  • I finally convinced a dr to give me Armour thyroid. I have taken a synthetic thyroid since 1975. Now I no longer have heart palpitations and I can tolerate caffeine better. I have also started kemp drops for a healthy thyroid. I have not lost weight but hope this is in my future. I do feel better but started walking an hour a day so this most likely is one reason I am feeling better.

  • I’ve had several thyroid test, they came back negative. I have been to 4 drs. two of them are specialist in the thyroid. I have many of the syms. of thyroid. I don’t know what to do anymore.
    I read your order on ways to improve your thyroid.

  • Hi Dr. Hyman. I have been wheat free, gluten free and sugar free since May and I feel great. I have lost about 25 lbs so far, and have about 50-75 more to lose. I have cut drastically on dairy products, and now use Stevia as an artificial sweetener (only in my coffee). I eat as you describe above. For whole grains, I eat brown rice and every once in a while I have gluten free oats. One thing that has ALWAYS confused me is the conundrum of the potato — its from the earth, its whole and in its original form. There’s nothing processed about it. But often its at the top of the list of grains to avoid. I know that it probably has something to do with how it impacts blood sugar, but its still hard for me to wrap my head around why its important to say “no” to potatoes… considering its a whole food! Your thoughts on the “potato debate” would be much appreciated!

    • Hi Anne,
      Potatoes are rich in potassium and a good source of vitamin C, making them a good choice as part of healthy diet. If you are closely managing your blood sugar, cooking a potato and then refrigerating it for 24 hours will increase the resistant starch content and lower the glycemic index.
      Wishing you the best of health,

  • Hi Dr, Hyman

    One year ago, i was diagnosed with hypothyroid, Dr. did all tests, TSH, T3, T4 and antibodies and only TSH value was very high above 5.5. I am taking eltroxine (100 MCG) ever day, ir almost 6 months my fatigue was gone but my weight is not reducing , although i am trying hard to loose weight because i gained a lot during pregnancy and it did not go off after delivery.

    I have started to have body fatigue, mood swing , sever headaches, in the morning and also almost continuous shivering , these symptoms are getting worse. Can i have some guidence in this regard, if there is any test that i should do, what foods should i eat ?
