Introduction to NIMBioS (Lou Gross)
Introduction of participants
Mathematical body weight regulation models from bench to bedside: Navigating translational research (Diana M. Thomas)
Modeling Human Weight Change
History of Human Weight Change Models (Steven B. Heymsfield)
Setpoint, body composition, metabolic adaptation, and weight loss dynamics (Frank Kozusko)
Open problems in obesity modelling (Carson Chow)

Discussion groups
Breakout Session 1: Parameter Estimation (Chair: Dale Schoeller)
Description: In this breakout session, discussion will focus on how different parameters are
measured and how experiments may be designed to improve their estimation. Some of the
parameters of focus are, baseline total energy expenditures, energy density of fat free mass,
baseline body composition, baseline resting metabolic rate, percent metabolic adaptation, cost of
energy deposition, and the parameter relating the change in spontaneous physical activity to total
energy expenditures during weight change.
Breakout Session 2: Variance and modelling (Chair: Kevin Hall)
Description: Variance in day to day measured weight, total energy expenditures, body
composition, resting metabolic rates can affect modelling and predictions. In this breakout
session, variance in weight over long periods of time will be shown and how this variance
impacts modelling and clinical application of model predictions will be discussed.
Breakout Session 3: Objective Measures of Physical Activity (Chair: Nancy Butte)
Description: There has been an explosion of portable devices to monitor free-living day to day
physical activity. Data collected from the devices are applied to objectively determine physical
activity. In this breakout session, examples of the devices and the resulting data will be shown
and discussion of how to mine and apply the data for use within models will follow.
