Set realistic goals:

Successful weight loss doesn't happen overnight, it takes months and years, not days and weeks. Concentrate more on changing your habits than you do on what your bathroom scales say and with time what they tell you will start to reflect the changes you've made in your life.

Eat more than 3 meals a day. If you've ever dieted before you'll know that 3 meals a day just doesn't cut it; particularly when the new diet severely restricts calories.
When we restrict calories, our body senses it and slows down our metabolism (the rate at which it burns energy) to compensate. One way of overcoming this is to eat smaller meals more frequently, say every two or three hours or five to six times per day.



Keeping a log of what you eat, when and why you eat it allows you to look at the big picture and learn more about your eating habits.
Be sure to write down as much information as possible and use the knowledge you gain to plan ahead and change your daily eating habits for good.

Don't get too caught up on what you weigh. Scales don't differentiate between body fat and muscle and body weight is only one of the measures that can provide us with feedback about our progress.
So what if you've only dropped a kilo or two, or even weigh the same as you did when you started! The important thing is, do you look and feel better?
