Summary

This study tests whether a personalized low-calorie Mediterranean-style diet, combined with lifestyle coaching, can prevent people newly diagnosed with Graves' disease from regaining too much weight after their thyroid levels normalize. Fifty-four adults will be randomly assigned to either the diet program or standard care, and followed for a year. The goal is to see if the diet helps maintain a healthy weight and improves body composition.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Intensive Lifestyle Intervention (personalized low-energy Mediterranean-style diet and lifestyle counseling)
What this could lead to
If it works, this could show that structured dietary support helps people with Graves' disease avoid unhealthy weight gain while on standard medication.
What could go wrong
This is a small early-stage trial (54 people) testing a behavioral change, not a drug. Results may not apply to everyone, and sticking to the diet long-term can be challenging.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria * Diagnosis of Graves' disease in an endocrinology setting based on the presence of thyrotoxicosis and positive TRAb antibodies. * Diagnosis of Graves' disease within 1 month prior to randomization. * BMI \> 16 kg/m² and \< 35 kg/m² at the time of the first visit for Graves' disease. * Age \> 18 years. * Ability to commit to the duration of the study. * Ability to provide informed consent and willingness to participate in the study. Exclusion Criteria * Relapse of Graves' disease or thyrotoxicosis not related to Graves' disease. * Any serious cardiovascular or renal event in the last 6 months. * Current pregnancy, breastfeeding, or planning pregnancy during the study period. * Any condition potentially leading to fluid overload such as heart failure (NYHA class \> I) or liver cirrhosis. * Previously diagnosed significant psychiatric disorder (e.g., schizophrenia, post-traumatic stress disorder, obsessive-compulsive disorder). * Active eating disorder. * Uncontrolled depression. * Uncontrolled epilepsy. * Known cause of malabsorption (including uncontrolled celiac disease, lactose intolerance, or inflammatory bowel disease). * Ongoing therapy with weight-modifying medications (e.g., GLP-1 analogs, metformin). * Estimated BMI before disease onset \< 18 kg/m². This parameter will be calculated based on the "estimated pre-disease body weight" as reported by the patient.
