Technology is changing the opportunities to deliver behavioral weight loss programs and providing a way to extend their reach to wider audiences. Commercial programs that were once completely delivered via in person meetings at brick-and-mortar businesses are now expanding to virtual programs. WW (formerly known as Weight Watchers) is an industry leader and one of few commercial programs that has significant evidence for efficacy on weight loss. Their program currently includes a mobile app - that helps people follow the WW Program, rewards for consistent tracking and achieving milestones, an online community to connect with other users, and a 24/7 text chat with coaches.
Previous research by the investigators and others reveals that greater engagement in an online group-based weight loss program is associated with greater weight loss. We have found that an online group coaching program paired with a calorie tracking mobile app is effective at producing weight loss. WW is testing a new comprehensive program that involves an updated program paired with virtual workshops that offer actionable behavior change techniques for members, led by a trained WW coach. They have agreed to fund us to perform a one-arm trial of their new comprehensive program that includes a holistic approach to healthy lifestyle (activity, diet, and mindset). Findings will inform the continued development of this program. Our aims are as follows: 1) To examine the preliminary outcomes and acceptability of a multicomponent online commercial weight loss program that includes a mobile app, incentives for tracking, weekly virtual workshops, and an online community. Preliminary outcome is defined as weight change from baseline to 3 and 6-months. Secondary preliminary outcomes include changes in diet quality, physical activity, quality of life, sleep quality, and food cravings from baseline to 6 months. Acceptability of each program component and the overall program will be evaluated at 6 months. 2) To examine whether greater app use, greater engagement in the online community, and engagement with a higher number of peers (in the online community) predict greater weight loss at 3- and 6-months. 3) To examine the associations between total use of program components (and each individual program component) and change in weight. We hypothesize that greater use of program components (individually and total) will predict greater weight loss.

Experimental: Lifestyle Modification Program
This 6-month intervention includes the use of three components: WW's mobile app, virtual workshops, and a private online community. The WW Program involves: self-monitoring of weight, dietary intake, and physical activity; making dietary changes; increasing physical activity; shifting to a more helpful mindset; and learning behavioral strategies to manage these goals. Each week, participants will set goals and weigh-in with a coach via virtual workshop. Participants will be encouraged to use the app and private online community daily and attend weekly virtual workshops. The weekly virtual workshop led by a trained WW Coach features a behavior change technique and enables the participant to practice it to support their goals. These are actionable techniques and strategies that are grounded in scientific research.
Behavioral: myWW App, Virtual Workshops, and Private Facebook Group
The 6-month intervention includes the use of WW's mobile app, weekly virtual workshops, and a private online community. Participants are given a personalized food plan based on expert healthy eating guidelines and the latest nutritional science, an activity plan designed to promote regular physical activity and techniques to help shift members towards a helpful mindset for lasting change all within the WW app. Participants will attend weekly virtual workshops led by an expert WW Coach. The coach will help with goal setting, overcoming setbacks, and follow-up on progress toward goals each week. Participants will be encouraged to participate in a private Facebook group that gives participants an opportunity to receive motivational support from each other. Participants can post about their journey through photos, videos, and comments.
- Intervention Use [ Time Frame: 6 months ]Feasibility of the intervention will be assessed by measuring use of each app feature, engagement in the online community (via Grytics for Facebook), and attendance of virtual workshops.
- Intervention acceptability [ Time Frame: 6 months ]Participants will answer questions related to their experience with each program. Acceptability of the intervention will be assessed using a satisfaction survey at the end of the program asking about all intervention components and the overall program.
- Change in Weight [ Time Frame: Baseline to 3-months ]Weight will be measured using a smart scale at all assessments. Weight change will be measured from baseline to 3-months.
- Change in Weight [ Time Frame: Baseline to 6-months ]Weight will be measured using a smart scale at all assessments. Weight change will be measured from baseline to 6-months.
- Change in Diet [ Time Frame: Baseline to 6-months ]Changes in diet will be measured from baseline to 6-months using the 5 Factor Screener 2005 NHIS. This is a 19-item measure assessing approximate intakes of fruits and vegetables, fiber, added sugar, calcium, red meat, and cereal. The screener asks respondents to report how frequently they consume foods in 18 categories. No portion size questions are asked.
- Change in Physical Activity [ Time Frame: Baseline to 6-months ]Changes in physical activity will be measured from baseline to 6-months using the Global Physical Activity Questionnaire (GPAQ). The GPAQ has questions assessing activity at work, travel to and from places, and recreational activities. The number of minutes spent on each activity is assigned a METs value to determine level of energy expenditure. The higher the METs value the higher the activity level.
- Changes in Quality of Life [ Time Frame: Baseline to 6-months ]Changes in quality of life will be measured from baseline to 6-months using the Impact of Weight on Quality of Life-Lite. This is a 31-item measure assessing physical function (11 items), self-esteem (7 items), sexual life (4 items), public distress (5 items), and work (4 items). Scores range from 0-100, with 100 representing the best quality of life.
- Changes in Sleep Quality [ Time Frame: Baseline to 6-months ]Changes in sleep quality will be measured from baseline to 6-months using the Pittsburgh Sleep Quality Index. This measure contains 10 items to assess sleep quality with a score possible score of 0 - 21. Lower scores represent better the sleep quality (< 5 is associated with good sleep quality; > 5 is associated with poor sleep quality.
- Changes in Food Cravings [ Time Frame: Baseline to 6-months ]Changes in food cravings will be measured from baseline to 6-months using the Food Craving Inventory. This inventory includes 33 foods that are scored based on level of craving ranging in answers from 1 (Not at all) to 5 (Extremely) for each.
- Changes in Hunger [ Time Frame: Baseline to 6-months ]Changes in hunger will be measured from baseline to 6-months using the Hunger VAS (Visual Analogue Scale). This one-question measure asks "How hungry did you feel over the past week" and is composed of a line with words anchored at each end describing the extremes (Not at all hungry, Extremely hungry). Participants are asked to make a mark on the line corresponding to their feelings and quantification of the measurement is done by measuring the distance from the left end of the mark.
- Changes in Behavioral Automaticity [ Time Frame: Baseline to 6-months ]Changes in behavioral automaticity will be measured using the Self-Report Behavioral Automaticity Index (SRBAI). This 4-item measure assesses whether Behavior X is something... "I do automatically", "I do without having to consciously remember", "I do without thinking", and "I start doing before I realize I'm doing it". Items are scored using a 7-point Likert scale ranging from strongly disagree to strongly agree.
- Changes in Self-Compassion [ Time Frame: Baseline to 6-months ]Changes in self-compassion will be measured using the Self-Compassion Scale. This is a 26-item measure of self-compassion that consists of six subscales: self-kindness, self-judgement, common humanity, isolation, mindfulness, and over-identified. Subscales are computed by calculating the mean of subscale item responses. A total self-compassion score can be obtained by reverse scoring the negative subscale items (self-judgement, isolation, and over-identification) and computing a grand mean of all six subscale means.
- Change in Well-being [ Time Frame: Baseline to 6-months ]Changes in well-being will be measured using the WHO-5 Well Being Index
