Wey hey, my first week and i lost 6lb, had a few naughty moments but still lost. Not sure about this ketosis lark though, not had any metalic taste, cold hands or feet, how do you know? I'm not even sure what it actually means if im honest!! If im in it and i slip up and have one mouthful of food or one chip off the kids plate does that mean i will come straight out of it or what? If so how long does it take to get back there on average. HELP PLEASE
