&gt; Humans have a <i>physiological</i> aversion to the very idea of eating less, evolution baked it into our bones.<p>I&#x27;m not so sure about this. I recall reading (but can&#x27;t find right now) about some Asian cultures (IIRC) that find eating too much to be unpleasant, as it makes you feel sluggish bodily and slows your thinking down. &quot;Too much&quot; for them being something like what Westerners would consider &quot;satisfied&quot;.
