The Brain Is Built on Water

In your book, you talk about the fact that the brain's probably only about 11% fat. Even just a 2% water loss in the brain can cause neurological symptoms like fatigue, dizziness, confusion, brain fog. If you are dehydrated, your brain literally shrinks and you don't want your brain to shrink. We have to replenish this water constantly because the body doesn't produce it on its own.
