FOOD ADDICTION: REASONS WHY IT OCCURS

                  FOOD ADDICTION: REASONS WHY IT OCCURS 

     Research shows that up to fifty percent of those who are obese may be addicted 
to food. Thirty percent of overweight and twenty percent of normal weight 
Americans may be addicted to specific foods or food quantity in general. 
Food addiction is recognized today as a chronic disease that changes both brain 
structure and function. The first time a person enjoys an addictive experience, 
the brain’s pleasure or reward center “ lights up” when it secretes dopamine 
that binds with its receptor called the D2 receptor. When this occurs, the brain 
experiences a “hit”” of pleasure and reward. When the neurotransmitters 
Glutamate and Dopamine combine, they create the memory of the “high”.  
The next time a person eats their Crispy Creamy Donut, the brain’s reward center 
is activated. Repeated over stimulation of this reward center leads to receptor 
resistance and decreasing sense of pleasure or reward. A person doesn’t feel 
anywhere near the pleasure and reward once enjoyed.  This creates a new 
tolerance which means a person wants more and more of the fix but never achieves 
the same “high”  again. The addictive cravings grow stronger. 
     Repetition causes our brain function to change from” liking” to” wanting” and  a 
person’s reasoning and emotions begin a “tug of war” to control the addictive 
behavior. Compulsion takes over and intense cravings follow based on the brain’s 
memories of the highs and lows. The positive effects of a master hormone called 
Leptin are interrupted and the body no longer “hears” the messages telling it to 
stop eating and to burn fat.
