There are many reasons that are thought to contribute to brain shrinkage .....normal aging first and foremost.....chronic back pain is thought to bring about brain size reduction, as well as alcohol, Internet addiction, lack of sunlight, sleeplessness, and people not getting enough vitamin B 12.....that might be people who have a vegetable heavy diet and don't get this vitamin in their food or with supplementation.

You remember correctly. The brain is about 78% water, 12% fat, and 8% protein. And it's true that there are other ways of bringing about brain shrinkage. But my question still stands: Would dieters experience brain shrinkage as they lose body fat?
I disregarded water because I was thinking in terms of solids. It seems that fat is the largest solid component. Is that not correct? I'll edit my first post.
