I lost about 60 pounds in the space of a year and a half, from 230-240ish to 170. The most important aspect for me at least was to stop drinking anything besides water and beer/liquor. All drinks are unnecessary calories that don't go anywhere. Gradually start to shrink the size of the portions you're eating and after a while it'll fill you up just as much as it did before. Eat red meat as an treat and eat tons of chicken and turkey, if it gets boring after a while, find new ways to prepare it, as long as you give it some flavor, you'll learn to like it. Get on the treadmill at least three times a week, and walk at a brisk pace, staggering the speed in between running, jogging, fast walk, and medium speed walk (i like to run/jog every 2 out of 20 minutes.) If you follow these general rules you'll start to see significant weight loss pretty fast (within two weeks i'd say.) It's ok to cheat but make sure you feel bad enough about it so you won't cheat for a while.
