Mayflowers, pretty much any diet can work, up to a point, if you follow it to a tee. I even lost weight on a typical SAD type diet. It was just that it was 5 lbs in 3 years.

The issue with diets that claim to be low glycemic is that they may or may not be, first of all. And, second, of course, is that, as you identified, they really suck if you are IR.

Have you tried going Atkins induction for an extended time, with zero cheats? It's all that works for some people. I'm not quite there. But I do stay below 20 total grams carbs on a day to day basis, and once in a month or two, I'll go up to 30.

At 65, I'm finally creeping up (creeping down?) on 150, a weight I haven't seen since my mid 40's.
