Just wanted to mention that the stone didn't go just because I cut down on the bread (obviously), I walk as well (as I did the last time, when I cut it out completely).
Another tip, get smaller plates. Fill the smaller plate, makes you believe you're eating alot. Put the same amount on a larger plate and you think "good, god, I need more". Eat 6 times a day, if you're awake for 12 hours, eat every 2 hours, a balanced meal/snack each time. Keep in mind though that if you're up til 2 in the morning (it's not a good idea to have a meal at that late hour). Upto about 8pm, try not to eat after that.
For Chocaholics, I find Cadburys Highlights helps. It's what I have in the evening before bed, gives me my choc fix and only 40 cal per 3 tsps.
You're probably thinking "well if you know so much, how come you have 3 1/2 stone to lose". I made the mistake of not keeping up the walking and healthy eating after the last time. Fingers crossed, I will listen to my own advice this time.
