Brain chemistry changes with chronic overeating from "summary" of The End of Overeating by David A. Kessler
Chronic overeating doesn't just affect our waistlines; it also alters the very chemistry of our brains. When we consistently consume foods high in sugar, fat, and salt, our brains start to change in response. These highly palatable foods stimulate the release of dopamine, a neurotransmitter associated with pleasure and reward. As we continue to overeat these foods, our brains become desensitized to dopamine, leading us to seek out even more of these foods to experience the same level of pleasure. Additionally, chronic overeating can lead to changes in other neurotransmitters, such as opioids and serotonin, further reinforcing our desire for these highly rewarding foods. The more we overeat, the stronger these neural pathways become, making it increasingly difficult to resist the urge to indulge in unhealthy foods. This creates a vicious cycle where overeating becomes a habitual behavior that is difficult to break. Moreover, research has shown that chronic overeating can lead to structural changes in the brain, particularly in areas responsible for decision-making and impulse control. These changes can make it even harder for individuals to resist the temptation of unhealthy foods and make healthier choices. As a result, overeating becomes not just a behavior, but a deeply ingrained habit that is difficult to overcome.- Chronic overeating doesn't just affect our bodies; it fundamentally alters the way our brains function. By understanding the changes that occur in our brain chemistry as a result of overeating, we can begin to take steps to break free from the cycle of overindulgence and make healthier choices for our overall well-being.
