Firstly, don't be disappointed if you don't lose as much in week 2, it's very common. I lost 7lb week 1, then only 1.5lb week 2. But it has kept coming off and I'm 22lb lighter after almost four months. It would have been more but I've had a few holidays/weekends away where I didn't pay any attention to my intake and gained some weight back.
Definitely eat at least five syns each day.
Keep your water or decaf hot drink intake up.
Make sure you are eating HEs, particularly B as the fibre will help. I didn't eat many of mine in week 2 and I notice I definitely lose more in the weeks I have them.
Start looking for new recipes to try, there are heaps of Facebook groups or the SW website. Keep your menu fresh and exciting.
Start incorporating some more exercise (body magic) into your week if you can. Park further away, walk instead of bus etc. For me, being lighter made being active easier which in turn gives you more energy to be active and the positive cycle continues!
Don't get lazy and stop tracking your food diary. Even if it's on your phone and you fill in your paper one later in the day. They get you to do it for a reason. For me, it stopped those little mouthfuls here and there if I knew I had to own up to it and write it down!
Good luck.
