Low-carb diet to treat Type 2 diabetes in teens.

Carb Control: Low-Carbohydrate Dietary Intervention for Pediatric Patients With Type 2 Diabetes

Not applicable Interventional University of Alabama at Birmingham · NCT06902077

This 24-week test will see if a low-carb diet helps control blood sugar and improve insulin function in teens (ages 12–18) with Type 2 diabetes who are not using insulin.

What this trial studies

Adolescents with Type 2 diabetes will follow either a low-carbohydrate diet or a standard-carbohydrate diabetic diet for 24 weeks while researchers monitor blood sugar control and markers of insulin function. Participants must have had diabetes for more than three months, HbA1c between 6.5–8.5%, BMI above the 85th percentile, negative pancreatic autoantibodies, and be on a stable dose of permitted diabetic medications; current insulin users and those with significant kidney or liver dysfunction are excluded. The study compares changes in HbA1c, measures of insulin sensitivity, medication needs, and body composition between the two diet groups. Regular clinical visits and laboratory testing will track safety and metabolic outcomes over the trial period.

Who should consider this trial

Good fit: Teens aged 12–18 with Type 2 diabetes for more than three months, HbA1c 6.5–8.5%, BMI above the 85th percentile, negative pancreatic autoantibodies, and on a stable dose of non-insulin diabetic medications are ideal candidates.

Not a fit: Patients who are using insulin, have significant renal or liver impairment, or have diabetes outside the specified HbA1c range are unlikely to be eligible or to benefit from this protocol.

Why it matters

Potential benefit: If successful, a low-carb diet could improve blood sugar control and insulin function, potentially reducing medication needs and excess weight in teens with T2D.

How similar studies have performed: Low-carbohydrate diets have shown benefits for glycemic control and weight in adults, but pediatric data are limited to a few small studies and remain preliminary.
