It sounds like you're gaining muscle! After 11 days of consistently working out, you probably gained a pound of muscle. Don't worry about what the scale says, just think about how your clothes fit and your energy level. That's so much more important than a number :)
I personally don't like clenses or fasts because I don't think they are long lasting. Sure, you drop a few pounds, but you have to feel miserable while doing it, and it comes right back. The best thing to do it to keep doing what you're doing-- eat lots of fruits and veggies and exercise. Again (and I need to tell this to myself, too!), that number on the scale doesn't mean nearly as much as the muscle tone and confidence that you gain.
