You'll get a lot of support and inspiration here. The folks are great here.
The best thing I learned here was how important correct refeeding is. In the past when I fasted I always just put the weight back on. I was very fortunate to hear what Chrisb1 and Monty said about re-feeding because now by re-feeding correctly I don't put it back on. I'm trying to heal myself without medication of a thyroid problem. Re-feeding correctly is very important.
