Good luck Kayjay! It was my first day today.
First thing was the hardest bit, stepping on the scales... 27st . Feel so embarrassed just typing that, but can't hide away from it any longer. Got to face this head on, and deal with it. So here goes.
I have done well with slimfast in the past, and would totally agree with Vicky, that is you can distract yourself during the day, then the hours go by and you don't miss food too much. Also agree that keeping topped up with water is really important.
Portion size is a really the main problem with me too, but that's why I like slim fast, because you have closely defined 'meals' bars or shakes. I'm not going to be too strict with my evening meal to start with, as if I can keep to a shake for breakfast and a bar for lunch, with a couple of slimfast snacks in the day I figure I'm doing pretty well.
today I started with a chocolate shake (I prefer the pre-made shakes in the bottles), was starving on my journey into work, but soon got distracted and totally bogged down, so was fine until a banana at lunchtime, my meal bar around 3pm then an apple on the bus ride home.
