Obesity researchers in the 1960s focused on energy balance imbalance and ignored fat metabolism science.

“obesity research in the 1960s is dominated by psychiatrists and psychologists trying to get fat people to eat less people like mickey stunkert who was a wonderful man but his expertise was psychology and this idea that obesity is a hormonal dysregulation of fat storage fatty acid oxidation and storage a fuel partitioning disorder gets left out of the field”

“by the mid 1960s you have very well established science of what we could call intermediary metabolism which is what the researchers what your body does with the foods the proteins fats and carbohydrates after you eat them and then what your body continues to do to make fuel available as necessary to your body and all of this is left out of the science of obesity”
