The Study
The ketogenic diet alleviates autoimmune thyroiditis caused by Th17/Treg imbalance by inhibiting the HMGB1/NLRP3 signaling pathway
This study tested a special high-fat diet on mice with a thyroid problem, and the mice got better. But mice aren't people, so we can't say the diet will help humans with the same problem—it just shows it might be worth testing in people.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Scientists gave mice with an overactive immune attack on their thyroid a special high-fat, low-carb diet. The diet helped stop the immune system from attacking the thyroid and reduced swelling and damage.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — the changes were strong and consistent across multiple biological markers, suggesting the diet directly calmed the autoimmune response in the thyroid.
- 2Mice on the keto diet had lower levels of thyroid antibodies (TgAb/TPOAb), less immune cell invasion in the thyroid, reduced inflammatory proteins (TNF-α, IL-6, IL-1β), and improved antioxidant levels (SOD, T-AOC).

In mice with iodine-induced autoimmune thyroiditis, a ketogenic diet caused a measurable decrease in body weight compared to a standard diet, likely due to metabolic changes from reduced carbohydrate intake, but this weight loss does not confirm any direct impact on the autoimmune condition of the thyroid.
In mice with autoimmune thyroiditis caused by iodine, a ketogenic diet is linked to less damage to thyroid tissue and better preservation of its structural organization.
In mice with autoimmune thyroiditis triggered by iodine, a ketogenic diet lowers levels of autoantibodies, reduces immune cell infiltration in the thyroid, and decreases concentrations of specific inflammatory signaling molecules.
In mice with iodine-triggered thyroid inflammation, a ketogenic diet lowers markers of inflammation (RORγt and IL-17) and raises markers of immune regulation (FoxP3 and IL-10), altering the immune environment in the thyroid.
In mice with iodine-triggered thyroid inflammation, a ketogenic diet lowers the activity of TLR2 and TLR4 proteins, which are involved in triggering inflammatory responses.
In mice with autoimmune thyroiditis induced by iodine, a ketogenic diet reduces activity in a specific inflammatory signaling pathway and lowers levels of three proteins involved in inflammation.
