Es ist das tiefe viszerale Fett um Organe, das den größten Einfluss auf das Altern des Gehirns hat und die Argumentation, das Gedächtnis und die Verarbeitungsgeschwindigkeit beeinflusst. Dies fügt mehr Beweise dafür hinzu, den Body Mass Index (BMI) – allein nach Gewicht und Größe zu beurteilen – als genaue Marker für die Gesundheit des Gehirns (und im weiteren Sinne).

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:

While we’ve known for some time that obesity affects the brain, scientists have found that, more importantly, it’s where you carry it that matters. And **it’s the deep visceral fat around organs that has the biggest impact on aging your brain, affecting areas of reasoning, memory and processing speed**.

Researchers from The Hong Kong Polytechnic University (PolyU) have used a massive UK Biobank dataset analysis to identify that fat distribution, not just overall size, maps to distinct changes in brain structure and connectivity. And visceral fat stands out as the strongest red flag, linked to poorer reasoning, memory and processing speed. **It adds more evidence to the need to do away with the body mass index (BMI) – judging weight and height alone – as an accurate marker of brain health (and health more broadly)**.

BMI was never meant to be a marker of an individual’s health (though obviously if you have a BMI of 35, you’re not going to be in peak physical condition), but rather a statistical measurement for groups
