The great thing about goal setting for weight loss is that you have complete control over how aggressively you want to get to your results. If you have difficulty with compliance, and keeping up the behaviors that will help you lose weight, then you should go with a less aggressive goal such as half a pound per week.
Of course, this means that it will take you more time to hit your long term goal, but the good news is that the journey might not be quite as difficult. If you want to lose half a pound per week, you will only need to create a daily deficit of 250 calories. Translated into actions, this could mean simply eating one less slice of cheese (about 100 calories) and taking a 20 minute walk (burning an additional 150 calories).
