Brief summary
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.
Detailed description
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.
Interventions
BEHAVIORALWeight Management Intervention
Participants attend virtual dietary education sessions and over time create a diet plan that satisfies their individual needs. Participants aim to lose 1-2 pounds weekly until a BMI of 25 is reached. Participants are evaluated through daily self-weighing, dietary records, and anthropometric measures of waist and hip circumference, and body composition.
