Start with the basic routine and stop looking at yourself, the results will come just be patient.

Learn to count your calories. In it's simplest form body weight is determined by calories in vs calories out, the more you exercise the more you're 'allowed' to eat. To help me count I use MyFitnessPal, an app that makes it so much easier.
