Sue, what did you use your Hex B's on and what days do you typically do?
28g cereal, 4 ryvita, 2 slices wholemeal(400g loaf) 57g roll
red: 71g garden peas, 35g wholegrain pasta, 198g new pot/parsnip or 227g baking pot.
hope that helps a bit, the food diaries might be able to help you out a bit more!.
