I do believe that many people fall into an under eating trap like I did. Glad I could help. I think there is also a fear that if we are tracking and measuring macros and (gasp!) calories, that it is no longer intuitive and therefore not Primal. Even Mark recommends trying to hit certain levels of Protein and Carbs. I see nothing wrong with finding out exactly what our bodies need and making sure we hit those goals. BTW after a while, it does become intuitive again-tracking is not forever.
