There is a need for researches to understand multiple approaches to defining obesity and how and why the standard definition was developed. The review will help to grasp the complexity of the problem and can lead to novel hypotheses in obesity research. Objective. This paper focuses on the objective to understand historical background on the development of "reference and standard tables" of weight as a platform for normal versus abnormal body weight definition. Methods. A systematic literature review was performed to chronologically summarize the definition of body weight from time of Hippocrates till the year of 2010. Conclusion. This paper presents the historical background on the development of "reference and standard tables" of weight as a platform for normal versus abnormal body weight definition. Knowledge of historical approaches to the concept of obesity can motivate researchers to find new hypotheses and utilize the appropriate obesity assessments to address their objectives.
