On the eating spectrum, there seems to be two opposite extremes, obesity and eating disorders. Most people would categorize their eating behavior as normal or between these two extremes. However, these two conditions are still prevalent in society today. Although rare, eating disorders and obesity have a long history of origin. These conditions, while requiring attention and response, created other concepts and theories. Restraint theory is one that stemmed from curious minds of different eating behavior. Through the progression of the theory, many dependent variables have been tested to see the effects on restraint eating. However, the connection of soda or sugary drink consumption has not been investigated yet. There may be a connection between obesity, eating disorders, restraint eating, and soda or sugary drinks consumption.
Obesity is now a medical condition in which one’s excess body fat causes adverse medical, physical, and emotional issues. People are considered obese when their body mass index (BMI) is over 30kg/m2. Body mass index is calculated by dividing a person's weight in kilograms by the square of the person's height in meters. Obesity originally was viewed as the body‘s natural response to store fat for survival through harsh times of famine. “This ability to store surplus fat from the least possible amount of food intake may have made the difference between life and death, not only for the individual but also—more importantly—for the species. Those who could store fat easily had an evolutionary advantage in the harsh environment of early hunters and gatherers” (Eknoyan. G, A History of Obesity…). Those who were obese were seen as superior, even so that statues were modeled after them. The best known of these early representations of the human form is the Venus of Willendorf, found in Australia of 1908. It displays a squat body, bulbous contours, pendulous breasts, and prominent belly are as esthetically a factual rendering of gross obesity as can be. In the long term, chronic food shortage has been more deadly to humankind. Only after the technological advances of the eighteenth century, did a gradual increase in food supply become available. Although the body was well maintained, it was deprived of nutrients. This is one of the major effects of fast, processed, and cheap food.
However, obesity is not alone. On the other end of the spectrum are eating disorders. Anorexia nervosa and Bulimia are two of the most common eating disorders. Anorexia is a complicated condition of wanting to be thin (less than ideal weight) at extreme measures while Bulimia is the condition of a repeated cycle of binge eating and then purging by vomiting, laxatives, and extreme exercise. All in all, these eating disorders paved a pathway for the development of restrained eating. With a history of itself, restraint eating has its own story to tell.
The term restrained eating was adopted because of the pioneering research conducted by...
