I could try to type out all of the things I talked about in the podcast, but I think it would be better to just post some really great videos and resources where I started learning all of this information from. These guys explain these concepts so much better than I do. The videos below from different doctors started me on a journey that ended up drastically changing the way I live my life every single day - and allowed me to help people in their weight loss journey as well. Just a fair warning... these videos will lead you to the entrance of the diet rabbit hole. However, I can promise the end of the rabbit hole contains some extremely satisfying information.
