Can a computer coach help rural americans lose weight?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * have a body mass index \[BMI\] \> 25-55 kg/m2; * home address in a zip code classified as non-urban; classification of an individual as living in a non-urban area will be determined by meeting any one of the following criteria: (1) having a home address corresponding to a Rural-Urban Commuting Area \[RUCA\] code of 4-10); (2) qualifying as rural under the Centers for Medicare and Medicaid Services Rural Health Clinic Program based on the 2010 or 2020 Census Bureau data; or (3) meeting the definition of rural from the Federal Office of Rural Health Policy; * have no physical limitations that prevent walking at a moderate pace for at least 10 minutes without stopping; * be able to provide informed consent; * have access to a smartphone and a computer or tablet with a video camera and stable access to the Internet (at home or work or some other stable source of access); * complete all screening and baseline questionnaires and activities. Exclusion Criteria: * only one member of a household may participate concurrently. * currently participating in another weight loss program, taking a weight loss medication, have a history of bariatric surgery, or lost ≥ 10 pounds during the past 6-months; * are pregnant, lactating, less than 6 months post-partum, or plan to become pregnant during the time frame of the investigation; * report a medical condition that would affect the safety and/or efficacy of a weight management program involving diet and physical activity (e.g., uncontrolled heart condition, dementia, bulimia nervosa or binge eating disorder, or other significant psychiatric problems); * or report conditions that in the judgment of the one of the Principal Investigators (MPIs) would render them unlikely to be able to independently follow the intervention protocol for 6 months, including conditions which might comprise their ability to engage independently with the intervention website materials, provide self-monitoring information on a smartphone app, attend Zoom video group or individual sessions at the available times (if randomized to receive these treatment components), and complete online questionnaires.
