I'm trying to figure out how to get rid of obesity forever. I made a few illustrations to help me visualize the GKI/Boz ratio stuff.
I remember that I used to say (back in 2010 - when I had lost all the weight and was in the best shape of my life) that obesity would be easy to solve when any person could easily check their insulin level with a cheap at home test.
Well... that test still doesn't exist. But glucose & ketones together get pretty close to a proxy for a direct insulin test.
P.S. There are so many problems with thinking of these insulin numbers as "accurate" - they aren't - people vary way too much. But the spectrum is correct, and lowering your DBR or GKI is therapeutic.
