I found the white rice didn't work for me. But my dh eats it occasionally. I can eat a little yam (the less sweet ones) but it's better to do it at dinner.
When I first found the PHD I thought it was very close to what I was doing and followed it for a few months. I gained weight and didn't feel better.
I'm following Peat more now but as he says, people who want to lose weight should use the tropical fruits for glucose rather than the ice cream. I, of course, went with the ice cream and gained weight. Now, I'm using pears, cantaloupe, apples, peaches. But only a bit for the glucose.
I could say lots more but have to get busy. Great topic. Thanks.
