Scientists Find Link Between Excessive Body Fat and a Smaller Brain

If it seems like your clothes are shrinking, it could be that you’ve gained weight and your clothes aren’t really shrinking. But researchers have found that something even more important may be shrinking due to excess body fat – your brain.
It seems that having excessive body fat around the middle can lead to brain shrinkage, according to recent research. Specifically, shrunken gray matter volume. Gray matter contains the brain’s 100 billion nerve cells. The brain’s white matter contains the nerve fibers necessary for connecting brain regions.
