well done on your 2nd week loss - you did so well in your first week that it seems disapointing when you lose a pound in your 2nd week - but just think - 9lb's in 2 weeks - that is brillliant.
AND - I've said it before and I shall say it again 'blush' - if you look at your weight loss over a month and then over 2 months and 3 months - it all evens out - ROUGHLY to between 1 to 2 to 3lb's a week - so it doesn't matter what you lost last week or this week - over a 3 month period it'll all even itself out.
Good luck over the next few weeks - keep going - you can do it and will feel fantastic when you get to your target.
Best Wishes.
