It's not easy, that mind over matter stuff. The eating part is probably more key to the exercize part, at least in the beginning. I used to eat whatever i wanted and ride a lot, thinking i would without a doubt burn more calories than i took in. Well, all that riding made me hungrier, amd my plan didnt work! This December, try writing down everything you eat. Or enter it on one of the workout websites out there. It will make you ponder every cookie and piece of fudge. Workout at the fat burning pace (slow) and try to drink a lot of water and just eat less. Hungry? Try a coffee and a ride and wait til dinner for that food! Wth all that writing you can record your progress on your riding goals. Or, no dinner til you have met your daily goal, on the trainer or the road/trail. Good luck!
