In plain English

If you're overweight and have Hashimoto’s thyroiditis, cutting back on carbs for three weeks might help you lose a little weight and lower your BMI, even if your thyroid hormones don’t change.

See the scientific wording

A 3-week low-carbohydrate diet in overweight adults with Hashimoto’s thyroiditis is associated with a 5% reduction in body weight and a 4% reduction in BMI, independent of changes in thyroid hormone levels, suggesting carbohydrate restriction may improve metabolic parameters without altering thyroid function.
