Summary:

Sedentary adults, mostly overweight, completed a values-affirmation exercise and received a health message focused on the benefits of increasing activity and decreasing sedentary time once per day for a month. As compared to a control condition that received the same health messages but did not complete the affirmations, those in the treatment condition showed less sedentary behavior over the month, as assessed by wrist worn accelerometers. In addition, the initial affirmation, completed in an fMRI scanner, led to increased activity in the ventromedial prefontal cortext (VMPFC), a brain region associated with self-related processing and positive valuation.
