Ah OK, well therein lies your problem hon. I find SW great but I find it only works if I am always prepared and bring my own breakfast and lunch and snacks into work with me - otherwise I'd just cave as we hold a lot of meetings here so there are invariably catering platters coming in every day with cakes, cheeses, sausage rolls.....you get the picture!
In the morning I have two wholemeal slices of bread with LoLo cheese, a poached egg and a satsuma and apple. Then for lunch I have a MASSIVE bowl of homemade vegetable soup with some melon and an apple. Then I have a yogurt as an afternoon snack and if very hungry will nibble on some smoked ham. I then have a generous dinner when I get home. I've a lot more to lose than you but I lost 3.5lbs this week (go me!) and I can honestly say I've never been hungry. I find it's when I'm hungry I make bad choices so try and plan out the night before what you are going to eat the next day and you will notice a big difference xx
