Instead of asking:
“Did the scale go down today?”
Try asking:
“Did I practice the habits I want to become normal?”
Was there a satisfying starch at the center of your meals? Did you eat the foods you planned to eat most of the time? Did you move your body? Did you get back to your normal routine after an imperfect meal instead of turning it into an imperfect week?
Those are signals you can actually use.
