"Our data show that fasting induces an anti-inflammatory effect on a
lean animal's neuroimmune system, and that effect is inhibited by a
high-fat diet," Gregory G. Freund, MD, of the University of Illinois in
Urbana, said in a statement. "Some of the brain-based chemical changes
that occur in a lean animal simply don't occur in an obese animal."

This part is strange. The reduced water retention of ketotic plans tend
to reduce inflamation and ketotic plans tend to be high fat. I don't
think they have a low carb set of test subjects.
