The goal of this clinical trial (randomized controlled trial) is to examine the effectiveness of a holistic lifestyle mHealth intervention in reducing the risk of type 2 diabetes mellitus.

The study focuses on young adults aged 20-35 years, recruited from public and private universities in Rawalpindi and Islamabad, who meet the defined inclusion criteria.

The main questions it aims to answer are:

Does a holistic lifestyle mHealth intervention significantly reduce the risk of type 2 diabetes ? Does the intervention improve overall health-related quality of life and lifestyle behaviors, including diet, physical activity, and stress management?

Researchers will compare participants receiving the holistic lifestyle mHealth intervention (based on "Eat Well, Move More, Stress Less") with a control group receiving standard care or basic health guidance to see if the intervention leads to greater reduction in diabetes risk and improved health outcomes.

Participants will:

Use a culturally tailored mHealth application designed for the Pakistani context Follow lifestyle recommendations focused on diet, physical activity, and stress management Engage with intervention content based on the three core pillars: Eat Well, Move More, Stress Less Participate in periodic assessments, including health measurements and questionnaires Provide feedback on their experience and adherence to the intervention
