Lebensmitte bis zum späten Leben abgenommen haben, hatten jedoch ein erhöhtes Risiko für Demenz. Dies ist das sogenannte Paradoxon der Fettleibigkeit.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:

A longitudinal study of more than 5,000 older adults revealed that individuals classified as **overweight had a 14% lower risk of developing dementia compared to those with normal weight, while obese participants had a 19% lower risk. However, further analysis indicated that individuals who lost weight from midlife to late life had an increased risk of dementia**. Those whose weight remained stable had the lowest risk. The paper was published in Neurology.

The findings suggest that the **so-called obesity paradox** may be at least partly explained by unintentional weight loss associated with underlying health decline. The study could not determine whether weight loss was intentional or unintentional. Unintentional weight loss is common in older adults and is often a sign of deteriorating health. In such cases, both weight loss and cognitive deterioration can be the consequence of a decline in physical health.
