Efficacy of mHealth Applications in Weight Management in a Population Affected by Overweight or Obesity

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the effectiveness of mobile health applications in improving health outcomes in patients with overweight and obesity. This study will involve a 6-month long commitment where participants will be expected to use an mHealth app daily, weigh themselves and check their fasting blood glucose levels every morning.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effectiveness of mHealth apps at changing bodyweight assessed by bodyweight measurements over 6 months | Determine if the mhealth app is an effective weight loss modality compared to standard weight loss program (control) Outcome measure will be body weight in kg | 3 months | 
| Self-efficacy in weight management assessed by Weight Management and Nutrition Knowledge questionnaire | Compare and determine which intervention promotes self-efficacy in weight management. Reporting will be on a scale of 0-100, with higher scores indicating higher self-efficacy | 3 months | 
| Long-term change in diabetes via fasting blood glucose | Compare and determine which intervention elicits the most change towards diabetes via fasting blood glucose Outcome measure will be fasting blood glucose | 3 months | 
| Quality of Life after using mHealth apps assessed by World Health Organization Quality of Life BREF questionnaire | Comparing the two arms to determine which leads to greater quality of life (QOL) Measures will be reported on a scale of 1-5 across four domains. Scores will be converted to a scale of 0-100 | 3 months |
