Great channel of podcasts.
Hi Jay. Could you please link to the episodes you mentioned at https://youtu.be/TKENTJQ0oT4?t=3827 ?
Such an informative episode. I was diagnosed in 2005 with Graves Disease. But in the last two years it has gone hypo due to the stress of my sisters death and then my husband with stage 4 cancer. I am working with a Naturopath, and I have been on Armour since April. However I am still having the same symptoms. (Except my sleep is better) She has not tested my rT3 and I think maybe she should. I have been wondering if maybe the thyroid is too much right now being I was also on low carb/carnivore/keto diet along with IF, but had stopped it a couple of years ago. I still struggle to stop the IF though. I had also under eaten and yo-yo dieted for decades. I wish I had this information when I was in my 20's.
Can I request a topic for a future video?
Bioenergetic fat loss case studies based on your respective coaching practices would be so awesome to see.
I know Jay has one testimonial on his website, where a guy lost significant weight.
I still can't figure out what that looks like in practice, in terms of lifestyle changes, if one is to pull it off without a caloric deficit, but rather by moving more and eating more.
Unless we are talking military bootcamp, rucking and eating tons of fibrous foods, I don't see how it can add up.
Thanks Jay for such an important podcast.
Most underrated channel on YouTube. How do you guys not have hundreds of thousands subscribers by now!
Awesome stuff Jay and Mike.
My TSH was slowly rising from the ages of 17 to 21 until it was about 2.5, and that was about the worst I ever felt. After finding Rays work at 24 I improved quite a lot for a couple of years along with your help as well. I then started taking thyroid for a few months and got my waking temps up to about 36.4 Celsius. My TSH went up to about 3.4! And that was the best I had felt in years. I strongly suspect (although I have no blood work) that it would have been suppressed in the meantime.
Great episode!
What is the optimal TSH level
Love that you guys are fixing people's issues with a Ray Peat inspired philosophy. So many think they can eat copious amounts of sugar and ice cream and then complain that "Ray Peat diet" doesn't work. U guys are proving that, properly understood, it does.
really appreciate the info. Low T3 has been a problem I've been trying to figure out for years now, got a more nuanced understanding of thyroid hormones and their mechanisms here than anywhere else I've yet to see.
