Thyroid problems
In the case of the thyroid gland’s existing diseases, such as hypothyroidism or Hashimoto’s thyroiditis, an autoimmune disease of the thyroid gland, we do not generally advise against the ketogenic diet.
But we advise you to take a consultation with the treating physician or alternative practitioner and monitor your thyroid hormones closely.
Also, make sure to get enough nutrients for the thyroid gland, such as iodine, selenium, vitamin B, omega-3 fatty acids, and iron.
