Excessive hunger is the downfall of virtually every weight-loss program. The reason is that hunger was meant to be uncomfortable, even painful so that you would avoid it. Any diet plan that limits the size of your meal and asks you to go hungry is asking you to defeat mother nature. In the long run it can't be done. Hunger triggers the intense desire to gorge on high-fat and calorie rich foods. And like 95% of portion controlled dieters that hate the many discomforts of hunger, you will soon become frustrated and quit.
