Shootingstar nails it. Don't get overly stressed about miles and miles of riding. Just ride your bike as much as you can, hopefully everyday. If you can't ride, then walk, everyday. It is a journey not an instant result. I like to use myfitnesspal.com for tracking my food. At the moment I am doing a higher protein, less carb and strength training but when I ride I balance it out more and the website helps a ton. Good luck
