Since one of you (or both?) mentioned insulin resistance, I thought I’d chime in.
I’ve followed the Atkins diet for years with great results, but as an engineer, was swayed a little because there didn’t seem to be science backing up his results. I.e. he showed great studies, but not why the body reacted the way it did. Maybe I didn’t read the book closely enough.
I found Dr. Eades’ books Protein Power & Protein Power Lifestyle and their explanation of the science in the body was like a light bulb going off in my head. It all clicked for me.
One of the biggest points they discuss is Insulin Resistance and all the ailments that it brings on. These symptoms are usually diagnosed as something else, and the symptoms are treated, but not the root cause.
If you haven’t read them, and are interested in the science, I highly recommend these books.
