Toward a definition of a successful dieter.

The purpose of the research was to examine the characteristics of successful weight losers and to compare the findings with a control group of unsuccessful weight losers. The project was designed around a definition of successful dieters, based on the Metropolitan Life Insurance weight tables. The definition, in fact, was not particularly useful. This article describes the difficulties associated with using the original definition as the inclusion criteria for sample selection, the reanalysis of data using the Body Mass Index (BMI), and finally, the creation of a new definition developed from the construction of weight history based on changes in the BMI as an adult. This article presents the final outcome of what a definition of a successful dieter should consist in future research.
