Mfo - i don't argue that these bars cause stalls in some people, but just because you didn't lose weight from one day to the next, doesn't necessarily mean that it was the bars. Technically i think that a stall is not losing weight for 4 weeks or more... just so you don't unneccesarily cut out a lot of foods from your diet, because you aren't losing a specific amount of weight every day... good luck!! (i think most of those bars taste like sawdust anyways )
