Abstract
Recent research findings reveal that human bioenergetics belongs to the class of multi-loop nonlinear feedback systems - the same class of systems that system dynamics aims to study. In this paper the author aims to
demonstrate the utility of utilizing simple - bathtub like - system dynamics models to gain insight into human
weight and energy regulation and (in the process) help debunk widespread misconceptions that are hindering
prevention and treatment efforts. Specifically, the author presents a series of models, starting with one that
captures conventional wisdom about human energy regulation. This baseline model is critiqued and its limitations - and pitfalls - exposed through model experimentation. The model is then incrementally refined in a
spiral of modeling-experimentation-learning steps, to arrive at a structure that integrates emerging (advanced)
conceptualization(s) of human weight/energy regulation. In the concluding section, the author builds upon the
insights gained from this modeling exercise to propose recommendations for obesity treatment and prevention.
