The Study
Effects of low-carbohydrate diet therapy in overweight subjects with autoimmune thyroiditis: possible synergism with ChREBP
This study watched two groups of people for 3 weeks—one ate fewer carbs and the other didn’t—and noticed that the low-carb group lost weight and had fewer antibodies. But we don’t know if the diet caused those changes, because people chose which group to join. It’s like noticing kids who eat more candy are more hyper—but that doesn’t mean candy makes them hyper.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
People with Hashimoto’s thyroiditis who cut out bread, fruit, and sugar for 3 weeks saw their immune system attack their thyroid less, lost weight, and had trouble digesting milk.

Quality score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — fewer antibodies may mean less thyroid damage, and weight loss happened without changing thyroid meds.
- 2Antibodies dropped by 40–57%, weight dropped 5%, BMI dropped 4%, and 83% had lactose intolerance.

People who are overweight and have Hashimoto’s thyroiditis might lose more body fat if they eat more protein, fewer carbs, and avoid certain vegetables like broccoli and cabbage — even if they’re not eating fewer calories overall.
For overweight people with Hashimoto’s thyroiditis, cutting out carbs for three weeks might lower harmful antibodies in the blood, help them lose a little weight, and reduce their BMI — as if the diet is calming down their immune system and helping their body burn fat.
For people who are overweight and have Hashimoto’s thyroiditis, cutting back on carbs for three weeks might lower certain antibodies linked to thyroid inflammation — like a sign that the diet could be calming down the immune system’s attack on the thyroid.
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.
In people who are overweight and have Hashimoto’s thyroiditis, many of those with high levels of immune antibodies also can’t digest milk sugar well — this might mean that trouble digesting carbs is connected to how the immune system attacks the thyroid, possibly through a specific biological pathway called ChREBP.
Cutting back on carbs and cutting out sugary foods may help people with autoimmune thyroid disease feel better by stabilizing their metabolism and lowering body-wide inflammation.
