Write a weight loss journal while accomplishing your weight loss goals. The journal can contain a list of foods and calories you eat or it can be a journal about your feelings towards weight loss. You can even list pros and cons before considering purchasing a fatty dessert or eating a calorie-laden meal.
One easy way to consume less calories and lose more weight, is to make it a point to leave a portion of your food, uneaten, at each meal. It doesn't matter what it is or how much you leave there. The point is, to allow you to realize that you still feel full, even with a little less to eat.
