All solid things are blown to vapor in me refers to a work that had the objective of investigating morbid obesity beyond mere accumulation of fat. The hypothesis is that obesity is paradigmatic of a hedonistic society that valorize the body and its autonomy, because it is the sickening par excellence of this society in a way that it relates directly to these characteristics. Taking as a reference the psychoanalytic theory, this work was also an attempt to understand the deadly connection between obesity and food, hypothesizing that the obese is an individual who is not able to cope with the radical lack that constitute his/her being. Thus, the methodology should cover the complexity of the object as well as the wealth of the subjectivity involved, approaching deeply the meanings of human actions and relationships, which are not easily perceived in equations and statistics. Statements from patients of a public hospital were used as a guide and also as a clinical vignette, which brought consistency to the theory. It is necessary to analyze accurately the way morbid obesity has been dealt; otherwise, society will have a means of controlling man and his body, and if this obese subjectivity is silenced, it will become more obscure and harder to handle.
