I made the Strawberry Lime Avacado Prebiotic Shake from page 287 in the new Wheat Belly book.  My glucose reading pre-shake was 92.  When I tested at 40 minutes after beginning to drink it, my glucose reading was 107.  I made it completely following the recipe, green banana was "green" and size was half of a medium banana.  

Any thoughts .... I was hoping for less change than that.

I’ve been on WB since 2014 with tremendous success but working to get rid of my last few pounds and adding new protocols like LR yogurt etc.

Thanks very much!
