And it makes DUH!!! Common sense. This why calorie counting models (which do work if done right) are inferior. 

So long as you have valid and good Satiety Index Score data (which can be improved over time), this is a may superior metric. 

If you predominately eat foods you both like and are higher SPC score, you are almost certain to eat BOTH less and less often. 

Near foolproof and far less effort required
