Restrictive eating changes your brain chemistry.
Whenever you restrict your food intake you suffer from a host of mental side effects too. Large scale studies from reputable universities such as Harvard and Oxford have noted that people on diets can significantly deplete their serotonin levels within 3 weeks of dieting. Regardless of your life circumstances or accomplishments, when your serotonin levels drop, so do your feelings of self esteem. As the brain continues to be starved it deteriorates further and becomes even more self critical. This leads to outbreaks of unpleasant psychological problems such as obsessive and compulsive behaviors, depression, anxiety, cravings, general moodiness and poor motivation. Restrictive eating (i.e. bingeing and purging on food) has created:
*Your brain chemistry to change.
*The way you think to change.
*Your personality to become altered.
Simply put....food restriction makes you miserable. (From the book Bulimia Help Method)
