Fortin A, et al. - In patients with both type 1 diabetes (T1D) and metabolic syndrome (MS), researchers assessed how waist circumference, anthropometric and metabolic outcomes can be altered with two 6-month nutritional interventions, based on a Mediterranean (MED) or a low-fat diet. Patients were randomly allocated to either the MED-diet or low-fat diet group, both including subjects (50.9 ± 10.3 years old) with a mean body mass index of 30.7 ± 3.3 kg/m² and a waist circumference of 105.5 ± 8.9 cm. At inclusion, 3 and 6-months, anthropometric (primary outcome: waist circumference), metabolic and nutritional assessments were carried out. Based on the findings, a 6-month non-restrictive dietary intervention could contribute to weight management in patients with T1D and MS, with no significant differences observed between interventions for anthropometric and metabolic parameters.
