Jodie, I'm so glad you posted your name because I would have a hard time referring to you as totalreject. It's much easier to lose weight if you have a better self image.
I have never heard of LighterLife. I googled it and it appears it is something that is only in UK. If it is a healthy diet and you are able to lose weight with it, go for it! Different things work for different people.
You can jump on in any discussion you see that interests you and find support from other 3FatChicks members who have the same goal. Also, there is a separate section just for UK members.

Good luck to you!
