I found the motivation to exercise two summers ago, when I was 205 pounds. Within two and a half months, I was down to 165 and feeling all foxy.
I used Wii Fit mostly, but also, I exercised while doing things I enjoyed. Also, I would squeeze in small things everywhere. Running to my car, laying down and down 10-20 pushups, curls, or lunges between rounds on Halo or any multiplayer game or on loading screens. I found the times when I was sitting there waiting, and filled them with things that took more energy, but were during times I wasn't doing anything anyways.
In addition to that, I didn't necessarily change what I was eating, but how much I was eating. For example, getting a smaller portion at Moe's (or Chipotle, depending on where you live) or just not finishing off the last of something I had put on my plate. Leftovers are your friend. I still got to enjoy eating what I wanted, but just ate less! Also...drink a TON of water! Like, buy a water bottle and keep filling it up! That will help you more than you know. These are habits that will change your life forever if you keep it up. It also doesn't require cutting out nomming those tasty things.
Pretty soon, you'll start losing pounds doing things that take -no extra time.- Then, you can move on to doing things that will REALLY start toning you up.
Hope this helps! You can ask me anything if you want.
