Here what your saying girls....I did LL last year and as soon as I started to eat "normally" I put on half a stone in a week, but that was expected. As you both know, your first week's weight loss is retained water and glycogen. As soon as you start eating "normally" again (say carbs etc) your glycogen stores re-fill, which can weigh between 5-7lbs in body weight.
I believe when you finish any strict diet such as LL, CD, Atkins, CS etc you will tend to put a few pounds on but it should stable itself out in a week or two with no further weight gain thereafter, providing your eating within your daily recommend calories etc. So I guess the aim is to get around 5lbs under target weight to allow for this natural weight gain when you finish the diet.
I really feel for you sharon Kim, I'd be gutted if I'd only ate a bowl of cereal and a slice of bread and put on 2lbs during that week - I can see where you're coming from. x
