Design of the Why Wait WeChat Platform for Weight Reduction Management
weight loss
The online group was managed for weight loss through the Why Wait WeChat Platform, which includes two sections and nine modules. The two sections were the informative section (video teaching, compulsory course, Monday article and original submissions) and the functional section (diet form, resistance exercise, aerobic exercise, body measurement and homework feedback). The videos presented weight‐loss lessons, sports courses, action essentials, matters needing attention and practice time and frequency. The compulsory course presented knowledge about weight loss. A recent article about weight loss was uploaded every Monday. The participants had to take the courses at least once, but they could watch them, entirely or in parts, as many times as they wished. The video teaching and required reading took about 15 min for each course, and there were 56 courses in total. After learning, there was an assessment, and those who passed the assessment received points, and participants could redeem gifts according to the number of points.The video teaching used in this study was divided into two parts. One part was the correct training video from the coach, and the other part was the video to instruct the participants on the spot. For example, any possible misunderstandings and incorrect postures of the participants were corrected on the spot and uploaded by video.Original contributors shared their feelings during weight loss with others for encouragement. The participants in the same group could communicate with others online and on‐site, thus achieving the purpose of a virtuous circle.The participants were required to take photos and record their meals three times a day on diet forms each day. For resistance exercise, the participants were required to record the type of exercise, completion time, intensity and post‐exercise response. Aerobic exercises were recorded in the same manner. The total recording time was about 15 min. For body measurement, the participants were required to carry the Mi Smart Band bracelets daily, automatically recording daily steps, weight, body fat, muscle, protein, BMI, bone mass, water, BMR, skeletal muscle, visceral fat, sleep time and sleep quality. For operational feedback, the participants submitted homework and physical measurements daily, and weight loss managers replied within 12 h.
