About this trial
The goal of this clinical trial is to learn whether adding the NutriSteppe digital dietary intervention to routine medical care improves metabolic health in adults aged 21 to 65 years with type 2 diabetes mellitus, obesity, or overweight with related health conditions. Participants are already receiving or have been prescribed glucagon-like peptide-1 (GLP-1) receptor agonist therapy by their treating physicians outside the study.
The main question is:
Does the NutriSteppe digital dietary intervention improve glycated hemoglobin (HbA1c), a measure of average blood glucose, after 12 weeks compared with routine medical care alone?
The study will also assess changes in fasting blood glucose, body weight, body mass index, waist circumference, cholesterol, triglycerides, blood pressure, diet quality, quality of life, dietary adherence, and safety.
Researchers will randomly assign participants to one of two groups. The control group will continue routine medical care and receive general lifestyle advice. The intervention group will continue routine medical care and use the NutriSteppe application for 12 weeks to receive personalized dietary support.
Participants in both groups will:
* Attend study visits and complete the examinations, laboratory tests, and questionnaires specified in the study protocol. * Photograph everything they eat and drink. * Have their food photographs automatically analyzed using Tagam-AI, a system developed for this study. * Be able to view the results of the food photograph analysis.
The photography and automated analysis procedures will be the same in both groups. Only participants in the intervention group will receive personalized dietary recommendations generated from these data through the NutriSteppe application.

Treatments tested in this trial
NutriSteppe Digital Dietary Intervention
BehavioralThe NutriSteppe mobile application provides personalized meal planning, a food diary, nutritional analysis, dietary goals, educational modules, culturally adapted recipes, progress monitoring, reminders, and dietary recommendations intended to support metabolic health and food tolerance during GLP-1 receptor agonist therapy. Participants use the application for 12 weeks, complete the food diary at least 5 days per week, record body weight weekly, review dietary suggestions, and complete weekly educational modules.

Trial outcomes
Primary outcomes
Change From Baseline in Glycated Hemoglobin (HbA1c) at Week 12
HbA1c will be measured as a percentage at baseline and at week 12. Change will be calculated as the week 12 value minus the baseline value. A negative change indicates a reduction in HbA1c.
Secondary outcomes
Change From Baseline in Fasting Plasma Glucose at Week 12
Fasting plasma glucose will be measured in mmol/L at baseline and at week 12. Change will be calculated as the week 12 value minus the baseline value. A negative change indicates a reduction in fasting plasma glucose.
Proportion of Participants Achieving HbA1c Below 6.5% at Week 12
The proportion of participants with glycated hemoglobin (HbA1c) below 6.5% at week 12 will be calculated as the number of participants meeting this threshold divided by the number of participants assessed.
Change From Baseline in Body Weight at Week 12
Body weight will be measured in kilograms at baseline and at week 12. Change will be calculated as the week 12 value minus the baseline value. A negative change indicates weight loss.
Percentage Change From Baseline in Body Weight at Week 12
Percentage change in body weight will be calculated as the difference between body weight at week 12 and baseline body weight, divided by baseline body weight and multiplied by 100. A negative value indicates weight loss.
Other outcomes
Frequency of Self-Reported Dietary Adherence Difficulties
Participants in the intervention group will select one or more dietary adherence difficulties experienced during the previous week. Responses are not summed into a score. Each difficulty will be reported separately as the number and proportion of participants selecting that response. Therefore, this outcome has no minimum or maximum scale value.
