Episode notes
INSIGHT

Models Guide Obesity Science

  • Models integrate data, explain observations, and generate testable hypotheses in obesity research.
  • Kevin Hall says everyone has implicit models and explicit ones guide experiments and interpretation.
INSIGHT

CIM Reverses Causality

  • The carbohydrate–insulin model (CIM) centers insulin as the primary node driving fat storage and downstream overeating.
  • Stephan Guyenet notes CIM reverses causality: fattening processes drive increased intake rather than vice versa.
INSIGHT

  • The energy balance model emphasizes brain circuits integrating genetics and the food environment to regulate body weight.
  • Kevin Hall argues brain regulation and gene–environment interactions explain obesity prevalence and individual susceptibility.
