I do find with myself though I am more satisfied not having the white carbs in my diet. Take a 1/4 chicken and chips for example. If I eat just the chicken I feel more satisfied hunger wise than when I eat the chips as well. I feel stuffed, but still hungry and am looking for more food sooner, even though I have eaten more calories than the 1/4 chicken on its own.
Chips have a high GI factor which means they cause a large and very quick increase in your blood glucose levels which releases large amounts of insulin into your body to regulate your those levels. This happens quite quickly so your left feeling hungry again really soon.

I'd be interested to know the GI of Nutragrain. Even though it's advertised as "ironman" food, I have a bowl and i'm hungry again about an hour later...off to check the net
