Here is the SP expert answer: www.sparkpeople.com/community/ask_the_expe
If you are eating at a calorie deficit, it is unlikely you will be building a significant amount of muscle mass, certainly not in just 5 weeks. Building muscle requires a calorie surplus. (That's why body builders eat more than their maintenance.) You can improve quality, but only to a point. There's no set amount of time that your water retention will last; if you continue to challenge yourself, it may hold on!
Realistically though, it won't stop you from losing weight (nor fat) but it's mostly just masking what's really happening.
IF you aren't losing weight, then it's time to look at your diet. What does "eating right" mean for you? Are you weighing, measuring, and accurately tracking the food you put in your body? What's your current calorie range, and how much are you actually eating day to day?
Your page is private, s o I can't see your trackers. SP does have a great series on how to break a plateau. Here's the first article: www.sparkpeople.com/resource/fitness_artic
