Endorphins may also have a positive effect on food cravings, especially carbohydrates. According to The Diet Channel, exercise that releases endorphins may satisfy the brain's need to create balance during times of stress. Such stressful times encourage overeating or cravings for unhealthy foods, which also release endorphins. Substituting exercise or other activities that release the same endorphins may help eliminate cravings for sugary or fatty foods.
