If your diet is not working, it could be that you aren't really serious about losing weight. Both cheating on your love and cheating on your diet can lead to disappointment. Consistent weight loss is possible only if you are consistent. We are so focused on our diets during the week that we allow ourselves to indulge on weekends. Or, we believe that dessert is possible if we skip breakfast. Both of these are bad choices. It's easy for you to believe that a small snack will not hurt or that you'll get over it later. It doesn't, and it will never work.
