how obesity can increase intelligence

8.8: health/cortisol confusion:

. I had thought that cortisol

was the source of greater success among the obese,

but now I'm thinking the relation is like this:

. adrenalin dips sugar which raises cortisol

that causes insulin resistance;

and then adding grain diet to that condition

raises insulin, which raises inteligence .

[ cortisol does raise blood sugar for the brain's benefit,

but I was confused at how

increases of this could both increase intelligence

and be the source of brain damage ] .
