What this trial studies

This clinical trial evaluates the effects of a strict vegetarian diet combined with regular physical exercise and probiotic supplementation on patients with type 2 diabetes mellitus. It is a randomized, double-blind, placebo-controlled study that aims to assess changes in metabolic, inflammatory, and epigenetic parameters. Participants will be monitored for improvements in glycemic control, insulin resistance, liver function, and overall quality of life through various assessments including blood tests and imaging techniques.

Who should consider this trial

Good fit: Ideal candidates are adults aged 45 to 70 with a recent diagnosis of type 2 diabetes and a BMI between 25 and 40.

Not a fit: Patients using insulin, anti-obesity medications, or those with severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve glycemic control and overall health in patients with type 2 diabetes.

How similar studies have performed: Previous studies have shown promising results with lifestyle interventions in managing type 2 diabetes, suggesting this approach may be effective.
