This research is to expand a virtual weight loss and weight maintenance program to rural counties of Illinois. The program uses dietary and lifestyle modifications for adults with obesity. The EMPOWER weight loss program has proven to be effective in 3 previous trials. In this research, we target a rural participant population. Individuals in rural locations are more likely to be affected by obesity and have unique barriers to weight loss related to geographic isolation including access to health care, preventative care, grocery stores, social networks, internet, and cell service.
EMPOWER is a remote weight management program that uses an online textbook platform, E-Text, and mobile web application, MealPlot. This pilot study will test for feasibility of the EMPOWER program in a rural population prior to launching a full-scale study. Acceptability measurements will be collected at 3 months to evaluate for needed changes; Participants of the pilot study will be permitted to continue on with the full program.
EMPOWER is a 1-year intervention. Data is collected via 24-hour record and daily weighing using a Wi-Fi-enabled scale. 24-hour records and daily weights are collected within the program's proprietary MealPlot website. EMPOWER consists of 17 online sessions (45 minutes/each) and 12 individual advising sessions with a nutrition coach.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Weight Management Intervention | Experimental | During a 12-month period, participants will attend a total of 17 diet improvement sessions, each of which will last approximately 45-minutes. Twelve sessions will be held in the first 5 months and will be focused on safe and efficient weight loss. The participants will learn to create a personalized weight loss diet from their kitchen based on their diet practice and food preference. The next 10 sessions will be held in the last 7 months and will be focused on weight maintenance and healthy eating. The participants will build skills to select foods and create meals that prevent them from overeating. Flexibility in session completion will be allowed to accommodate busy schedules, vacation, and potential internet access challenges. |

All researchers must pass Core Human Subjects training through CITI. Confidentiality of data collected will be maintained by assigning each participant a three-digit identification (ID) code which will be used to enter all data in an electronic database. ID codes will be used on all documents and materials as the only form of identification; no names will be used. All files and participant documentation will be stored in locked filing cabinets. Electronic documents, forms and data will be stored in a Health Data folder on Box. Only the primary investigator, co-investigator, and research team will have access to stored data.
Any data collected via email will be completed using ID codes and deleted and emptied from trash following data collection. The primary investigator will immediately destroy documents that are obtained from individuals who do not qualify for the study, as determined during the pre-screening and screening steps. These documents will be shredded.
