I've found the best method (at least for me) to lose weight (and hopefully start a eating lifestyle change) is to log EVERYTHING I eat into a calorie counting program. I'm using an excellent (and free) program called Loseit! on my iPhone. Always with me. Allows you to set goals for losing weight and track all food intake and excersize. I'm staying on a 1500 cal, net intake for a weight loss of 2 lbs/week. (Lost around 12 lbs since early Jan....about 8-10 to go.)
