Sorry I think we agree!  My point is it is a psychological issue.  All things being equal (calories, nutrients etc.) the speed&#x2F;magnitude of the insulin response is not important for overall health (in the non-diabetic population).  The study mentions things like:<p>&gt;  postmeal blood glucose and its long-term metabolic consequences.<p>and the point is there aren&#x27;t long term <i>metabolic</i> consequences.<p>&gt; but if we can put a finger on exactly what causes people to put on a few pounds it would be a significant advance in science that would affect billions of people<p>I totally agree!  We know it&#x27;s not the insulin response in and of itself that is causing weight gain, it&#x27;s the subsequent increased caloric intake, so my point is by being deliberate about what we are studying we can get better results.  I&#x27;m not saying we don&#x27;t need to study the psychology of eating, definitely the opposite!  That&#x27;s really what we need to focus on, and stop worrying about the &quot;metabolic consequences&quot; of the insulin response.
