Be careful weighing everyday, that will not be an accurate representation of your weight loss and health. Weight fluctuates heavily, and you can never be sure what is the cause of a few ounces here and there and if it is a bad or good sign. You want the long term data every few weeks to see if it is working. I personally stopped weighing myself at all in between doctor visits, but most studies seem to put the optimal weigh in at around 2 weeks.
Also, when you are really getting started remember that muscle weighs more than fat, but in turn helps burn more fat. An uptick might not be because of something you did bad, but something you did good! It is impossible for you to tell if the extra pound you see one week is bad dieting or good exercise, particularly as muscle should build fairly quickly in the beginning. (Which is a common pitfall psychologically, as people think their efforts aren't working when they very much are.)
Muscle aside, you may still not see results from doing everything right. The body has to figure out how to find equilibrium with your changed habits, and may sometimes react by not dropping weight when mathematically it should be. The key is giving everything due time. Weight management is a marathon that lasts a life time, not a sprint.
