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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Weight Management Intervention | Experimental | During a 12-month period, participants will attend a total of 22 diet improvement sessions, each of which will last approximately 1 hour. 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. Participants will be followed by daily self-weighing for 1 year after intervention. |
