Diets
Intuitive eating is the opposite of dieting, the latter of which is externally driven. It is a key component of the Health at Every Size movement. Supporters argue that eating in response to internal cues of hunger and fullness, while allowing all foods to be part of the diet, weight will be maintained to one's "natural" weight. Natural weight is the weight range predetermined by genetics.
When someone is disconnected from his or her internal cues of satiety, it is easier to be trigged by external triggers to eat (which can be emotions, "because it's time", opportunity, and/or perceived rules of eating.)
If someone has rigid rules for so-called healthy eating, he or she is more likely to succumb to overeating, as a consequence of breaking their well-meaning rules. Scientifically, this all-or-none type of eating, built around eating rules rather than internal hunger/satiety cues, is referred to as restraint eating or Restraint Theory.
