A world-first study has found that severely overweight people are less likely to be able to re-wire their brains and find new neural pathways
Pretty interesting stuff and just another reason to keep a healthy weight.
What is a 'world first study ’ ?
One that probably won’t be repeatable (seriously, most scientific results in biomedical research can not be repeated …They languish in the back pile ).
With their statistically TINY study group (15 ‘obese’ and ‘control’ ) and dependence on just one simple and crude experimental method this can safely be thrown on that heap.
Same with how I tried to explain about Vitamin D, you can take condition A and another condition B, and usually find some kind of correlation. Whether that stands up to dozens or hundred of studies is usually the criteria for acceptance.
Exercise has shown in multiple studies to improve Brain plasticity and maintain grey matter as our brain shrink. I don’t think it would be some one off to show that obesity would have negative consequences on the brain.

It’s the first and a small study. That doesn’t mean you should discount it. It’s something worth looking into
One possible reason I can think of is obesity increases inflammation. Inflammation reduces nueroplasticity.
Other reasons could be that such a huge imbalance of fats could negatively impact the brain since we’ve seen plenty of studies show that fatty acids do impact the brain. Omega 3 fatty acids for example, seems to be positive for cognitive ability. Someone with a horrible diet and body fat composition could impact the brain in many ways.
