Diet Habit, Obesity, Overweight, Weight Loss
Conditions
Brief summary
This research is to develop a virtual weight loss and weight maintenance program through dietary modifications for adults with obesity. Although scientific studies have shown the feasibility of rapid and safe dietary weight loss and subsequent weight maintenance, no efficacious dietary weight management program is widely available, and thus bariatric surgery remains the most reliable approach for weight loss/management. Safe and effective dietary weight loss and subsequent weight maintenance require flexible, individualized advice by an experienced dietitian/nutritionist.
Detailed description
EMPOWER is a remote weight management program utilizing an online textbook platform, E-Text, and mobile web application. EMPOWER is a two-year program: 1-year intervention, 1-year follow up. Data is collected via FFQ (NIH DHQIII), daily weighing using a wifi-enabled scale, and 24-hour dietary records via the web application. EMPOWER consists of 19 online sessions (45 minutes/each) and 3 individual advising sessions with an RD. EMPOWER aims to improve health parameters related to obesity, such as hyperlipidemia and hypertension. Health parameters will be monitored primarily by the subject's personal physician. Any test results will be sent to the EMPOWER research team for analysis via REDCap. EMPOWER team consists of social workers in addition to nutrition experts. The social work team aims to monitor and improve lifestyle, stress management, and behavior.
Interventions
BEHAVIORALWeight Management Intervention
Participants attend group and individual dietary education sessions. Participants create a diet plan that satisfies their needs. Participants aim to lose 1 pound weekly until a BMI of 25 is reached.
