Oyyyyy! Chewing and spitting is eating disordered behavior. It is extremely unhealthy and can have medical repercussions.For example, people with this disorder can experience physical problems, such as swollen glands, mouth sores, cavities, cracked teeth, sore throats, and irritated or ulcerated stomachs. When a person begins to eat the salivary glands cause stomach acids to flow. Because the person has spit out their food, these acids instead work on the mouth and stomach, resulting in the problems described above. It is also addictive and can lead to other eating disordered behavior. It is NOT a good idea, or reasonable way to manage carbs. I strongly suggest that anyone engaging in this behavior seek help from a therapist experienced with eating disorders. I respect Richard and don't want to make this personal, but I also don't want people to see this as a "useful technique" when it is unhealthy both physically and psychologically. There are many healthy ways to find a reasonable level of carb intake for the individual and cover it with insulin. For those who need to control weight, it's not easy but it can be done without engaging in unhealthy practices. Chewing and spitting might not be as dangerous as diabulimia but it does have consequences and can lead to more severe restricting.
I'm sorry if I've offended anyone but I'm very opposed to presenting eating disordered behavior as healthy or "a useful technique" to manage D.
