Hi Karen, I am on the 1000 plan at the moment too, on my 2nd week now and it has taken a bit of getting used to. I've tried to plan my day in advance and stick to timings as much as possible, one thing i have found though is having the bars and cereal kicked off my hunger immensely!! so i've decided to choose the lower carbs if possible, here's my typical day -
10am - CD porridge
12ish - poached egg, on toast with salad
2ish - ½ shake
4ish - ½ shake
6/7pm - a meal made from one the recipes in the book (tonights will be turkey kebabs with rice)
9pm - fruit
In between i have lots of coffee with milk and 2-3 litres of water, maybe a coke zero and a cup of boullion if I need it.
I lost 1lb this week but am definitely losing as my home scales have moved down even more this morning.
Not saying that i haven't felt hungry sometimes but i did notice it was definitely worse on the days i started my day with cereal or if I had pasta or CD bars.
Hope this helps, good luck for this week!
