In the 80/10/10 diet 80% of food consumed should consist of good carbohydrates 10% should be protein and 10% should be healthy fat. The best way to succeed with this kind of diet is to keep a diet journal. The reality is that most people eat because of emotions not hunger. This explains the overeating phenomenon. A journal helps keep track of food consumed but should also be used to record the emotions associated with a dieter's cravings.
