This can also lead to binge eating disorder and cycling through various diet programs. Definition Article Talk. In these experiments, restoration of MC4R expression in glutamatergic neurons was sufficient to rescue normal body weight in these otherwise obese knockout mice, while restoration of MC4R expression in GABAergic neurons produced minimal effects on body weight changes, suggesting that, in mouse at least, MC4Rs on GABAergic neurons are not key in regulating body weight.

  • While we cannot rule out that DIO-D animals reduced their energy expenditure to help defend the higher body weight, it is evident that they consumed the same number of calories on chow as they did earlier on HED.

In humans, when calories are restricted because of war, famine, or diet, lost weight is typically regained quickly, including for obese patients. Proponents of the set point theory cite the following supporting facts as evidence of the theory:.
