Scott, I buy both the MET-Rx® and Power Bar® at Nutrition Depot, a chain of healthfood stores in South Florida and maybe elsewhere. Box of 12 MET-Rx $21&change, box of 12 Power Bar $10&change. I eat one MET-Rx bar most mornings because I need the protein and calories (I avoid meat but do have fish 2-3 times/week). In the afternoon I have three snacks - one Power Bar, one banana, one apple. Tips: drink at least 8oz. water with MET-Rx bar; clean apple by scrapping very sharp knift perpendicular to skin, you will see lots of white flaky stuff come off, might be protective wax under which may be all kinds of residue, then rinse. Fruit is the best snack but Power Bars are convenient.
