A November 2022 study by DZD, Tübingen University Hospital and Helmholtz Munich said, 

  • "The exercise intervention increased the insulin-stimulated activity in brain regions that are responsible, among other things, for the perception of hunger and satiety and for the interaction of motivation, reward, emotion and exercise behavior," 

  • "The study suggests that insulin resistance in the brain may be reversible and could be a viable therapeutic target to restore central nervous system regulation of metabolism and body weight and counteract adverse effects of obesity,"
