Title: The dynamics of obesity
The past two decades have seen a surge in the incidence of obesity in
the developed world. Changes in body weight that can lead to obesity
are known to result from imbalances between the energy derived from
food and the energy expended to maintain life and perform physical
work. However, quantifying this relationship has proved difficult.
Here, I will show how simple concepts from dynamical systems can be
used to provide a general quantitative description of how body weight
will change over time. The model can then be used to answer open
questions (and dispel some myths) regarding weight loss and gain and
provide an explanation for the American obesity epidemic.
