Primary outcomes

  1. Effectiveness of mHealth apps at changing bodyweight assessed by bodyweight measurements over 6 months

    Time frame: 3 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

  2. Self-efficacy in weight management assessed by Weight Management and Nutrition Knowledge questionnaire

  3. Long-term change in diabetes via fasting blood glucose

    Time frame: 3 months

    Compare and determine which intervention elicits the most change towards diabetes via fasting blood glucose

    Outcome measure will be fasting blood glucose

  4. Quality of Life after using mHealth apps assessed by World Health Organization Quality of Life BREF questionnaire

    Time frame: 3 months
