Hey Mum of one, I am starting the GI diet today.

I have been on it a few other times, with enormous success. I love how I can eat whenever I am hungry, as long as I make correct food decisions. This diet is really about being motivated, because you can bend the rules a lot, but if you remain goal oriented then you should be fine.
Some meal ideas- Breakfast- fiber one (do they have that in england? I am from new york) with fat free milk and a fruit; hot oatmeal, fat free milk, berries; egg whites with sauteed veggies and a fruit.
For lunch I like to have salads with some grilled chicken or fish. I don't remember all that well, as it's been a long time since I was on it properly, but I will post more ideas as I am on it longer...
good luck!
