Official title: Long-term Impact of a Low-carbohydrate Versus Low-fat Breakfast on Blood Glucose Control in Type 2 Diabetes
Run by University of British Columbia · NCT06814171 · Data updated 2026-11-12
This study tests if eating a low-carb breakfast can help people with type 2 diabetes manage their blood sugar better compared to a regular low-fat breakfast.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 30-79 with physician-diagnosed type 2 diabetes who are on stable medication.
✕Probably not a fit
Patients using exogenous insulin, taking multiple glucose-lowering medications, or those with certain medical conditions may not benefit from this study.

What this trial studies
This clinical trial investigates the effects of a low-carbohydrate breakfast on blood glucose levels in individuals with type 2 diabetes. Participants will receive guidance to consume a low-carb high-fat breakfast for one year, compared to a standard low-fat breakfast control group. The study aims to assess improvements in glycemic control, variability, body weight, and feelings of hunger. The primary outcome will be measured through HbA1c levels, while secondary outcomes will include glucose monitoring metrics and body composition changes.
Why it matters
Potential benefit: If successful, this intervention could significantly improve glycemic control and overall health for patients with type 2 diabetes.
How similar studies have gone: Previous studies have shown positive outcomes with low-carbohydrate dietary interventions for diabetes management, suggesting this approach may be effective.
