Thanks Sayrra, sorry forgot to reply to your post. I guess I had just hoped for 1-2 lb per week, rather than 3lb in 4 weeks, which is less than a pound per week, but maybe I'm impatient! I have about 2 stone to lose (from a starting weight of 10 stone 10lb). Although I wasn't following a specific diet before Low Carbing, I always watch what I eat just to stay the same. If I don't think about it and just eat, I gain weight rapidly (as at Christmas this year when I put on about 8lb in about 10 days 
).
Thanks also BIWI for the advice. I should be able to drink a bit more water.
I will try to add more fat, although I'm putting butter/mayo/oil on nearly everything and eating lots of avocados. I will try also with the meat, although normally I would only eat meat at all once or maybe twice a week. I would naturally always choose fish/seafood or chicken over meat.
The burgers were butchers own, so probably not too processed, but tbh I was only eating them to try and up my meat fat content, so I don't mind not eating them. Can probably manage without the bacon if I try hard enough.
I might be able to cut down the number of cups of tea I have, but don't think I can drink it black. I'm pretty much addicted to tea though, and will need my first 3 cups in the morning before I can function, so will find it hard to eliminate the cream altogether.
I'll let you know how I get on!
