I started GI last week as well, lost 3lbs when I weighed yesterday
It's quite easy to do but as with most diets you need to get a bit inventive so you don't get bored.
Basically 1/4 plate is meat (lean ham, chicken breast no skin, fish, pork loin), 1/4 is carb (40g basmati or brown rice, 2/3 baby new pots, 40g spagetti), and 1/2 is veg.
The basis is that you eat slow release food to keep you full (it's based on a diabetic diet).
I had a real problem with bingeing. I'm now finding it really easy to stick to as I'm re-training my body to register when I'm full, and that's most of the time with this food!
Sorry to hear about your situation Shadden. The web it is a great place to get support.
