What I ask people to do is to get on the scale every day. Yes, every day. Write down your weight each day and average it out over the course of a week. This keeps you awake and aware to what is going on.
Mindful eating is important because it is a long-term approach to eating (versus dieting which is short term). Mindful eating is realistic. It doesn't cut out any foods from your diet. When you slow down, you think more clearly.
