There can be a variety of reasons that you have seen a shift in weight. If you have added fitness to your routine, weight gain from holding on to water is the likely cause especially if you have not changed your eating routine. This Ask the Expert explains why this happens. www.sparkpeople.com/community/ask_the_expe
I took a look at your shared tracker information and it seems you also have fast food regularly which tends to be higher in sodium and that can add to your fluid retention issues as well. Now that you have the tracking down, perhaps you can take another step and begin making lower calorie choices when you are visiting fast food restaurants. Our Dining Out Guide can help you find options. www.sparkpeople.com/resource/sparkdining.a
Hope that helps. Don't get freaked out just keep taking small steps forward in your daily goals to help you move on.
