Kimkins & Low Thyroid
Here's a case where Heidi Diaz / Kimmer may know what she's talking about. In a recent blog post, she reviewed the symptoms of low thyroid. (She lifted a thyroid image from here and her words from somewhere else but failed cite her sources. Figures.)
What stood out for me was the fact that the Kimkins diet causes all those same symptom, and the Kimkins Survivor blog is filled with accounts from people whose thyroids went bad while on Kimkins. Every one of the symptoms Heidi Diaz mentioned in her post were symptoms heard often from people who followed her diet.
