In The end of overeating David A. Kessler writes about the concept of opioid. David A. Kessler defines the word opioid as "The opioid circuitry, which is the body's primary pleasure system. The "opioids", also known as endorphins, are chemicals produced in the brain that have rewarding effects similar to drugs such as morphine and heroin. Stimulating the opioid circuitry with food drives us to eat." Opioid's causes us pleasure, happiness, joy, desire and satisfaction. Opioid's helps us relax and calm us down when we are in pain or stressed out. Opioid's is also used in animals. Opioid's is always caused by the food or drug that you use or eat. When you’re eating something sweet or fattening the brain sends signals to the neurons in the brain that activate the opioids when that happens the opioids releases chemicals into your brain and throughout your body that causes pleasue to you.
