Never had a slimfast shake then? they're vile!
Seriously, I used it years ago, and as a way of dieting it leves a lot to be desired. Maybe one or two as part of a diet, but all the time will drive you nuts.
I am currently on a sort of diet at the moment. I've cut out sweets, chocy and beer. I eat fruit for breakfast, I eat at regular times, and I eat things low in fat (no ready meals, low fat spread). For snacks I eat peanuts fromthe shell, and maybe ryvita. Salads are boring, but just vary what you have with them - chicken, ham, tuna, prawns etc.
Anyway, I'm losing it - had to punch an extra hole in my belt monday, and gotta do it again at the weekend.
My only problem is I'm losing it too much on the waist, and slowly on the tum.
Oh, and I do walk a lot because of my job, which must help.
