Women with Hashimoto's thyroiditis who followed a gluten-free, Mediterranean, or combined diet for 12 weeks lost measurable amounts of weight and body fat around the waist and hips, even though they were not told to eat fewer calories.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether dietary patterns like gluten-free or Mediterranean diets consistently reduce body weight and adiposity in Hashimoto's thyroiditis across diverse populations and settings.
A systematic review and meta-analysis of at least 15 RCTs with 50+ participants each, comparing gluten-free, Mediterranean, or combined diets to control diets in adults with Hashimoto's thyroiditis, measuring weight, BMI, waist, and hip circumference at 3, 6, and 12 months.
Whether these diets cause weight loss independent of caloric intake in Hashimoto's thyroiditis, when energy intake is objectively measured and controlled.
A double-blind RCT with 120 women aged 18–65 with Hashimoto's thyroiditis, randomized to one of three diets (gluten-free, Mediterranean, combined) or control, with all meals provided and energy intake matched across groups for 12 weeks, measuring weight, body fat via DXA, and waist/hip circumference.
Whether adherence to these diets predicts sustained weight loss and reduced central adiposity over 2–5 years in Hashimoto's thyroiditis.
A prospective cohort study following 400 women with Hashimoto's thyroiditis for 5 years, assessing dietary patterns quarterly via validated FFQs and measuring weight, waist, and hip circumference annually, adjusting for medication, physical activity, and metabolic health.
Whether women with Hashimoto's thyroiditis who maintain weight loss for 1 year are more likely to have followed a Mediterranean or gluten-free diet compared to those who gained weight.
A case-control study comparing 100 women with Hashimoto's thyroiditis who lost ≥5% body weight over 1 year to 100 who gained ≥3%, matched for age and baseline BMI, assessing dietary patterns retrospectively via detailed food records.
Whether current adherence to these diets correlates with lower BMI and waist circumference in women with Hashimoto's thyroiditis at a single time point.
A cross-sectional survey of 800 women with Hashimoto's thyroiditis measuring current BMI, waist, and hip circumference alongside a single dietary assessment via FFQ to estimate adherence to gluten-free or Mediterranean patterns.
