DiaMester e-health lifestyle program for adults with type 2 diabetes (pilot)

Official title: DiaMester: E-health Lifestyle Program for Improved Self-management and Remission of Type 2 Diabetes - a Pilot RCT

Run by Oslo University Hospital · NCT07361640 · Data updated 2026-11-12

This pilot will test whether an app-based coaching program, with or without a short low-calorie diet phase, helps adults with type 2 diabetes lose weight and improve self-management over 12 months.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with type 2 diabetes of 0–6 years' duration, BMI >27 kg/m2, specified HbA1c levels depending on treatment, a desire to lose weight, stable recent weight, and ownership of a smartphone are ideal candidates.

Probably not a fit

People using insulin, with recent major weight change or recent start of weight-loss drugs, very high HbA1c, severe kidney impairment (eGFR <30), or active cancer are excluded and may not benefit from this program.

What this trial studies

This is a three-armed, parallel-group randomized pilot comparing usual care to an e-health coaching program alone and the same program plus a low-calorie total diet replacement induction phase. Adults with recent-onset type 2 diabetes, BMI >27 kg/m2, and smartphone access will be randomized and followed for 12 months to measure weight change, self-management behaviors, and metabolic risk markers. The DiaMester app provides secure messaging with one of six trained health coaches (dietitians or diabetes nurses) who deliver tailored diet and activity support and monitor progress toward agreed weight targets. The pilot focuses on feasibility and whether the program achieves clinically meaningful weight loss and related metabolic improvements compared with usual care.

Why it matters

Potential benefit: If successful, the program could help people with early type 2 diabetes achieve substantial weight loss, improve glucose control, and potentially lead to diabetes remission through a scalable app-based coaching model.

How similar studies have gone: Previous trials using structured low-calorie total diet replacement (for example DiRECT) have produced substantial weight loss and diabetes remission in some patients, and digital coaching programs have shown promise though results vary.
