"Maybe they exercise a little bit more the next day (after seeing a weight increase) or they watch what they're eating more carefully," co-author Jamie Cooper said in a statement. "The subjects self-select how they're going to modify their behavior, which can be effective because we know that interventions are not one-size-fits-all."
She also said, “People are really sensitive to discrepancies or differences between their current selves and their standard or goal. When they see that discrepancy, it tends to lead to behavioral change. Daily self-weighing ends up doing that for people in a really clear way.”
The scientists believe the subjects may have also changed their behavioral patterns, because they knew their weight would be recorded daily. They said their study was a form of intervention, it was effective because of its simplicity and adaptability.
The team now hopes future investigations will assess self-weighing using scales that do not provide additional feedback.
