What constitutes “falling off the wagon” in this program? In other words, what triggers a need to restart my count at Day 1?

Going back to “Day 1” is a very personal decision. In Bright Line Eating, there is no one standard rule and no judgment from the community on how you decide to count your days. This is a program of honesty. If you honestly think you have broken your Bright Lines and want to start counting again at Day 1, we are here to support you.
