I am on thyroid. We did a thyroid test at the end of the 7th week. It had gone from high normal to lowest normal. Something predicted by my doc. He told me that calorie restriction can cause the thyroid to decrease (metabolism to decrease). So, at the end of the 8 weeks, I’ll go to regular Mediterranean for 5 days and 2 days of 800 calories. That will start this Sunday.
I think diet is such an individual thing. It just so happens that if i followed as close as possible to what Dr. Mosley suggested, I did fine.
I’m not sure how the doc is going to handle the lowered thyroid. I see him next week. My guess is wait and see if the introduction of calories after a while corrects it. I understand that it takes about 2 months for a new thyroid test to be accurate. So, i’m going to guess we’ll wait for a second test and then decide whether to increase my dosage.
Hope this helps. Good luck, you sound like you’ve got a good start! Congratulations!
