Hiya and welcome maureen. I am also a part time worker, I work 21 hours a week. When first hearing about LL I wa put off by the price, but when I sat down and thought about it I realised how many times I had said "I'd give anything to be slim" nd I asked myself "so will I give £66 a week?" I knew it would be tight and I would have to sacrifice one or two luxuries but I knew it would only be for a short time and the difference it would make to my life wpould be phenominal. Turns out, 4 months in and 5 stone lighter. I really am no worse off than I was before. I could easily spend £70 a week pre LL on meals, sweets, junk food...... so I am if anything SAVING money. Not to mention I am happier, more confident, more outgoing, I have a grasp on the reasons why I overate in the first place. I used to think I just liked food...I was wrong.
There are so many reasons why we end up the way we are needing to lose weight. LL teaches you those reasons through behavioral therapy in agroup environment. I really do look at food differently now and know I will never need to do another diet again. I cant stress enough how valuable I found the councilling that lighter life provides, and I am looking forward to the route to management section, where LL gradually introduces food back to your life and teaches you how to make the right choices.
However, I have heard from lots of cambridge diet members who have lost equally large amounts of weight as us LLers. From what I gather it's very similar to LL, I think it may have a slightly larger variety of food replacement packs than lighter life. The meetings on CD are one on one I think, and you dont get the councilling that LL provides, I think it costs about £38 a week for CD.
Hope this helps, good luck with whichever diet you choose and keep in touch on here! x
