Go to your supermarket and have a look at the pre-packed Weight Watchers meals. Write down the ingredients and make yourself at home. I think there's one that consists of chicken, pasta, broccoli and a cheese sauce. You can work out the points for yourself. If you make a big enough portion, you can eat a quarter and freeze the rest. For example, 4 x chicken breasts = 6 points, pasta (for the amount I use) = 8 points, broccoli = 0, cheese sauce (low fat packet mix) = 10 points (I haven't made it for ages but it will be higher than the others). Total = 24 points but if you only eat a quarter, it'll be 6 points!
For a kick start, cut out bread, potatoes and pasta for a whole week. It's not that difficult for just one week. Eat cereal for breakfast, fish salad for lunch and maybe a chicken and rice dish for your evening meal. If you get really hungry of an evening (like I do) have a bowl of cereal. Shreddies are good because they fill you up until lunch time.
