re: I can't imagine anything worse than the Paleo diet.

I was borderline diabetic in Jan 2017. Cut out carbs completely, except for a side dish of green vegetables once a day. Cut out all sodas. In three weeks time, dropped over 20 lbs, focus is better, vision is better, sleep is better, etc etc. Full of energy. No food cravings. It is boring as hell, but I've turned myself into "eat to live, not live to eat" mode and I may have saved my life by doing so. While not an ideal dining plan, if you are in poor health and addicted to sugar and carbs, it's the way to go.
