The eating binge is something that's well known to most of us ? especially those of us who are struggling to lose weight. In extreme cases, binge eating is even a disorder ? people seem to lose control of their eating, concentrating on a single food group and consuming literally thousands of calories in a very short period of time. Afterward, the result is a feeling of guilt, or that you have ?blown it? ? and, of course, the intake of that many calories at a time is disastrous to weight loss.

However, many experts have commented that dieting or restricting food intake can actually trigger binging for those who have that tendency already. It's almost as though the restriction of food makes us feel so deprived that we respond by binging, and the guild that follows a binge can derail the diet for an even longer time that necessary. Many of us would give anything to be able to control the impulse to binge ? eliminating it altogether would be ideal, in fact. In this way, we would really be able to control food intake and lose weight.

Most people look upon binging as a ?problem? behavior ? an expression of some sort of distress, or even a type of neurotic behavior to be cured. After all, this type of eating is extreme ? during a binge, people consume many times their ideal calorie intake for the day, and there seems no way to avoid weight gain if this becomes a habit. However, there is also evidence that indicates binging may just be a fact of life for all humans, a leftover from the way in which we obtained our food early on in human development. Think about it. Before agriculture came on the scene and regulated the food supply throughout the year, humans spent many millennia as hunters and gatherers. In fact, we should all remember that this pre-civilized, hunting and gathering existence went on for much longer than civilization had. Humans have practiced agriculture for little more than six thousand years, but humans (or advanced pre-humans) have been around for about 35 thousand years. So for the vast majority of human history, we were hunters and gatherers, and in that state, believe it or not, binging was a really good idea.

Think about it. This was before refrigeration or any other organized means of food preservation. People moved around constantly, and sometimes food was plentiful, while other times it was scarce. When food was scarce, there was no way to get more. Humans just had to do without, or survive on very little. That meant that when a hunt was successful, or when the early humans stumbled upon a grove or fruit trees, binging was the most reasonable, well-adapted response. The food was there at that moment, and who knew when it would be there again? So the early humans would have eaten as much of it as was humanly possible ? in short, they binged. They had to. It had to keep them going until the next lucky find.

Our bodily drives are stronger and more primitive than what our minds tell us. So, while we might know, intellectually, that binging is not a good idea and that we should eat a pre-approved number of calories per day, the urge to binge is still as strong in us as it was in early humans. The difference, of course, is that our food environment is not self-limiting ? there are no natural restrictions. We have access to almost all types of food at all times, unlike early humans. So, though our environment doesn't necessitate binging, the behavioral drive is still strong.

That also explains why dieting can bring on a binge. A diet is like a period of scarcity or famine ? biologically, this makes us want to binge, to make up for it, as soon as food becomes available. And the more you restrict your eating, the stronger your impulse to binge will be, because for early humans (physiologically identical to us) that was good survival behavior. That's why the behavior is so hard to overcome ? at one point, it was not just acceptable ? it was necessary to human survival.
