Reddit mentions of The Hashimoto's 4-Week Plan: A Holistic Guide to Treating Hypothyroidism

Rediculous cover design but my naturopath gave me this when I was diagnosed:

Why Do I Still Have Thyroid Symptoms? when My Lab Tests Are Normal: a Revolutionary Breakthrough in Understanding Hashimoto's Disease and Hypothyroidism by Datis Kharrazian

It has great references towards self help, learning about your body, and really focusing on food and what you put in it then listening to how your body responds.

Speaking of food, there are cookbooks to help get over the humps of refocusing nutrition:

The Whole 30

• I lasted 25 days with a friend, felt my body positively respond after day 5
  
  Hashimotos 4-week plan
  
• this isn’t the simplest, I just took small elements of it as guidance since I’m not ready to fully commit to the 4 week full plan
  
  Hope this helps, thanks for asking the question.
