Daily self-weighing
For 20 weeks, participants in the intervention group weighed themselves twice daily (after waking up in the morning and before going to bed at night) using standardized digital scales. All participants were advised to wear nothing but undergarments to prevent the attachment of clothing weight to a BW measurement. In addition, a calendar for recording BW was given to illustrate the trend in the BW of individuals and raise awareness. After self-weighing, participants would record their BW on the calendar.
