I have to just tell myself I'm going to do this and then not let the spoiled brat inside of me have a temper tantrum over it! Kinda like "time to put on my big girl panties" and be an adult. But that's just me. I find when I change my thought processes about eating healthy its much easier. I have to focus on the fact that eating good results in feeling good. But when I start to feel like I'm being deprived I easily fall back into poor habits. So - staying positive really helps me stay the course.
