When planning an operation on a fat individual, the most important issue we pay attention to is how much the person wants to be thin and to stay thin. The main rule of staying thin is that the calories you take and the calories you spend should be in balance. Healthy-unhealthy nutrition is a different situation. You can eat healthy but you can gain more calories than you burn which you causes you to get fat. The golden rule of staying thin is to count calories. If we assume that carbohydrates and fats have high calorie values, we can not stay thin by taking them into our body. At this point, while we decide the best type of surgery for the patient, we determine the patient’s physical need for these foods with tests and we determine his emotional need during the interview. Thus, we decide a method whether in which she /he will only use her/his will such as a tube stomach or a method that will affect him hormonally and detracted her/him from these foods.
