2.  Obesity Epidemic  Leads to: ◦ Cardiovascular Disease ◦ Type II Diabetes ◦ Respiratory Disease ◦ Joint Damage  Expensive ◦ Insurance won’t always cover Registered Dietitian (RD) ◦ Gym membership/trainer

3.  3 behaviors required to achieve and maintain weight loss. ◦ 1.) self-monitoring of diet, physical activity, and body weight ◦ 2.) reducing energy intake ◦ 3.) increasing energy expenditure. Coons M, Roehrig M, and Spring B. The potential of virtual reality technologies to improve adherence to weight loss behaviors.

4.  Compared 3 self monitoring techniques ◦ 1.) use of standard paper record ◦ 2.) use of a personal digital assistant (PDA) ◦ 3.) use of the same PDA as mode two plus a customized feedback program.  Used DietMatePro software program  Participants using PDAs had increased weight loss Burke et al. SMART trial: a randomized clinical trial of self-monitoring in behavioral weight management-design and baseline findings.

5.  Can the use of mobile device applications (MDA) created for weight loss provide results similar to those obtained by persons receiving nutrition and exercise education and classes?

6.  2 groups  1.) Traditional weight loss group ◦ Subjects attended nutrition education and exercise classes ◦ Used data from 2008 B3 Program ◦ 12 participants  2.) MDA group ◦ Advertised using flyers in hospital ◦ 9 participants ◦ Used Myfitnesspal application

7.  Must be a Blessing employee  Must have a BMI of greater than 21  Must be willing and able to attend nutrition education and exercise classes

8.  1.) Must be a Blessing employee  2.) Must own and be familiar with using a mobile device capable of downloading applications  3.) Must have a BMI of greater than 21  4.) Must be in general good health  5.) Must not have attended nutrition education classes within the past year.  6.) Must be willing to document food consumption and exercise daily.

9.  All subjects ◦ Weighed at the beginning and end of study ◦ Heights were taken at the beginning of the study  Traditional Group ◦ Attended 45 min cardi/yoga class Monday-Friday ◦ 30 min strength training class Monday and Thursday ◦ Group therapy Monday ◦ Nutrition education class Tuesday

10.  MDA Group ◦ Instructed to use Myfitnesspal application everyday to record food intake and exercise ◦ Instructed to set a 1lb/week weight loss goal ◦ Instructed to workout a minimum of 30 minutes 3 times per week

11.  States that there is no significant difference in the percent weight loss of the traditional group compared to the percent weight loss of the MDA group.

12. Subjects % Body Weight Loss in lbs

13.  Traditional Group ◦ % body weight loss =1.67 to 8.83% ◦ Mean % body weight loss = 5.30%  MDA Group ◦ % body weight loss = 0.2 to 6.0% ◦ Mean % body weight loss = 3.11%  Two-tailed P-value ◦ 0.023 ◦ Statistically significant ◦ Reject null hypothesis

14.  B3 group had an average of 41.3% more % body weight loss  Subjects in the MDA Group stated advantages: ◦ Convenient ◦ Provided constant visual and motivation ◦ Made tracking calories easier ◦ User friendly

15.  Using an MDA does not provide the same weight loss as exercise and nutrition classes  MDAs do lead to weight loss when used properly  MDAs maybe still be a good tool for individuals who can not afford nutrition and exercise classes  More research is need!
