What this trial studies

This study investigates the effectiveness of a one-year time-restricted eating (TRE) intervention on glycaemic control, body weight, and cardiometabolic risk factors in individuals with type 2 diabetes who are overweight or obese. The approach aims to address the challenges of traditional dietary interventions by tailoring the program to individual needs and promoting sustainable lifestyle changes. Participants will follow a structured eating schedule to potentially improve their health outcomes and reduce reliance on diabetes medications.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with type 2 diabetes, a BMI of 25 kg/m² or higher, and a habitual eating window of at least 12 hours per day.

Not a fit: Patients who have had bariatric surgery, use fast-acting insulin, or have severe hypoglycaemia may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could lead to improved glycaemic control and weight management for patients with type 2 diabetes.

How similar studies have performed: Previous studies on intermittent fasting and lifestyle interventions have shown promise in improving metabolic health, suggesting potential success for this approach.
