Non Technical Summary
Obesity is one of the major health problems in the US. Simply put, a change in eating practice is required to solve the problem because chronic over consumption of energy is the primary cause of obesity. To achieve this, a practical way to obtain clear, quantitative nutrient information is required for evaluating eating practice and making changes with confidence. However, currently available nutrition facts labels are hard to use, and qualitative dietary guidelines are vague. Thus, there is a need to develop a new, effective approach.

Goals / Objectives
The proposal has the following three objectives: 1) Develop new nutrition graduate courses to train instructors who can lead a dietary weight management program, 2) Develop and test the efficacy of a dietary weight management program, and 3) Develop user-friendly, informative computer software that can enhance the efficacy of the weight management program.
Project Methods
Develop Nutrition Graduate CoursesTwo graduate courses will be developed to train instructors who can confidently lead a dietary weight management program. One course focuses on macronutrient metabolism to provide basis of weight management, and the other course covers micronutrients that are relevant to prevention of chronic diseases. More courses will be developed if necessary in the future.Develop A Dietary Weight Management Program And Test Its Efficacy The main goal of the program is to provide highly individualized advice based on cultural and personal preferences on diet. A personal food portfolio will be created using the FP2D by plotting foods that are frequently consumed by an individual. The portfolio will be used to learn how to combine food items to make a healthy meal, and also will be used to improve the individual's food environment. The nutrition knowledge acquired by an individual through this approach will provide a foundation for creating meals for both weight loss and weight maintenance.SubjectsWe will test the efficacy of the curriculum by conducting a controlled weight loss trial. Obese or overweight individuals (BMI>25) without major health concerns will be recruited for the trial (n = 50), and will be randomly divided into two groups: one for treatment and another for control (wait-listed).Dietary InterventionThe treatment group will receive intervention using the newly developed program, which is more flexible and personalized, relying on the knowledge development of participants to create their own weight loss diet. The treatment group will meet for 1 hour every week throughout the 20-week weight-loss trial. After 20 weeks of weight loss, participants will start maintaining their weight, and will meet every 2 months for follow up for one and one half years. The efficacy of the program will be evaluated by weight lost at the end of the weight loss trial, and the final weight after the 1.5-year follow-up.Outcome MeasurementsThe main outcome to be measured is the change of body weight. Weight will be self-monitored every day, and measured in class visits every 4 weeks during weight loss and every 2 months during maintenance. A second outcome is the change in diet, which will be assessed by a food frequency questionnaire at the baseline and at the end of the follow-up.Development Of FP Plot SoftwareA computer programmer will be hired for this task. A brief description of software specification is as follows: 1. Runs on Windows OS. 2. Uses the USDA food database. 3. Can plot multiple food items as color-coded circles on a fiber-protein chart based on the fiber and protein values per kcal basis. 4. Can calculate and plot a combined value of multiple foods for meal planning. The software will be based on the prototype, which will be modified to improve its usability.

Outputs
Target Audience:The second group of participants (n=30) to a weight management program were recruited from the campus community. They started the program in March of2019 and will complete a follow-up phase in March of 2021. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Anew course "Molecular Basis of Metabolic Syndrome and Weight Management" was first offered in 2016, and has been taught to approximatelytwentygraduate students every year. How have the results been disseminated to communities of interest?Disseminated at two scientific conferences, Obesity Week 2020 and Nutrition 2020. What do you plan to do during the next reporting period to accomplish the goals?We are converting the weight management program from in-person to an online format to increase accessibility. We will test the program with underserved, rural clients in collaboration with Extension educators in Illinois.

Impacts
What was accomplished under these goals? Objective 1: Anew course "Molecular Basis of Metabolic Syndrome and Weight Management" was first offered in 2016, and has been taught to approximatelytwenty graduate students every year. Objective 2: The second cohort is in the follow-up stage, and the third cohort will be enrolled to the program in 2021 Objective 3: Developing a mobile app, MealPlot, that will becompleted in 2021

Outputs
Target Audience:The second group of participants (n=30) to a weight management program were recruited from the campus community. They started the program in March, 2019 and have been continuing the program. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Two graduate courses titled Weight Management and Prevention of Cardiovascular Disease had 12 and 22 students enrolled, respectively in this reporting period. Four graduate and 10 undergraduate students weretrained through the weight management program in this reporting period. How have the results been disseminated to communities of interest?A poster was presented at the annual ASN conference. What do you plan to do during the next reporting period to accomplish the goals?We will develop amobile app (Objective Three)and convertthe program to being online to increase accessibility

Impacts
What was accomplished under these goals? Work is ongoing to refine the program described in the Objective Two.
