I buy mine from my local health food store. They keep them in the freezer section there. I was never big on tortillas so I can take them or leave them, but my DH LOVES them! I've made enchiladas with them a couple of times and they were yummy! Since I rarely eat them, I can't say whether they stall me or not, but they haven't seemed to slow the husband's weight loss down; he's lost 33 lbs since January.
