It is important to remember that being overweight or obese didn't happen over night and it takes building new habits, one at a time to over come. Fast break goals are those "baby steps" that we need. Pick something that you know will help make a difference and whittle at it--after a couple of weeks, add on a new goal to the first one. (If you try to change everything at once, it will probably burn you out and you will "give up.")
I started out with 10 minutes of activity (walking) a day, eating 3 servings of produce, and tracking at least one meal daily. That turned into 5-6 servings of produce which took over for servings of junk food, at least a 2 hour workout in the pool each day, and tracking all my food and activity.
