Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This session one week later will last approximately 30 minutes. The investigator will confirm through ASA24 that the participant successfully completed three 24-hour recalls. To confirm that the participant successfully wore the Armband for at least 10 hours on the days the 24-hour recalls were completed, the investigator will download the Armband data using SenseWear software. After it has been confirmed that the participant completed these diet and physical activity measures, the participant will be randomized to the daily weighing group, weekly weighing group, or no weighing control group based on weight status. Participants in all groups will be provided with a handout containing general nutrition information about how to build a healthy eating pattern based on the 2015-2020 Dietary Guidelines for Americans.
Daily Weighing- Participants in the daily weighing group will be given a Yunmai SE Weight Scale and instructions for its use. Next, participants will be given instructions to download the Yunmai mobile app and create a user profile. Participants will be instructed to weigh themselves using the Yunmai SE Scale and app one time each day upon rising from bed (and before noon) after urination and in light clothing beginning in one week, every day for four weeks. Participants will be instructed to only weigh themselves using the scale provided during the duration of the study and to not allow others in their household use the scale. A reminder text and email will be sent to the participant to remind them to begin weighing on the assigned day. If on any day the participant has not weighed by 11am, the participant will receive an email and text reminder. After 2 weights have been collected, participants will begin to receive daily feedback on their change in weight and suggestions to maintain energy balance. They will receive an email between 12-1pm with this feedback stating, "Your weight today is \_\_\_\_\_\_\_. Your weight has (increased/decreased) \_\_\_\_\_ pounds since yesterday." If their weight has increased, the email will also contain a message stating, "If your goal is to maintain your weight, you may consider decreasing your energy balance by 150 calories" and will include one example of how to decrease their energy balance by 150 calories. If participants' weight has decreased, the participants will receive a message in addition to their feedback on change in weight stating, "If your goal is to maintain your weight, you may consider increasing your energy balance by 150 calories" and will include one example of how to increase energy balance by 150 calories.
Weekly Weighing- Participants in the weekly weighing intervention group will be given a Yunmai SE Weight Scale and instructions for its use. Next, participants will be given instructions to download the Yunmai mobile app and create a user profile. Participants will be instructed to weigh themselves using the Yunmai SE Scale and app one time each week upon rising from bed (and before noon) after urination in light clothing beginning the following day for four weeks. Participants will be instructed to only weigh themselves using the scale provided during the duration of the study and to not allow others in their household use the scale. If the participant has not weighed by 11am, the participant will receive an email and text reminder. After two weights have been collected, participants will begin to receive weekly feedback on their week and suggestions to maintain energy balance. Feedback and suggestions will be given as previously described above.
No Weighing Control- Participants in the non-weighing control group will be asked to refrain from weighing themselves for the next four weeks.
At the conclusion of the session, participants will be scheduled to return to HEAL lab three weeks later. This session three weeks later will last approximately 5 minutes. Participants will receive the Armband and be instructed to wear the Armband for a minimum of 10 hours each day during for the next week and reminded on how to complete 24-hour recalls using ASA24. Throughout the next week, participants will be randomly emailed on three days to complete three 24-hour recalls (1 weekend day, 2 weekdays). At the end of session, the participants will be scheduled to return to HEAL lab one week later. This session one week later will last approximately 60 minutes. Participants will be weighed and measured and be asked to complete follow-up questionnaires for eating attitudes, binge eating, unhealthy weight control behaviors, mood, and self-esteem. Participants will also be asked questions regarding their thoughts and feelings about self-regulation. Participants will also return the Armband and Yunmai SE Scale (intervention groups only) to the researcher. Handouts generated from ASA24 and SenseWear software that summarize the participant's dietary intake data from ASA24 and physical activity data from the Armband will be provided to the participants.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Daily Weighing
Participants will weigh themselves daily and receive feedback daily.
Daily weighing with daily feedback on weight
Participants will weigh themselves using a Yunmai SE Scale one time each day upon rising from bed beginning in one week, every day for four weeks. After 2 weights have been collected, participants will begin to receive daily feedback on their change in weight and suggestions to maintain energy balance. They will receive an email stating, "Your weight today is \_\_\_\_\_\_\_. Your weight has (increased/decreased) \_\_\_\_\_ pounds since yesterday." If their weight has increased, the email will include one example of how to decrease their energy balance by 150 calories. If participants' weight has decreased, the email will include one example of how to increase energy balance by 150 calories.
Weekly Weighing
Participants will weigh themselves weekly and receive feedback weekly.
Weekly weighing with weekly feedback on weight
Participants will weigh themselves using a Yunmai SE Scale one time each week upon rising from bed beginning the following day for four weeks. After 2 weights have been collected, participants will begin to receive weekly feedback on their change in weight and suggestions to maintain energy balance. They will receive an email stating, "Your weight today is \_\_\_\_\_\_\_. Your weight has (increased/decreased) \_\_\_\_\_ pounds since last week." If their weight has increased, the email will include one example of how to decrease their energy balance by 150 calories. If participants' weight has decreased, the email will include one example of how to increase energy balance by 150 calories.
No Weighing
Participants will refrain from weighing themselves.
