very good point . I must be at the tip of this evolution branch because i
never been able to make fat despite an enormous appetite all my life.
It give me  a clue about me using up the surplus in a chronic emergency
state ( glucose made available by hypersecretion of cortisone) and going in
hyperactivity. ( before my adrenal cortex colapse.)

My unability to make fat out of the surplus almost killed me too . What is
not a  naturel context ,for instinctive eating is the overabondance of food
all year round, this is  where the intellect can help the instinct to frame
its actions

safe to follow the instinct.
The context  ( set up intellectually) of only undenatured food and of the
naturel seasonal availability of food ( i am a farmer) help me tremendously
to regulate my food intake while following my instinct.
