It is easier to squeeze excess eating out by wanting to do something else than by sheer will power.This is such an important aspect of successful diet and lifestyle. To understand it, just think of those days when you are very busy with work (or play) and "only" manage to squeeze in three meals with no snacking. The time flies and you never even thought about snacking.Another way this could be said: The best way to stop a bad (eating) habit is to replace it with a good habit. Stopping the bad habit with no other changes is doomed to failure. A change can be either direct (e.g., replace soda with water) or indirect (e.g., increase activity level to reduce boredom eating). Indirect change often works because humans don't deal well with dissonance. That is, the new good habit eventually makes the old habit seem silly - poor eating no longer makes sense in your life.For example, it is the wrong mindset to quit smoking so one can start exercising. Instead, one should indirectly REPLACE smoking with exercise. I helped a friend quit smoking (and start exercising) with this mindset. (Granted, he was already willing to stop smoking.) I told him to smoke as much as usual every other day, but to not smoke at all on the days he exercised. If he missed a day of exercise he had to exercise the next day, which resulted in two days of not smoking. After just a few weeks he started smoking less on his smoking days because (he said) it stopped making sense to smoke. He was really enjoying weight lifting and knew smoking (even on his "off days") was hurting the amount he could lift. In other words, smoking no longer made sense within the context of his new lifestyle.
