Highly processed foods override body's natural signals from "summary" of The End of Overeating by David A. Kessler
Highly processed foods have the power to hijack our brain's natural signals, leading us down a path of overeating and weight gain. These foods are carefully engineered by food scientists to have the perfect combination of fat, sugar, and salt that make them incredibly rewarding to our brains. When we consume these foods, our brain releases dopamine, a neurotransmitter that is associated with pleasure and reward. This dopamine response reinforces the behavior of eating these foods, creating a cycle of cravings and overeating. Additionally, the highly processed nature of these foods means they are often stripped of their natural nutrients and fiber, which help our bodies regulate hunger and fullness. Without these essential components, our body's natural signals become overridden, and we are left feeling unsatisfied and constantly craving more food. This can lead to a pattern of overeating and weight gain as we continue to seek out these highly rewarding foods to satisfy our cravings. Furthermore, the hyperpalatability of highly processed foods can lead to a phenomenon known as sensory-specific satiety, where our brain becomes desensitized to the flavors and textures of a particular food. This desensitization makes us more likely to seek out new and different flavors, leading us to consume a wider variety of foods and ultimately consume more calories than we need.- Highly processed foods have the ability to override our body's natural signals of hunger and fullness, leading us to overeat and gain weight. By understanding the powerful impact of these foods on our brains and bodies, we can begin to make healthier choices and break free from the cycle of overeating and weight gain.
