I am interested in trying IF, but am hesitant because I have hypothyroidism (dx about 4 years ago). I have only started feeling better in the past few months after the addition of T3 and iodine to Synthroid. Has anyone with hypothyroid tried IF? How did you fare? Thanks for any insight.

I have had thyroid issues in the past, though mild, and my current state is normal T4 and TSH, with low T3. I've just learned that this could be caused by estrogen dominance (see http://thehealthyskeptic.org/5-thyroid-patterns-that-wont-show-up-on-standard-lab-tests). I have tried IF without any problems at all. (I did about two weeks of alternate day fasting, about 22-26 hours at a time.)
But my question to you (and I'm being genuine, not sarcastic) is why would you suspect that having hypothyroidism would cause a problem for IFing? Maybe because of a possible net lowering of calories?

I have hypothyroidism. I take Armour thyroid and also do IF when I feel like it, with no downsides. I have like a 10 hr window of time I eat (I can eat a LOT), and then don't eat much the rest of the day. So during the IF I'm actually not hungry/full in the beginning. It doesn't seem to affect my hypo. I also like eating coconut oil so that may be helping.
Honestly, I think it is completely natural to do IFs. In my past, I ate rather paleo without knowing it (although not high-quality stuff at the time), and was very fit and thin, although I wasn't really aware of my body/diet at all (didn't think about it much, and didn't know why everyone else was so chubby! lol). I just listened to what my body wanted and ate till satisfied. At school, I was never hungry enough for lunch and often only went to fit in--I just naturally fasted and felt great. When I became more aware, I followed conventional wisdom to try and keep my figure, got really depressed/skinny fat/fatigued over 4+ years, and also developed hypothyroidism. I ate very few calories, and still fasted sometimes thinking about how it seemed to work before (definitely the WRONG time to fast!), and would push it until I got very cold/light-headed. Very bad times.
Now that I'm back to eating clean and paleo, I'm still on my meds but IF when I feel like it, just like before. I never get cold/lightheaded during a fast. Also the feeling of hunger is quite different than when I went on the grains/CW diet.
So, I think you should just listen to your body, but of course stay up to date with blood tests too. I can usually feel when my numbers are off (insomnia = too much, cold more easily = too little, etc). I remember one post saying if you're hungry when you fast, you're not ready for IF, which applies to anyone.
