thats is great for a 1st weigh in, you have only just over 2 stone to lose now, the end is in site. just stick to it as much as you can, do SS+ if you struggle, but it will come off and a lot quicker than doing WW or SW and you don't feel hungry.
5lbs off is 5lbs off! You can never predict your weekly losses on this diet but stick to it and you'll lose your stone a month, maybe even more. Congrats on the 5lbs and keep going!
Wow! That's a great loss! The most I've lost per week so far is 4.5lbs! Every little bit adds up, so don't be disappointed at all. You are doing really well.
