Your story is so inspiring, Chris. I am glad you shared it. Having such a disciplined approach and motivation is exceptional. Several friends in my social circles tried similar approach and addressed their insulin resistance problem and resolved diabetes.
In my opinion losing weight is not critical but reducing visceral fat it important to prevent metabolic syndrome and reduce risk for other deadly diseases such as cardiovascular and cancers.
I posted a new article within this context so adding it here as a reference.
Thank you for reading and sharing your experience. I wish you all the best in your health journey.
