Dietary Approaches for the Management of Overweight and Obesity in Type 1 Diabetes

Dietary Approaches for the Management of Overweight and Obesity in Type 1 Diabetes: The D1ANA Study

Sponsor

Fundación Pública Andaluza para la Investigación de Málaga en Biomedicina y Salud

Enrollment

75 participants

Start Date

Jul 2, 2026

Study Type

INTERVENTIONAL

Conditions

Obesity, Overweight Type 1 Diabetes (T1D)

Summary

Although type 1 diabetes (T1D) has traditionally been considered a disease associated with a lean phenotype, it is estimated that up to 2 out of 3 people living with T1D are overweight or obese, factors linked to an increased risk of complications in these patients. The available evidence regarding nutritional strategies for weight loss in T1D is very limited, and clinical trials are needed to determine how to effectively and safely promote weight loss in this population. In recent years, low-carbohydrate diets and several intermittent fasting protocols have demonstrated efficacy in promoting weight loss both in patients with type 2 diabetes and in patients with obesity without diabetes. This study will evaluate the efficacy of moderate carbohydrate restriction, time-restricted eating, and standard calorie restriction for weight loss in adults with T1D and overweight/obesity.
